Cursor Delegate vs Pincushion Plugin
A side-by-side look at the Cursor Delegate and Pincushion Plugin MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Cursor Delegate for coding agents work as a local process; choose Pincushion Plugin for coding agents as a local process. You can also run both side by side in one mcpServers block.

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.
Pincushion Plugin tools 65
get_annotationsRetrieve annotation pins from the .feedback/ directory. Filter by page URL, LWC component name, or status. Use this to understand what feedback exists before making changes.search_annotationsFull-text search across all annotation comments, selectors, component names, and tags.get_feedback_summaryGet a high-level rollup of all open feedback: counts by status, page, and component. Use this to plan what to address first.get_component_feedbackGet all feedback pins targeting a specific LWC component, with a plain-language summary ready for implementation. Returns element selectors, comments, and thread history.resolve_annotationMark an annotation as resolved after addressing the feedback. Optionally add a resolution comment explaining what was changed.add_agent_replyAdd a reply to an annotation thread (e.g. to ask a clarifying question or note a finding).get_reply_candidatesUsed by /pincushion-replies. Returns pins where Pincushion AI should respond, with each candidate tagged by trigger reason. Two triggers: (a) "mention" — the latest thread message contains @pincushion AND was authored by a human; (b) "reply-on-bot-pin" — the pin was originally authored by Pincushion AI and the latest message is from a human. Skips resolved/archived pins and any pin where the latest message is already bot-authored (idempotency). Newest-first ordering so the slash command can pace replies.add_bot_replyPost a Pincushion AI reply to a pin's thread. Hardcodes author="Pincushion AI" and authorEmail="pincushion-bot@pincushion.io" so the Chrome extension applies bot styling. ONLY call from the /pincushion-replies flow — never as a generic reply. Refuses to post if the latest thread message is already bot-authored (defense-in-depth idempotency).get_pending_critiquesUsed by /critique-latest-deploy. Lists pending critique requests queued by the deploy-hook for the current license. Newer receipts also include a deployment event, prior page outcomes, project-page inventory, and latest per-device capture receipts for truthful local reconciliation before Crit runs. Newest-first. Free on all plans (the gating happened at enqueue time on the deploy-hook side: Pro/Team — including trial-Pro — always enqueue; free licenses enqueue while their monthly AI-action pool has headroom).get_pending_deployment_frame_refreshesLists production deployment frame-refresh work independently of the Critique queue. Use this even when autoCritique is false. The result is redacted: it contains no deployment URL/hash, browser state, storage path, or capture proof. Start a selected run before capturing.start_deployment_capture_runStarts one short-lived local frame-refresh run for an exact deployment and returns its opaque proof once. Keep the proof only in process and pass it to authenticated upload_page_snapshot/record_deployment_page_result/complete_deployment_capture_run calls; never put it in capture-snapshot, shell argv, a report, pin, status message, or file.complete_deployment_capture_runRequests server-side frame-refresh completion after all exact page/device receipts have been recorded. The server rejects missing, stale, replayed, cross-deployment, or expired capture-run evidence and never treats a queue state as a current frame.- +53 more on the listing page

Frequently asked questions
Cursor Delegate is categorized under Coding Agents and uses a local stdio subprocess. Pincushion Plugin belongs to Coding Agents and uses a local stdio subprocess. Pick Cursor Delegate for coding agents work and Pincushion Plugin for coding agents.
Copy the mcpServers block from the config section on this page into your client's config (for example claude_desktop_config.json or ~/.cursor/mcp.json), then fully restart the client.
Cursor Delegate has no declared pricing — check the project's own site. Pincushion Plugin is listed as freemium — a free tier with paid plans. Auth: no auth required. 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 jcooley8-pincushion-plugin as separate keys in the same mcpServers object, and your assistant will call tools from either one.
