notes: Official hosted/remote Endgame MCP Server, in open beta and available to all users. Connects AI
  assistants (Claude, ChatGPT, Claude Code, Codex CLI) to the organization's revenue intelligence. Endgame
  states the tool set is discovered per account and changes during beta — clients are told to use "Refresh
  Tools List" — so the tools below are the ones Endgame's own documentation names verbatim, not a complete
  manifest. Live introspection is auth-gated (see probe).
server:
  name: endgame
  transport: http
  url: https://app.endgame.io/api/v1/mcp
  auth: oauth
  auth_detail: OAuth 2.0 against the authorization server advertised at https://app.endgame.io/.well-known/oauth-authorization-server
    (issuer app.endgame.io, endpoints delegated to WorkOS at login.endgame.io). The endpoint is registered
    as an RFC 9728 protected resource. Browser sign-in for assistant connectors; authorization_code or
    device_code for the CLI.
  install:
    claude_code: claude mcp add --transport http endgame https://app.endgame.io/api/v1/mcp
    claude_code_user_scope: claude mcp add --transport http endgame --scope user https://app.endgame.io/api/v1/mcp
    codex: codex mcp add endgame --url https://app.endgame.io/api/v1/mcp
    claude_connector: Add a custom connector in Claude with the URL https://app.endgame.io/api/v1/mcp
      (admin adds it org-wide, each user then connects).
    chatgpt: Create a custom app in ChatGPT with the URL https://app.endgame.io/api/v1/mcp, publish it
      to the org, then each user enables it.

  note: The endpoint is live and correctly implements the MCP authorization spec — it answers with an
    OAuth challenge naming its protected-resource metadata rather than a bare 401. Input schemas for the
    tools below require an authenticated tools/list and are therefore NOT recorded here; nothing is guessed.

related_rest_operations:
- note: None. No documented MCP tool is backed by a public REST operation — the REST API is thread CRUD
    only. See mcp/end-game-tool-crosswalk.yml.
