Pincushion gives you design feedback on your live app that your coding agent can act on. Clients, teammates, or your designer friend drop pins on any element — free, no setup — and each pin carries selector, screenshot, viewport, thread, and project context. Your coding agent (Cursor, Claude Code, Codex) lands the change in your IDE via an MCP server.

How does Pincushion work with AI agents?

Pincushion includes an MCP server that connects to AI coding agents like Claude Code, Cursor, and VS Code Copilot. Agents can read feedback pins, claim them, implement the code change, and resolve them — all without manual ticket management.

Yes. The Free tier includes 1 project with unlimited pins, full MCP integration, and open commenting. Pro ($19/mo) adds unlimited projects, Realtime sync, and access controls — lock pins to a company domain or require an invite. Team ($49/mo) adds 3 seats and team collaboration.

What is an agent work packet?

An agent work packet is a Pincushion pin that carries everything a coding agent needs to land the fix in one MCP call: CSS selector, surrounding DOM snippet, screenshot, viewport size at pin-drop time, comment thread, project context, and optional acceptance criteria. The pin is the spec — your agent doesn't need a separate ticket or a manual prompt.

What is post-deploy verification?

When a deploy ships pins that were resolved by your agent, Pincushion AI revisits the page in your next IDE session and writes back a verdict — verified, regressed, or inconclusive — directly onto each pin. Stakeholders see the verdict on the pin so they know the fix actually landed correctly. Available on Pro and Team plans.

How fast does Pincushion ship feedback?

Pincushion tracks time-to-fix — the duration from pin drop to pin resolution — and surfaces median, p25, and p75 to Pro and Team accounts. The metric needs at least 5 resolved pins before it renders, so the number is never a single-pin lie. The aggregate across all Pincushion users is on the landing page when the dataset is meaningful.

Point. Pin. Fixed.

You shipped the app. Now get design feedback you can actually act on — your client, teammate, or designer friend drops a pin on the live thing, and it lands in your IDE with the selector, screenshot, and thread your agent needs to fix it. Reviewers are always free. No seats, no setup, nothing to install on their end.

Pin feedback

AI reads & ships

Resolved

Features

The feedback loop,
finally closed.

Agent slash commands

Type /pins, /my-pins, or /resolve in any supported IDE and your agent instantly pulls the relevant feedback and acts on it. Works in Claude Code, Cursor, VS Code, Windsurf, and Antigravity — zero extra config.

MCP agent integration

One command: npx pincushion-mcp. Your AI reads pins, claims them, writes the change, and resolves — all via Model Context Protocol.

Pincushion AI

An AI teammate, free on every plan. Run /critique and Pincushion AI drops UI/copy/a11y pins on your page. Mention @pincushion in any thread for a follow-up. Runs in your IDE on your tokens — page analysis and model execution stay local; resulting pins sync like any human pin.

Roles & permissions

Owners, developers, and commenters — each with exactly the right level of access. Commenters are always free. You only pay for developers.

Pin any element

CSS selectors, XPath, visual coords — all captured automatically. Works on any site.

Threaded comments

Inline discussions right on the element. Context stays where it belongs.

An agent work packet, not a feedback item

Other tools hand feedback to developers. Pincushion hands it to your coding agent — selector, DOM snippet, screenshot, viewport, thread, project context, and acceptance criteria, all in one MCP call. Resolved pins keep the commit SHA, branch, and PR URL attached to the implementation record.

Slack & Teams notifications

Pipe pin activity into the channels your team already lives in. Subscribe to ready-for-dev pins, @-mentions, and follow-up replies — or opt in to every new pin and resolved change. Per-page filters, named subscriptions, one-click OAuth install.

Chrome & every MCP editor

Chrome extension for stakeholders. MCP integration + VS Code marketplace extension for Cursor, Claude Code, VS Code, Windsurf, and Antigravity. Real-time cloud sync keeps everyone on the same page. Works on production, localhost, staging — if it renders in a browser, you can pin it.

Developer Setup

Connect your agent.

Pick your editor. pincushion's MCP server works with any agent that supports Model Context Protocol.

VS Code & Cursor extension

VSIX install

The Pincushion extension auto-configures the MCP server and adds @pincushion as a Copilot Chat participant — works in both VS Code and Cursor.

Download VSIX (v0.2.0)

After downloading, run code --install-extension pincushion-feedback-0.2.0.vsix (or drag the file into Extensions → Install from VSIX…). Marketplace listing also pending — VSIX is the canonical install for now.

Available commands after install: @pincushion /pins — show all open feedback
@pincushion /my-pins @you — your @mentioned pins
@pincushion /resolve <id> — claim & close a pin
@pincushion /feedback-summary — project overview
@pincushion /implement — run the full approved-pin loop

Plus deploy-time AI critique via the deploy webhook — runs /critique on every push and auto-resolves landed pins.

Cursor

Marketplace

Install the MCP server with one click via the Cursor deeplink — the bundled Marketplace listing is still pending review.

Add Pincushion MCP to Cursor Install from Cursor Marketplace Coming soon

Or add manually to ~/.cursor/mcp.json:

{ "mcpServers": { "pincushion": { "command": "npx", "args": ["pincushion-mcp", "--project-dir", "."] } } }

Claude Code

1 command

Run this once in your project root. Claude Code registers pincushion as an MCP server automatically.

# run in your project root claude mcp add pincushion -- npx pincushion-mcp --project-dir .

After adding, prompt your agent: "Check pincushion for open feedback" — it will call get_actionable_pins and start working.

Claude Desktop

Config file

Add to claude_desktop_config.json. On macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

{ "mcpServers": { "pincushion": { "command": "npx", "args": [ "pincushion-mcp", "--project-dir", "/absolute/path/to/project" ] } } }

Replace /absolute/path/to/project with your repo path. Restart Claude Desktop after saving.

Windsurf

Config file

Open Windsurf → Preferences → MCP, or edit ~/.windsurf/mcp.json directly.

{ "mcpServers": { "pincushion": { "command": "npx", "args": ["pincushion-mcp", "--project-dir", "."] } } }

Antigravity

Config file

Add to your Antigravity MCP config file. Use . for the project dir if running from your repo root, or provide an absolute path.

{ "mcpServers": { "pincushion": { "command": "npx", "args": ["pincushion-mcp", "--project-dir", "."] } } }

Any MCP Client

npx

Any editor or agent runtime with MCP support can connect using npx. Point --project-dir at your repo root.

# command npx pincushion-mcp --project-dir /path/to/repo # optional: cloud sync (requires license key) # env: PINCUSHION_LICENSE_KEY=your_key

How roles work: Developers connect their AI agent via MCP, use slash commands, claim pins, and ship the changes. Free tier covers one project with no usage caps — upgrade for unlimited projects and Realtime sync. Stakeholders (designers, PMs, clients) drop pins, leave comments, and participate in threads — completely free, no seat required, ever. The people creating feedback never hit a paywall. You only pay for the developers whose agents do the work.
