Docs: Workspace API MCP reference Web App: Workspace managers configure Ponder tool permissions in the Persona editor; standalone MCP hosts use their own tool and confirmation experience. Parable MCP connects assistants and developer tools to Workspace and Admin operations through the same generated contracts used by HTTP and the SDKs. Every Workspace operation has an explicit MCP classification. Most product operations are available to discovery; browser callbacks, secret exchange, machine plumbing, Ponder control-plane routes, and unsupported multipart operations are explicitly hidden. Four schema declarations keep the tool surface understandable:
  • @docs supplies the display title, description, capability, lifecycle, and audience shared across protocol references;
  • @icon supplies the Font Awesome glyph;
  • @mcp supplies the stable lowercase handle, visible-or-hidden decision, and default Ponder policy; and
  • the route’s permission declaration and behavior remain the authority for what a person can read or change.
A catalog entry never grants access. Search omits operations the current person cannot use, and the generated API route checks authentication, permission, resource ownership, state, and revision again when invoked.

Discover tools without loading the whole catalog

Standalone MCP sessions keep environment, Workspace, authentication, and catalog tools available. After authentication:
  1. Search with tool_search. Results contain lightweight titles, descriptions, icons, and handles, not every JSON Schema.
  2. Enable a selected operation with tool_enable.
  3. The session publishes the enabled generated tool and sends notifications/tools/list_changed.
  4. Authentication, logout, Workspace changes, and permission refresh reconcile the session’s enabled tools.
Session activation is isolated: enabling a tool in one MCP connection does not publish it in another. Standalone MCP does not apply Ponder Persona policy; the MCP host owns its confirmation experience. Ponder uses the same Workspace catalog through three internal helpers: search, inspect one exact schema, and execute an inspected operation. It never places the complete catalog in model context. A Persona-wide policy can narrow each operation to Never, Ask, or Always, but that policy cannot grant an operation the initiating person lacks.

Approvals in Ponder

  • Never omits the operation from that Persona’s search.
  • Ask pauses the tool call in the Message and offers Deny once and Allow once.
  • Always continues without a separate Ponder prompt.
Workspace managers can remember Always or Never for the Persona or Workspace default. The policy write must commit before the pending call continues. Signed approval state binds the person, Problem, Message, Persona, execution profile, catalog schema, arguments, and current policy. The accepted model and text configuration are retained across the pause; changing a ranking does not silently switch providers during continuation. The browser receives only a safe title, consequence, bounded summary, and opaque approval identity. HTTP paths, operation IDs, and SDK method names remain independent compatibility identifiers. A tool handle does not rename those surfaces.

Local stdio

The local stdio server keeps authentication and Workspace selection inside the MCP session, then forwards enabled operations through generated SDK dispatch. In a derived worktree it replaces the checked-in development URLs only when both API endpoints resolve from WEB_API_URL and WEB_ADMIN_API_URL, or from the paired WEB_API_PORT and WEB_ADMIN_API_PORT values. A partial or invalid override fails startup instead of mixing services from different checkouts. Source the worktree stamp before running the Vercel AI SDK smoke:
The smoke initializes the real stdio transport and sends a read-only sentinel health call to the worktree Admin API. The session deliberately has no bearer token, so success means the API request occurred and returned the server’s sanitized refusal. The smoke never prints or persists a credential or the underlying API response.
