Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
How do I install the Cursor Delegate MCP server?
Cursor Delegate runs locally as an npm package, launched with npx -y cursor-delegate-mcp. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
cancel ~109
Best-effort cancel of an in-flight delegation by sessionId. session/cancel is advisory — the agent may finish the turn anyway, and the delegate result then carries cancelRequested. Status: cancelled, killed (agent process observed to exit), not-running (turn already ended, still resumable), not-found (id not in this process's recent session history).
| Name | Type | Req | Description |
|---|---|---|---|
| force | boolean | – | Kill the agent process if the turn is still running after a short grace period. |
| sessionId | string | yes | – |
No output schema declared.
No examples provided.
delegate ~439
Delegate a coding task to cursor-agent over ACP. Never shell out to cursor-agent — use this tool only. Auto-approves every permission the agent requests, in any mode and anywhere on disk. Clarifying questions arrive as prose in result — resume with resumeSessionId to answer. Keep model (composer-2.5), fast and effort at their defaults unless the user explicitly asks. See the delegate skill.
| Name | Type | Req | Description |
|---|---|---|---|
| context | string | – | Context window size; gpt-5.x accepts 272k and 1m. Do not pass speculatively. |
| contextFiles | array | – | Paths to attach instead of pasting contents into spec. Text becomes references the agent may open; images (png/jpg/gif/webp, <5MB) are sent inline. Relative paths resolve against workspace but are no… |
| effort | string | – | Exact Cursor thinking-effort value for the selected model. Values differ per model and some expose no effort option; invalid values fail before the prompt and name the accepted set. Pass only when th… |
| fast | boolean | – | Fast tier; higher cost — only when the user asks. |
| mode | string | – | agent implements; plan and ask are instructions to the agent, not limits. |
| model | string | – | Bare ACP family id, version included: composer-2.5, grok-4.5, claude-opus-5, gpt-5.6-sol. doctor deep:true lists every id. |
| resumeSessionId | string | – | Continue an existing ACP session. |
| spec | string | yes | Task brief: goal, scope, fixed decisions quoted exactly, acceptance criteria. Sent as written. Point at files to read rather than pasting code, or attach them with contextFiles. |
| workspace | string | yes | The agent's working directory, not a limit. Smallest directory holding the task's files; with no such directory the project root is the floor. Must already exist; never create one for the call. |
No output schema declared.
No examples provided.
doctor ~69
Setup diagnostics: plugin version, MCP client capabilities, cursor-agent launcher resolution. Run when delegation fails or agent.found is false.
| Name | Type | Req | Description |
|---|---|---|---|
| deep | boolean | – | Run an ACP handshake (start → initialize → newSession) to verify the agent is usable; adds models, modes and the current model's options. |
No output schema declared.
No examples provided.
