Governance for LLM agents: 7 enforced rules + read-only reference tools. Safe in any MCP client.
Deterministic governance lint for MCP server configurations, plus reference tooling for the 7 rules.
| Tool | Does real work? |
|---|---|
audit_mcp_config | Yes. Deterministic lint, zero dependencies, fully offline, never throws. Checks inline secrets in env, shell wrappers, unpinned packages, auto-install flags, broad filesystem scopes, non-TLS remote transports, unpinned docker tags. Returns findings with severities and a 0-100 score. |
check_preflight | Yes, when configured. Reads protected_files_list from nervous-system.config.json or NERVOUS_SYSTEM_PROTECTED_LIST. With no list it says so rather than guessing. If the list is unreadable it FAILS CLOSED. |
get_* (everything else) | No. They return text: the framework, templates, instructions. That is why they are named get_. |
npx mcp-nervous-system
Pass your config as config (object) or config_json (string), e.g. the contents of
claude_desktop_config.json. Returns findings with severities and a 0-100 score.
The write-capable toolset runs server-side and is not in this package.
