Pincushion

Pincushion

Teammates and clients pin feedback on your live app in Pincushion. Each pin is a work packet for your coding agent: page URL, CSS selector, screenshot, DOM snippet, viewport and the comment thread. This repository is the install source for the Claude Code, Cursor and Codex plugins and the MCP registry metadata for pincushion-mcp (npm 1.12.5).

Requires Node.js 22.22 or newer, or Node.js 24. Do not put a license key in any MCP config. Sign-in writes ~/.pincushion/license-key for you.

Quick start

Claude Code

claude plugin marketplace add jcooley8/pincushion-plugin

claude plugin install pincushion@pincushion

Codex uses the same marketplace: codex plugin marketplace add jcooley8/pincushion-plugin, then enable Pincushion from the Plugins list.

Start Claude Code in your app's repository. Run /setup, or run the sign-in command in First steps. Then /pins lists open feedback and /critique https://your-site.example runs a Pincushion crit of that URL.

Cursor

Add Pincushion to Cursor.

That deeplink installs npx -y pincushion-mcp over stdio and does not set a license key. Restart Cursor in your app's repository, then follow First steps. /pins and /critique ship with the Cursor plugin in this repository.

VS Code

code --install-extension pincushion.pincushion-feedback

Or install Pincushion Feedback from the Marketplace. Reload the window in your app's repository, then follow First steps.

To add the server without the extension, put this in .vscode/mcp.json:

{

"servers": { "pincushion": { "command": "npx", "args": ["-y", "pincushion-mcp@latest"] } } }

Cline

Add the pincushion entry from llms-install.md to cline_mcp_settings.json. It is npx -y pincushion-mcp@latest over stdio, with no API key. Pin reads work before sign-in. The same page has the sign-in command.

Any other MCP client

Add this stdio server. Start the client in your app's repository so the server's working directory is that repo. If the client starts somewhere else, append "--project-dir" and the absolute path of the repo to args.

{

"mcpServers": { "pincushion": { "command": "npx", "args": ["-y", "pincushion-mcp@latest"] } } }

First steps

In your app's repository, run:

npx -y pincushion-mcp setup

Setup opens a browser, signs you in, and links the repository to a Pincushion project. Restart the client, then ask: "show my open Pincushion pins."

Before that sign-in the server still starts. get_actionable_pins, get_annotations and get_feedback_summary read pins in this repo's .feedback/ directory, and an empty workspace includes a sample pin that is not saved to your project. claim_pin, fix_and_resolve, cloud pins and critiques need the setup sign-in.

The Pincushion browser extension is optional. Pins can come from shared review links, Pincushion AI critiques, other agents and the REST API.
