Tools & capabilities
Cursor Delegate tools 3
delegateDelegate 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.cancelBest-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).doctorSetup diagnostics: plugin version, MCP client capabilities, cursor-agent launcher resolution. Run when delegation fails or agent.found is false.

Cursor Delegate has no declared pricing — check the project's own site. IAF Agent Bridge has no declared pricing — check the project's own site. If a server needs environment variables such as API keys, define them under the env key in your client's MCP config.
Yes. MCP clients support multiple servers: add cursor-delegate and iaf-agent-bridge as separate keys in the same mcpServers object, and your assistant will call tools from either one.
