You prefer local stdio subprocess transport architecture.
Your security boundary fits: No auth required (Free / Open Source).
Access your Apple Books library, annotations, reading progress, and highlights through Claude
Visual feedback as agent work packets. Stakeholders drop pins on your live app; your AI coding agent reads each pin (selector, screenshot, DOM snippet, thread, acceptance criteria) via MCP and ships the fix, recording the commit/branch/PR on resolve. Install: npx pincushion-mcp.
Apple Books is categorized under Developer Tools and uses a local stdio subprocess. In contrast, Pincushion Plugin belongs to Developer Tools using local stdio subprocess. Select Apple Books when you need capabilities focused on developer tools and Pincushion Plugin when you require tools for developer tools.

+18 more tools listed on main page
Pincushion Plugin Tools (12)
get_annotations
Retrieve annotations from `.feedback/`. Filter by page, component, or status.
search_annotations
Full-text search across all annotations, comments, selectors, and tags.
get_feedback_summary
High-level rollup of all feedback: counts by status, priority, page, and component.
get_component_feedback
Get all feedback for a specific LWC component with a plain-language summary.
resolve_annotation
Mark an annotation as resolved after fixing the issue.
add_agent_reply
Add a reply to an annotation thread (e.g., ask clarifying questions).
fix_and_resolve
Combine fixing code and marking an annotation as resolved in one call. Optionally records commit / branch / PR metadata so the dashboard can backlink to what shipped.
get_implementation_packet
Fetch a single implementation packet for one page URL — selector list, full pin payloads, suggested branch name, and traceability config. Use when an agent wants to batch-fix one page in a single branch.
assign_pin_to_agent
Dispatch a pin straight to your local coding agent. Promotes the pin to `ready` if not already, marks `pending_implementation`, and writes a `.feedback/.agent-queue/<id>.json` trigger file that `agent-loop.mjs` picks up and shells out to Cursor / Claude Code / Codex.
link_pin_deploy
Attach a deploy URL to a resolved pin. Typically called by the deploy-hook edge function once production includes the fix, but available manually too.
record_pin_verification
Write Pincushion AI's post-deploy verdict back to the pin. Called by the critic agent after `/critique-latest-deploy` runs against a fresh deploy.
get_time_to_fix_metrics
**Pro/Team feature** — Free callers get sample size + upgrade hint. Median + p25/p75 of pin-to-resolve duration, with a 5-pin minimum so the metric is never noise.
