  Derived by binding the MCP capability list (llms.txt + OAuth protected-resource scopes) to backing
  OpenAPI operationIds in openapi/entergram-openapi.json. The live MCP tools/list is OAuth-gated (401),
  so per-tool inputSchemas were not introspected; bindings are by name/semantics with honest confidence.

  note: >-
    Broadcast/template send is described in llms.txt as an MCP capability; the REST spec exposes
    single-message send but no dedicated broadcast/template operation, so this maps loosely.

  category: custom-fields

mcp_only:
- tool: fire broadcasts from saved templates
  reason: >-
    Saved-template broadcast has no dedicated public REST operation; the MCP tool likely composes
    message sends over a segment server-side.
rest_only:
- reason: >-
    The REST API exposes a much larger surface than the MCP capability summary — workspace/members,
    accounts, groups, custom-column and ticket-custom-column CRUD, webhook management + deliveries,
    media upload tickets, message reactions/forwarding, Make.com webhook integration and resumable
    events — none of which are enumerated as MCP tools in llms.txt.
  operations:
  - get-workspace, get-me, check-workspace-access
  - list-accounts, list-workspace-members, get-workspace-member
  - list-groups, get-group, list-group-members
  - list-custom-columns, create-custom-column, update-custom-column, delete-custom-column
  - list-webhooks, create-webhook, update-webhook, delete-webhook, rotate-webhook-secret, test-webhook, list-webhook-deliveries
  - create-chat-media-upload-tickets, upload-chat-media-bytes, forward-chat-messages, set-chat-message-reactions
  - attachMakeWebhook, detachMakeWebhook, claimMakeWebhookEvent
