## MCP tools (3)

### `delegate` (~348 tokens)

Send a prompt to Cursor Agent and wait until that Cursor turn is terminal, including tool work and any sub-agent follow-up Cursor performs before it stops. Returns Cursor's reply and the sessionId to reuse. A second call for a session that is still running is rejected. You decide CONTINUE, COMPLETE, or BLOCKED. Do not shell out to the agent binary.

Input parameters:

- `context` (string): Context-window option when the model advertises one, such as 272k or 1m. Omit unless the user asks.
- `contextFiles` (array): Files to attach. Text becomes resource links. Images (png, jpg, gif, webp, under 5MB) are sent inline when Cursor accepts them. Missing files are warnings, not failures.
- `effort` (string): Exact effort value advertised by the selected model. Invalid values fail before the prompt and name the accepted set.
- `fast` (boolean): Request Cursor's fast tier. Leave false unless the user asks. Higher cost.
- `mode` (string): agent implements. plan asks Cursor to produce a plan and stop. ask is for a read-oriented question. The mode is an instruction to Cursor.
- `model` (string): Optional Cursor model id. Omit to keep Cursor's current default.
- `prompt` (string, required): Natural prompt for Cursor. Sent as written. Point at files and project documents instead of pasting them.
- `sessionId` (string): Resume this Cursor session. Omit to start one. Use the sessionId from the previous result for follow-up work.
- `workspace` (string, required): Existing project directory Cursor will work in. Must not be the home directory or filesystem root.

### `cancel` (~77 tokens)

Cancel an in-flight Cursor turn by sessionId. Status is cancelled, killed, not-running (the turn ended and the session can still be resumed), or not-found.

Input parameters:

- `force` (boolean): After a short grace period, kill the Cursor process if the turn is still running.
- `sessionId` (string, required): Session id returned by delegate.

### `doctor` (~70 tokens)

Report Node, bridge version, Cursor CLI discovery, authentication state without secrets, and an optional ACP handshake.

Input parameters:

- `deep` (boolean): Open a short ACP session to verify Cursor can start. This creates an empty Cursor session.
- `workspace` (string): Optional project directory to validate and scan for project context files.
