server:
  name: crossbeam
  transport: http
  remote: true
  endpoint: https://mcp.crossbeam.com/mcp
  access: Remote hosted MCP server. Currently in Limited Availability for Supernode and Enterprise plans,
    by approved domain. Request access via a Crossbeam contact or product@crossbeam.com. Native
    one-click connectors exist for Claude and ChatGPT; custom agents connect via the server URL.
  auth:
    type: oauth2
    note: >-
      Verified live. The endpoint answers an unauthenticated POST with HTTP 401 and
      'WWW-Authenticate: Bearer realm="mcp",
      resource_metadata="https://mcp.crossbeam.com/.well-known/oauth-protected-resource"'
      — RFC 9728 protected-resource discovery. The advertised authorization server is
      mcp.crossbeam.com itself (authorize / oauth/token / register), with jwks_uri on
      auth.crossbeam.com, so the MCP server rides the same identity plane as the REST API.

  Tool names and descriptions are taken from Crossbeam's own help-center article. The live
  tools/list manifest is auth-gated (401), so per-tool inputSchema could not be read; schemas
  require an authenticated introspection. Nothing below is inferred.

  note: >-
    Remote only — Crossbeam ships no stdio package and publishes no npx/pip install. The
    endpoint host resolves to Crossbeam-operated infrastructure (k8s-mcp AWS ELB on
    crossbeam.com) and its protected-resource document self-identifies as
    resource_name "Crossbeam MCP", which is what establishes ownership.
