s2-netbox-mcp

A local MCP server that exposes LenelS2 S2 NetBox NBAPI operations — persons/credentials, access levels, portals/readers/outputs, time specs, holidays, portal/reader groups, threat levels, events/activity, and partitions/UDF lists — as MCP tools usable from any MCP-compatible client (Claude, Gemini/Antigravity, etc.).

Not the open-source netboxlabs.com "NetBox" DCIM/IPAM tool. This targets LenelS2's S2 NetBox physical access-control appliance and its NBAPI (Web-Based API for S2 NetBox and S2 Global, LenelS2 doc #API-UG-14). Newer NBAPI v1 (doc #API-UG-22, April 2024) and v2 (doc #API2-UG-8, April 2025) guides also exist — see docs/reference/ for reference copies. Both have now been diffed against this server's tool surface command by command and parameter by parameter: docs/reference/nbapi-command-diff.md records the result, including which documented commands are deliberately not implemented and why.

[!WARNING] This connects to a real physical security system. With the wrong configuration, an AI agent using this server could unlock doors or modify access-control data on a live building. It is read-only by default — writes and destructive operations (lock/unlock, add/modify/delete) each require their own explicit opt-in environment variable (see Write access below) — but you are responsible for what you enable and which MCP client/model you point at it. See SECURITY.md before deploying anything beyond read-only against a production controller.

Read-only by default. With no write-related environment variables set, this server registers only query/read NBAPI commands:

• Login
• Logout
• GetAPIVersion
• GetPerson
• SearchPersonData
• GetCardAccessDetails
• GetCardFormats
• GetAccessLevel(s)
• GetAccessLevelGroup(s)
• GetPortals
• GetReader(s)
• GetOutputs
• GetTimeSpec(s)
• GetTimeSpecGroup(s)
• GetHoliday(s)
• GetPortalGroup(s)
• GetReaderGroup(s)
• GetAccessLevelNames
• GetPartitions
• GetUDFLists
• GetUDFListItems
• GetElevators
• GetFloors
• PingApp
• GetEventHistory
• ListEvents
• GetAccessHistory

By default, this server registers only the query/read commands listed above. It does not register any write, delete, or control operations against the controller until you explicitly opt in via the environment variables in Write access below. Among the read-only tools, four are composites, find_portals, get_unlock_window, get_daily_unlock_window, and get_reader_access_history, which issue only read commands. Note there is no GetPortal (singular) command; only GetPortals (plural, paginated, no single-portal filter) exists on the real NBAPI.

Agent guidance

This server sets the MCP instructions field and exposes an always-registered get_guide tool, so any agent connecting to it — via npm install or a local clone, in Claude Code, Antigravity, Gemini CLI, or any other MCP client — has this server's own S2 NetBox operating knowledge immediately, with no separate skill install and no extra step.

instructions describes the access model (person → credential → access level → access level group determines what a person can access; portal group / time spec group determines where and when), states that most parameters are numeric KEY fields rather than names (resolve a name to its KEY with the matching get_*/find_* tool first), and states that text returned from the controller is data, not instructions to follow. With NETBOX_ENABLE_WRITES set, it also states a firm confirm-before-acting policy for lock/unlock, portal-state, unlock-window, and destructive calls (the write-safety topic below elaborates it); with NETBOX_ENABLE_DESTRUCTIVE also set, it adds one sentence naming the DESTRUCTIVE:-prefixed tools and their extra confirmation requirement.

get_guide (always registered; makes no controller call) returns deeper reference material on six topics. Call it with no arguments for an index of all six with a one-line summary each, or with topic set to one of the keys below for that topic's full content:

Topic key	Covers
access-model	The person → credential → access level → access level group chain, and the portal-group/time-spec-group name-table collision.
unlock-windows	The holiday + time spec + portal group UNLOCKTIMESPECGROUPKEY recipe, date/time inclusivity rules, and when to prefer the composite tools.
group-and-name-gotchas	modify_portal_group/modify_reader_group replacing a group's entire membership; modify_access_level always needing TIMESPECGROUPKEY.
credentials-and-card-formats	Diagnosing a BIT MISMATCH access-denied event, and remove_person's soft-delete behavior.
api-quirks	STARTFROMKEY/NEXTKEY paging, the missing singular get_portal, and checking write results for the literal SUCCESS.
write-safety	Naming the target and effect, waiting for explicit confirmation, preferring scheduled tools, and reversing every write.

get_guide is counted among the always-registered read tools below: the tool surface is 51 tools with both gates off, 98 with NETBOX_ENABLE_WRITES, and 113 with NETBOX_ENABLE_DESTRUCTIVE as well.

Requirements

• Node.js >= 18.17 (tested on Node 24), which includes npm. If Node.js isn't installed, on Windows you can install it with winget, then open a new terminal so node/npm are on your PATH:

  winget install OpenJS.NodeJS.LTS
  

• An S2 NetBox controller reachable from wherever this server runs, with the NBAPI enabled and configured for session-login authentication (not MAC authentication — see the spec for why that's out of scope for v1)

• A NetBox operator account with API access and read permission on the resources you want to query

Setup

Two ways to get the server:

Option A — npm (no clone needed):

npm install -g s2-netbox-mcp

This installs the s2-netbox-mcp binary; point your MCP client's command at s2-netbox-mcp directly (no node dist/index.js needed).

Option B — clone and build:

npm install
npm run build

Either way, copy .env.example to .env and fill in real values (or provide the same variables directly in your shell / in the Claude Code MCP server config's env block — see below). Never commit .env — it's already gitignored.

cp .env.example .env
# edit .env

Start the server directly to sanity-check it boots (it just waits on stdio for an MCP client — Ctrl+C to stop; this also sends Logout if a session was opened):

npm start

Environment variables

Variable	Required	Default	Description
NETBOX_BASE_URL	Yes	—	Base URL of the NetBox controller's web interface, e.g. https://netbox.example.internal. No trailing slash or path — the client appends NETBOX_API_PATH itself.
NETBOX_USERNAME	Yes	—	NBAPI session-login username.
NETBOX_PASSWORD	Yes	—	NBAPI session-login password. Never logged, never written to any tracked file.
NETBOX_ALLOW_INSECURE_TLS	No	false	Set to true/1/yes to accept a self-signed/on-prem TLS certificate. Explicit opt-in only — any other value (including unset) keeps normal certificate verification.
NETBOX_API_PATH	No	/nbws/goforms/nbapi	The NBAPI path appended to NETBOX_BASE_URL. The default is the verified path on NetBox 6.x controllers. Only set this to override the default — e.g. to the legacy, pre-6.x path /goforms/nbapi, which returns HTTP 410 Gone on 6.x controllers (see Controller prerequisites below). A value without a leading / has one added automatically.
NETBOX_ENABLE_WRITES	No	false	Set to true/1/yes to register the write tools (see Write access below). Unset (or any other value) leaves the server strictly read-only.
NETBOX_ENABLE_DESTRUCTIVE	No	false	Set to true/1/yes, together with NETBOX_ENABLE_WRITES, to additionally register the 11 destructive tools (see Write access below).
NETBOX_EVENT_API_PATH	No	tracks NETBOX_API_PATH	Request path used only for trigger_event. Unset/empty tracks whatever NETBOX_API_PATH resolves to; a non-empty override is used verbatim (leading / added if missing) — e.g. the doc's pre-6.x Event API path /appd/nbapi, if your controller serves it separately.
NETBOX_UNLOCK_HOLIDAY_GROUPS	No	8,7,6	The holiday groups reserved for the managed unlock window, in first,middle,last segment order — see Scheduled unlock windows below. Must be 1-3 distinct integers in 1..8, comma-separated; reserve groups nothing else on the controller uses.
NETBOX_UNLOCK_NAME_PREFIX	No	MCP Unlock Window	Name prefix of every object the managed unlock window creates: the portal group (<prefix>), the time spec group (<prefix> time specs), and the per-segment holidays/time specs (<prefix> first/middle/last). 1-40 characters so the longest name (<prefix> time specs) fits the 64-character NAME limit.
NETBOX_DAILY_UNLOCK_HOLIDAY_GROUP	No	5	The single holiday group reserved for the managed daily recurring unlock window — see Scheduled daily unlock windows below. Must be a single integer in 1..8, and must not be a member of NETBOX_UNLOCK_HOLIDAY_GROUPS (the two features' reserved groups can never collide).
NETBOX_DAILY_UNLOCK_NAME_PREFIX	No	MCP Daily Unlock Window	Name prefix of every object the managed daily unlock window creates: the portal group (<prefix>), the time spec group (<prefix> time specs), and the one holiday/time spec (<prefix> schedule). 1-40 characters so the longest name fits the 64-character NAME limit.
NETBOX_LIVE_TEST_PORTALKEY	No	—	The PORTALKEY of the one door you designate safe to physically unlock during npm run test:live:write/npm run test:live:write:daily. Read only by those scripts, never by the server itself.

If any of the three required variables is missing, the server prints a single actionable line to stderr and exits with a non-zero status — it never prints a stack trace on startup misconfiguration.

Write access

Write/control tools exist in this server but are not registered unless you explicitly opt in:

• NETBOX_ENABLE_WRITES=true registers the write tools listed in the "Write tools" table below — the 45 pass-through tools (creating, modifying, locking/unlocking, activating, and triggering) plus the three composite write tools set_portals_state, schedule_unlock_window, and cancel_unlock_window. Left unset (the default), the server's tool surface is exactly the read tools below — byte-for-byte the same read-only posture as before this variable existed.
• The two unlock-window composites delete only the holidays and time specs they themselves own (named <prefix> first|middle|last — see Scheduled unlock windows), and do so without NETBOX_ENABLE_DESTRUCTIVE because those objects are server-owned; they never delete anything else.
• NETBOX_ENABLE_DESTRUCTIVE=true, set in addition to NETBOX_ENABLE_WRITES, registers the 11 destructive tools (each description is DESTRUCTIVE:-prefixed): delete_access_level, delete_access_level_group, delete_holiday, delete_portal_group, delete_reader_group, delete_time_spec, delete_time_spec_group, remove_credential, remove_person, remove_threat_level, remove_threat_level_group. Two ordinarily non-destructive write tools also independently refuse one specific destructive-shaped call when this flag is off, regardless of whether the tool itself is registered: modify_person refuses a call with DELETED="TRUE" or PERSONPURGE="TRUE", and modify_udf_list_items refuses a call where any list item has DELETE="1" — both name NETBOX_ENABLE_DESTRUCTIVE in the error and send nothing to the controller.
• Every write tool's description starts with WRITE: (or DESTRUCTIVE: for the 11 above), and every successful write's result text contains the literal SUCCESS followed by the controller's response data as pretty JSON (which may be {} when the command returns no data), so you can always tell a write actually happened.
• Client-side guards (e.g. "give either READERKEY or READERGROUPKEY, not both") reject malformed calls with a tool error before any NBAPI command is issued — no partial or guessed request ever reaches the controller.

Set these the same way as the other variables — in .env (see .env.example) or your MCP server config's env block.

Controller prerequisites

Before this server can talk to your controller, on the NetBox web UI go to Configuration → Site Settings → Network Controller → Data Integration and confirm all three of these are checked:

• Enable V2
• Use Authentication
• Use login username/password for authentication (requires setup privilege)

The NBAPI user account also needs a role with NBAPI read access (see the NBAPI doc's "Setting Up User Roles for the API" section) — a login that succeeds but can't read the resources this server queries will surface as FAIL or APIERROR responses per tool call. If you set NETBOX_ENABLE_WRITES, that role needs Read-Write API privilege instead (Configuration → Site Settings → User Roles → API Privilege) — Read-Only suffices only for the read tools.

Troubleshooting

• "Login succeeds but every other command returns APIERROR 5." This is the live-observed symptom of the Use login username/password for authentication (requires setup privilege) checkbox being unticked, which puts the controller in MAC-authentication mode instead of session-login mode (MAC auth is out of scope for this server — see the spec). Login still returns SUCCESS with a session ID, but every subsequent command — including Logout — fails with APIERROR 5. Fix: tick that checkbox on the Data Integration tab. This server's client detects this exact pattern (a successful re-login followed by another APIERROR 5) and surfaces a tool error naming the checkbox directly.
• "HTTP 410 Gone." The configured NETBOX_API_PATH is not served by this controller. NetBox 6.x serves the NBAPI at /nbws/goforms/nbapi (the default this server uses); the 2020 doc's /goforms/nbapi path is deregistered on 6.x and returns 410 for every request. If you're on a pre-6.x controller, set NETBOX_API_PATH=/goforms/nbapi explicitly; if you're on 6.x and still see this, double-check NETBOX_API_PATH isn't set to something else by mistake.

Registering with an MCP client

This server works with any MCP client that speaks the standard mcpServers stdio config shape — Claude Code, Antigravity, and Gemini CLI have all been verified against it directly. Which JSON to use depends on which Setup option you picked above:

If you installed via npm (Setup Option A):

{
  "mcpServers": {
    "s2-netbox-mcp": {
      "command": "s2-netbox-mcp",
      "env": {
        "NETBOX_BASE_URL": "https://netbox.example.internal",
        "NETBOX_USERNAME": "svc-account",
        "NETBOX_PASSWORD": "REPLACE_ME",
        "NETBOX_ALLOW_INSECURE_TLS": "false"
      }
    }
  }
}

If you cloned and built locally (Setup Option B):

{
  "mcpServers": {
    "s2-netbox-mcp": {
      "command": "node",
      "args": ["/absolute/path/to/s2-netbox-mcp/dist/index.js"],
      "env": {
        "NETBOX_BASE_URL": "https://netbox.example.internal",
        "NETBOX_USERNAME": "svc-account",
        "NETBOX_PASSWORD": "REPLACE_ME",
        "NETBOX_ALLOW_INSECURE_TLS": "false"
      }
    }
  }
}

Replace the args path with the actual absolute path to dist/index.js on your machine, and replace the env values with your real controller details (or omit env entirely and rely on a .env file next to the project if you prefer — either works, since src/index.ts loads .env via dotenv before reading process.env). Run npm run build first so dist/index.js exists.

Where to put that JSON depends on the client:

Client	Config file	Notes
Claude Code	.mcp.json in your project, or claude_desktop_config.json	Or add non-interactively via claude mcp add-json s2-netbox-mcp '<json>'
Antigravity	~/.gemini/config/mcp_config.json (Windows: %USERPROFILE%\.gemini\config\mcp_config.json)	Global — applies to every Antigravity session
Gemini CLI	~/.gemini/settings.json, under its own mcpServers key	Or add non-interactively via gemini mcp add s2-netbox-mcp <command> [args] -e KEY=value

All three use the identical mcpServers object shape shown above — only the surrounding file and location differ.

There is deliberately no get_portal (singular) tool — no such NBAPI command exists; only GetPortals (plural) does. get_card_access_details and get_access_history identify a card by ENCODEDNUM/CARDFORMAT (and get_access_history optionally by HOTSTAMP), not by PERSONID — neither command has a PERSONID parameter.

Every read tool except find_portals returns a thin JSON pass-through of that NBAPI command's response fields — no reshaping. Each tool's input schema declares exactly the documented PARAMS fields for its command — no invented, renamed, or passthrough fields. All NBAPI parameter names above are copied verbatim from the NBAPI Command Reference (see specs/archive/s2-netbox-mcp-write.md and the archived specs/archive/s2-netbox-mcp.md) — none are invented or guessed.

Nine tools are composites — they combine several NBAPI commands and reshape the result instead of passing one command through: find_portals, get_unlock_window, get_daily_unlock_window, and get_reader_access_history (read-only, always registered), and set_portals_state, schedule_unlock_window, cancel_unlock_window, schedule_daily_unlock_window, and cancel_daily_unlock_window (write, registered only with NETBOX_ENABLE_WRITES). Every composite reads list commands fully paginated (following NEXTKEY until -1, or AFTERLOGID/NEXTLOGID over a bounded SCANWINDOW for get_reader_access_history) and issues only commands from the closed allowlist. set_portals_state locks, unlocks (Extended Unlock until locked again), or momentarily unlocks many portals in one call — the given portalKeys or every portal — issuing one command per portal sequentially and never stopping on a single failure; its result partitions the portals into succeeded, alreadyInState (the controller's "Portal state not changed"), and failed, and is an error only when failed is non-empty. The five unlock-window tools are described under Scheduled unlock windows and Scheduled daily unlock windows below.

find_portals is for finding a door when you only know where it is. Portal names are site codes (01OF05A), and the only human-readable location text on the controller is each reader's DESCRIPTION. GetPortals doesn't return it, and neither command takes a filter. So find_portals reads every page of GetPortals and GetReaders, joins them by READERKEY, and returns the portals where every term of query appears (case-insensitive) in the portal name, a reader name, or a reader description. For example, "maintenance office" matches a reader described as BREAKROOM TO MAINTENANCE OFFICE. Each match includes its readers' names and descriptions. The result also lists portalsWithoutDescriptions: portals none of whose readers has a description, which can only be found by name. It issues no commands beyond those two.

get_portals itself also accepts RESOLVEDESCRIPTIONS (default true — on by default, the same opt-out default as every other RESOLVEDESCRIPTIONS flag in this codebase): unless explicitly set to false, it fills in each nested reader's own DESCRIPTION field — GetPortals never populates it, only READERKEY/NAME/PORTALORDER — via one GetReaders full-table fetch per call (not per portal/reader), using the same src/readerDescriptions.ts helper as the other RESOLVEDESCRIPTIONS tools. Unlike those tools, which add a new sibling field (READERDESCRIPTION) to flat records, this fills DESCRIPTION in directly on each nested reader object, since that's that reader's own native GetReaders field name. Set RESOLVEDESCRIPTIONS: false to get readers back exactly as GetPortals returns them, with no GetReaders call. This makes plain get_portals listings self-describing; it doesn't replace find_portals, which remains the tool for searching by name or description rather than just listing.

get_reader_access_history is for finding out who actually badges through a given reader — useful, for example, when a reader has no DESCRIPTION and find_portals can't locate it by name. GetAccessHistory has no READERKEY/PORTALKEY filter, so this tool reads and filters client-side. Rather than a date range (a real one proved unworkable live — see specs/archive/get-reader-access-history.md's Goal section), it scans a fixed-size window of the most recent SCANWINDOW system-wide records (default 2000): one cheap MAXRECORDS: '1' call discovers the current maximum LOGID, then the tool walks forward from maxLogid - SCANWINDOW via its own AFTERLOGID/NEXTLOGID pagination loop (a separate shape from NEXTKEY), keeping only the records whose READERKEY matches. Each matching record's PERSONID is enriched with FIRSTNAME/LASTNAME via one GetPerson call per distinct person (a lookup failure — e.g. for an operator-style PERSONID — leaves those two fields blank rather than failing the call). The result is capped at MAXMATCHES (default 100, earliest matches first) with a truncated flag. get_reader_access_history also accepts RESOLVEDESCRIPTIONS (default true — on by default, the one opt-out boolean in this codebase; every other optional boolean flag defaults to off): unless explicitly set to false, it attaches a single top-level READERDESCRIPTION field — the human-readable description of the call's own READERKEY — via one GetReaders full-table fetch. It is deliberately not duplicated onto each matches entry, since every match already shares that identical READERKEY by construction. Set RESOLVEDESCRIPTIONS: false to omit the field entirely (not present at all, distinguishable from an unknown reader's '') and skip the GetReaders call.

get_access_history optionally enriches each returned record with the badge-holder's name via RESOLVENAMES: true (default false): when set, it calls GetPerson once per distinct PERSONID found in the result (the same per-request memoization as get_reader_access_history, via the shared src/personEnrichment.ts helper — no cross-request cache) and adds FIRSTNAME/LASTNAME/FULLNAME/NOTES to each record, preserving every original field. This costs one extra GetPerson call per distinct person in the result, which is why it's opt-in rather than on by default. get_access_history has no date-range filter: its previous date-range parameters were removed entirely, closing #47 — they didn't match GetAccessHistory's real NBAPI field names, and a live controlled A/B test this session found that even the correct field names don't work: the controller silently ignores them and returns the same records regardless of the requested range, no error, just no effect. Renaming would have only traded a loud failure for a silently wrong one, so date-range filtering is dropped rather than fixed — the same reasoning already documented above for get_reader_access_history.

get_access_history and get_card_access_details both also accept RESOLVEDESCRIPTIONS (default true — on by default; the same opt-out default as get_reader_access_history's own RESOLVEDESCRIPTIONS above, and unlike RESOLVENAMES, which defaults to off): unless explicitly set to false, each returned record is enriched with the reader's human-readable READERDESCRIPTION alongside its existing READER (or PORTALNAME, for get_card_access_details) code, preserving every other field. Both tools share the same src/readerDescriptions.ts helper get_reader_access_history uses. It defaults to on rather than off because, unlike person-name enrichment, the underlying GetReaders fetch has a fixed cost — this controller's entire reader table (68 readers) fetches in exactly 2 paginated calls regardless of how many result records are returned, so there's no scaling cost to make callers opt in to. Set RESOLVEDESCRIPTIONS: false to skip the GetReaders call and get the plain (unenriched) response. On both get_access_history and get_card_access_details, RESOLVENAMES and RESOLVEDESCRIPTIONS are independent flags — either, both, or neither may be requested in the same call.

get_card_access_details also accepts its own RESOLVENAMES: true (default false), enriching the response with the card owner's FIRSTNAME/LASTNAME/FULLNAME/NOTES via the same shared src/personEnrichment.ts helper get_access_history uses. Unlike get_access_history (whose response can carry many distinct PERSONIDs, one per record), GetCardAccessDetails' response carries exactly one PERSONID at the top level — a card belongs to one person — so this costs a single GetPerson call per tool call, not one per distinct person. The four enrichment fields land on the top level of the response, alongside PERSONID/DISABLED/EXPDATE, rather than being duplicated onto every ACCESS record.

get_access_level accepts RESOLVEGROUPNAMES (default true — on by default, the same opt-out default as the other RESOLVE* flags above, since GetAccessLevel carries exactly one TIMESPECGROUPKEY and one READERGROUPKEY per call, so resolving both always costs exactly one fixed-size GetTimeSpecGroups fetch and one fixed-size GetReaderGroups fetch, never scaling with anything): unless explicitly set to false, it resolves the response's bare TIMESPECGROUPKEY/READERGROUPKEY foreign keys into new sibling TIMESPECGROUPNAME/READERGROUPNAME fields, using the new src/timeSpecGroupNames.ts/src/readerGroupNames.ts helpers. TIMESPECGROUPKEY is resolved via the full paginated GetTimeSpecGroups list, filtering client-side for the matching key — never the singular GetTimeSpecGroup command, which is verified broken on this controller: it returns CODE=FAIL/ERRMSG="NOT FOUND" even for a genuinely existing group (the same finding already documented for src/unlockWindow/managed.ts). READERGROUPKEY is resolved the same way, via the full paginated GetReaderGroups list, for consistency. An empty/absent key on either axis independently skips that axis's fetch and yields '' for just that axis's name, without affecting the other. THREATLEVELGROUPKEY is never resolved and is left exactly as-is — no NBAPI read command for threat level groups exists in this server's command surface at all. If the underlying GetTimeSpecGroups/GetReaderGroups fetch itself fails, that axis's name resolves to '' and the call still succeeds with the primary GetAccessLevel data intact — an enrichment failure never loses the primary data. Set RESOLVEGROUPNAMES: false to skip both fetches and get the response back exactly as GetAccessLevel provides it.

get_portal_group accepts the same RESOLVEGROUPNAMES flag (default true, same opt-out default and identical kind of lookup as get_access_level's own RESOLVEGROUPNAMES above): unless explicitly set to false, it resolves the response's bare UNLOCKTIMESPECGROUPKEY foreign key into a new sibling UNLOCKTIMESPECGROUPNAME field, reusing the same src/timeSpecGroupNames.ts helper (and so the same full-paginated-list resolution, never the broken singular GetTimeSpecGroup command). A single GetPortalGroup response carries exactly one UNLOCKTIMESPECGROUPKEY, so this always costs exactly one fixed-size GetTimeSpecGroups fetch, never scaling with anything. The already-human-readable PORTALS sub-list ({PORTALKEY, NAME} per portal) is left completely unchanged. THREATLEVELGROUPKEY is never resolved — no NBAPI read command for threat level groups exists in this server's command surface. An empty/absent UNLOCKTIMESPECGROUPKEY skips the fetch entirely and yields '' for the name; if the underlying GetTimeSpecGroups fetch itself fails, UNLOCKTIMESPECGROUPNAME resolves to '' and the call still succeeds with the primary GetPortalGroup data (including PORTALS) intact. Set RESOLVEGROUPNAMES: false to skip the fetch and get the response back exactly as GetPortalGroup provides it.

get_portal_groups accepts the same RESOLVEGROUPNAMES flag (default true, same opt-out default and field name as the singular get_portal_group above — this is its explicitly-planned follow-on): unless explicitly set to false, it resolves every returned group's bare UNLOCKTIMESPECGROUPKEY foreign key into a new sibling UNLOCKTIMESPECGROUPNAME field, reusing the same src/timeSpecGroupNames.ts helper. Unlike the singular tool (whose response carries exactly one UNLOCKTIMESPECGROUPKEY, so it does at most one conditional fetch), this plural tool builds the fetchTimeSpecGroupNames map once per call — only if at least one group on the page carries a non-empty UNLOCKTIMESPECGROUPKEY (zero GetTimeSpecGroups calls if every group's key on the page is empty) — then looks every group up against that same shared map, the same one-fetch-per- page cost shape as get_time_spec_groups's own RESOLVEMEMBERNAMES above, never one fetch per group. Unlike GetPortalGroup (singular), GetPortalGroups' response is already flat per item — DETAILS.PORTALGROUPS.PORTALGROUP[], no per-item PORTALGROUP wrapper — so no per-item unwrap is applied; that wrapper quirk belongs only to the singular command's own response envelope. The already-human-readable PORTALS sub-list ({PORTALKEY, NAME} per portal) is left completely unchanged on every group. THREATLEVELGROUPKEY is never resolved — no NBAPI read command for threat level groups exists in this server's command surface. A group with an empty/absent UNLOCKTIMESPECGROUPKEY gets UNLOCKTIMESPECGROUPNAME: '' without needing a match; a group whose key has no match in the fetched map also gets ''. If the underlying GetTimeSpecGroups fetch itself fails, every group's UNLOCKTIMESPECGROUPNAME resolves to '' and the call still succeeds with every group's other fields (including PORTALS) intact — an enrichment failure never loses the primary data. Set RESOLVEGROUPNAMES: false to skip the fetch and get groups back exactly as GetPortalGroups provides them.

list_events accepts RESOLVEPARTITIONNAMES (default true — on by default, the same opt-out default as the other RESOLVE* flags above): unless explicitly set to false, each returned event's bare PARTITIONID is resolved into a new sibling PARTITIONNAME field via one GetPartitions fetch per call — not per event, since GetPartitions takes no STARTFROMKEY at all and always answers every partition in a single response, so the cost never scales with how many events come back. This is backed by the new src/partitionNames.ts helper, mirroring src/readerDescriptions.ts's shape exactly (a Map-returning fetch function that never throws). An event whose PARTITIONID has no match in the fetched map resolves to PARTITIONNAME: '', and if the underlying GetPartitions fetch itself fails, every event's PARTITIONNAME resolves to '' and the call still succeeds with every other field (including ACTIONS) intact — an enrichment failure never loses the primary data. Set RESOLVEPARTITIONNAMES: false to skip the GetPartitions call and get the response back exactly as ListEvents provides it.

get_time_spec_groups accepts RESOLVEMEMBERNAMES (default true — on by default, the same opt-out default as the other RESOLVE* flags above, since resolving every group's members on a page always costs exactly one fixed-size GetTimeSpecs fetch, never scaling with how many groups/members are on the page): unless explicitly set to false, each group's TIMESPECKEYS.TIMESPECKEY field — which GetTimeSpecGroups returns as bare TIMESPECKEY string(s) — is replaced with a list of {TIMESPECKEY, NAME} objects, matching this codebase's own convention for other group-membership sub-lists that NBAPI already returns as objects natively (get_access_level_group's ACCESSLEVELS, get_reader_group's READERS). A member key with no match in the fetched GetTimeSpecs table (an unknown/deleted time spec) resolves to NAME: '' rather than being omitted. Every other field (TIMESPECGROUPKEY, the group's own NAME, DESCRIPTION) is unchanged. The name lookup uses the new src/timeSpecNames.ts helper — one full paginated GetTimeSpecs fetch per call, regardless of how many groups/members are on the page — and reuses keyList (src/paging.ts, relocated from src/unlockWindow/managed.ts) to normalize the bare-key collection. If the underlying GetTimeSpecs fetch itself fails, every member's NAME resolves to '' and the call still succeeds with every group's own fields intact — an enrichment failure never loses the primary data. RESOLVEMEMBERNAMES applies only to this plural tool, not the singular get_time_spec_group, which is verified broken (CODE=FAIL/ERRMSG="NOT FOUND") on this controller even for a genuinely existing group, independent of this change. Set RESOLVEMEMBERNAMES: false to skip the fetch and get TIMESPECKEYS back exactly as GetTimeSpecGroups provides it (bare string or array of strings).

Write tools and Destructive tools

write (needs only NETBOX_ENABLE_WRITES) and destructive (needs NETBOX_ENABLE_WRITES and NETBOX_ENABLE_DESTRUCTIVE). Every write tool's input schema declares exactly the documented PARAMS fields for its command, matching required/optional as documented — see the "Write access" section above for the gating rules and the shared SUCCESS/WRITE:/ DESTRUCTIVE: conventions.
