Watchgoose

Watchgoose MCP

Watchgoose MCP connects MCP-capable AI clients to the Watchgoose Management API. It lets you inspect cron and recurring-task monitoring, with check changes available only when you explicitly enable writes.

Hosted connector

Use the hosted Streamable HTTP endpoint in clients that support OAuth 2.1 and Dynamic Client Registration:

https://mcp.watchgoose.com/mcp

Available in

Watchgoose is available in the Claude connector directory.

Watchgoose is listed in ChatGPT plugins for GPT and Codex.

Watchgoose is listed in the official MCP Registry.

The watchgoose-mcp package is available on npm.

In Claude, open Settings > Connectors and add the endpoint as a custom connector. For Claude Code, run:

claude mcp add --transport http --scope user watchgoose https://mcp.watchgoose.com/mcp

The browser consent flow limits each connection to one project and defaults to read-only access. See the Watchgoose MCP documentation for the tool and privacy boundaries.

Requirements

• Node.js 20 or later
• A project-scoped Watchgoose API key from Project settings → API Access → Create (read-only)

Use an hcr_ read-only key when you only need check state and status history. Use an hcw_ read-write key when you also need pings, integrations, or check changes.

Claude Desktop

Add this entry to claude_desktop_config.json and restart Claude Desktop:

{
  "mcpServers": {
    "watchgoose": {
      "command": "npx",
      "args": ["-y", "watchgoose-mcp"],
      "env": {
        "WATCHGOOSE_API_KEY": "hcr_your_project_key"
      }
    }
  }
}

Claude Code

claude mcp add --env WATCHGOOSE_API_KEY=hcr_your_project_key \
  --transport stdio --scope user watchgoose -- npx -y watchgoose-mcp

Run claude mcp get watchgoose to check the connection.

Cursor

Create .cursor/mcp.json in your project, or add the same entry to your user MCP configuration:

{
  "mcpServers": {
    "watchgoose": {
      "command": "npx",
      "args": ["-y", "watchgoose-mcp"],
      "env": {
        "WATCHGOOSE_API_KEY": "hcr_your_project_key"
      }
    }
  }
}

VS Code

Create .vscode/mcp.json:

{
  "servers": {
    "watchgoose": {
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "watchgoose-mcp"],
      "env": {
        "WATCHGOOSE_API_KEY": "hcr_your_project_key"
      }
    }
  }
}

Run MCP: List Servers and start watchgoose.

Environment

Variable	Required	Default	Description
WATCHGOOSE_API_KEY	Yes	-	Project-scoped hcr_ read-only key, hcw_ read-write key, or legacy 32-character key.
WATCHGOOSE_API_URL	No	https://watchgoose.com/api/v3	Management API base URL. HTTPS is required except for loopback development hosts. The key is sent to this host, so use only a URL you trust.
WATCHGOOSE_ENABLE_WRITES	No	false	Set to true to expose mutation tools when the key is read-write.
WATCHGOOSE_API_KEY_ACCESS	Legacy keys only	-	Required as read-only or read-write for an unprefixed 32-character key.

The server classifies key prefixes locally and never probes the API to infer access. Setting WATCHGOOSE_ENABLE_WRITES=true cannot give a read-only key additional access.

Tools

Checks are addressed by stable 40-character unique_key values. UUIDs, ping URLs, and integration UUIDs are used only inside the server and are not shown to the AI client.

Tool	Required access	Management API mapping
list_checks	Read-only	GET /checks/
get_check	Read-only	GET /checks/<unique_key>
list_flips	Read-only	GET /checks/<unique_key>/flips/
list_pings	Read-write	Resolve unique_key, then GET /checks/<uuid>/pings/
list_channels	Read-write	GET /channels/
create_check	Read-write plus writes enabled	POST /checks/
update_check	Read-write plus writes enabled	Resolve unique_key, then POST /checks/<uuid>
pause_check	Read-write plus writes enabled	Resolve unique_key, then POST /checks/<uuid>/pause
resume_check	Read-write plus writes enabled	Resolve unique_key, then POST /checks/<uuid>/resume
delete_check	Read-write plus writes enabled	Resolve unique_key, then DELETE /checks/<uuid>

Integration assignments use exact integration names. Names must be non-empty and unique within the project.

List results are capped at 100 checks, 100 pings, 200 flips, and 100 integrations. Every serialized tool result is also capped at 24,000 characters. Results include metadata when entries are omitted.

Security

• Writes are disabled by default, even with an hcw_ key.
• The API key is sent only in the X-Api-Key header and is never logged or returned.
• API redirects are rejected so credentials cannot be forwarded to another host.
• Check UUIDs, ping and update URLs, integration UUIDs, and unknown future API fields are removed from output.
• Pings keep only type, date, n, scheme, method, and duration. Source IP addresses, user agents, run IDs, and body URLs are removed.
• Ping bodies are never requested.
• The server has no telemetry.

Protect client configuration files that contain API keys. Prefer a dedicated project and the least-privileged key that exposes the tools you need. Revoke a key from Watchgoose project settings when it is no longer in use.

Development

npm install
npm run format:check
npm run lint
npm run typecheck
npm test
npm run publish:dry-run

Production integration tests are opt-in and require dedicated test-project keys. They never run in CI.
