Analytics - official Statsig server

Statsig MCP server

Hosted MCP server that lets AI clients read and manage Statsig feature gates, experiments, dynamic configs, metrics and audit or Logs Explorer data, with write tools gated by API key permissions and explicit confirmation. Statsig hosts it at https://api.statsig.com/v3/mcp with OAuth or API key auth.

Notes and caveats

  • Current server is V3 at /v3/mcp; the official registry entry still lists https://api.statsig.com/v1/mcp, which the docs file under Legacy V1.
  • OAuth only supports Personal Console API Keys, so an org owner must enable Personal Console API Key creation for the user's role.
  • Alternative auth is a Console API key sent as the statsig-api-key header (docs show it via mcp-remote for Cursor/Codex). 18 default tools, 9 more with expanded tool exposure.
  • No public source repository found.
  • Statsig also runs a separate public, read-only Docs MCP server (get_page, list_pages, search_docs), but its docs page shows the endpoint only as the relative path /api/mcp, so it is not listed as a separate entry.
  • Also offered as a ChatGPT app.
