Schema Quality & AI Usability63
- AI-judged instruction clarity (good).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

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.

What is the Cursor Delegate MCP server?
Cursor Delegate is an MCP server listed in the public MCP registry as io.github.andreilungeanu/cursor-delegate-mcp. Bridge AI coding hosts to cursor-agent over the Agent Client Protocol. This page covers its npm package (cursor-delegate-mcp).
Is the Cursor Delegate MCP server safe to use?
Cursor Delegate scores 93 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 2026. It declares no install or post-install scripts. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the Cursor Delegate MCP server expose?
Cursor Delegate exposes 3 tools: delegate, cancel, doctor. Their descriptions and schemas cost roughly 617 tokens of context every time the server is loaded.
Is the Cursor Delegate MCP server still maintained?
Cursor Delegate is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
What licence is the Cursor Delegate MCP server under?
Cursor Delegate declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
What did VerifyMCP test on the Cursor Delegate MCP server?
VerifyMCP ran 16 checks on Cursor Delegate, covering Malware scan, Known CVEs, Install scripts, Dependency health and 12 more. Endpoint Security and Transport & Reachability do not apply to an npm package, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
