Point. Pin. Fixed.

Your client, teammate, or designer drops a pin on your live web app — or on a mobile crit wall generated from native app screens. Your coding agent (Cursor, Claude Code, Codex, Windsurf) reads it and ships the fix, with the selector or hotspot, screenshot, and thread in one MCP call. Reviewers are always free, nothing to install on their end.

We'll email you the Chrome install link

✦ Every account starts with 14 days of Pro — realtime sync & unlimited AI actions, no card. Then free forever: 1 project, unlimited manual pins, 25 AI actions/mo.

Four steps.
Zero friction.

Anyone drops a pin

Your reviewer — client, teammate, designer friend — right-clicks any element on the live web app and types a note. For native iOS apps, generate a mobile crit wall from simulator screens so they can comment on the flow in a browser. No account dance, no paid seat, nothing to install on their end. We grab the selector, hotspot, XPath, or coordinates behind the scenes. They can even just email it: a note or screenshot sent to your project's pin+…@in.pincushion.io address becomes a pin too.

Discuss in place

Threaded comments appear right on the page. Context stays where it belongs — not in a Slack thread from last Tuesday.

Your agent picks it up

The pin arrives via MCP in Cursor, Claude Code, Codex, or Windsurf — selector, screenshot, viewport, thread, and project context in one call. No translating screenshots into prompts.

The loop closes

Resolving records the commit, branch, and PR. The deploy hook links the live deploy, and Pincushion AI re-checks the fix on the deployed site — so your reviewer sees their note shipped and verified, not just "marked resolved."

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.

Mobile crit walls

Turn iOS simulator screens into a browser-based critique wall with semantic hotspots. Reviewers comment without installing anything; your agent still gets source hints, screen context, and a repeatable mobile-wall publish refresh path after changes land.

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.

Add to Slack

Share a report, no install

Every project gets a public link at pincushion.io/r/<token>. It's a live screenshot of the page with real pin markers, threads, and status. Anyone with the link can view it, reply, or drop a new pin right in the browser, no extension, no account. Click into a resolved pin to see what the page looked like before, the PR that fixed it, and when it shipped.

Chrome & every MCP editor

Chrome extension for stakeholders who want it installed, or send a share-report link if they'd rather not. MCP integration + a VS Code/Cursor 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.

Plays nice with

Your agent doesn't
just read feedback.

It acts on it. pincushion exposes an MCP server that any agent can connect to. It reads pins, understands context, writes the change, and resolves — without you lifting a finger.

Get Started
// Connect in one command
npx pincushion-mcp --project-dir .

// Agent fetches open feedback
get_feedback_summary()

{
  "pins": [{
    "selector": ".hero > h1",
    "comment": "Change to Welcome Home"
  }]
}

// Agent writes the change & resolves
fix_and_resolve("pin_1", "Updated heading text")  // done

See it on your own page first.

Not ready to wire up your agent? Drop your web URL and Pincushion AI pins concrete UI, copy, and a11y fixes right on your live page. Shipping native mobile? Generate a crit wall from simulator screens and use the same pin-to-agent loop. Keep the pins with a free account and invite your team — nothing to install on anyone's end.

Connect your agent.

Pick your editor. pincushion's MCP server works with any agent that supports Model Context Protocol. On Next.js or Vite? One npm install makes every dev build and preview deploy pinnable — no extension needed for reviewers. Built it with Lovable, Bolt, or v0? One script tag makes the generated app reviewable by anyone.

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", ".", "--cloud-sync"] } } }

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 . --cloud-sync

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", "--cloud-sync" ] } } }

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", ".", "--cloud-sync"] } } }

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", ".", "--cloud-sync"] } } }

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 --cloud-sync # sign in once to link your license: npx pincushion-mcp login # (or set PINCUSHION_LICENSE_KEY=your_key)

For the new era —
when the product is the design.

Design-file comments pincushion
Where you comment A static design file The product you've actually shipped
What you comment on Pixels in a frame Real DOM elements — CSS selector, XPath, coords
Source of truth The design file (drifts from production) The code that's actually running
Who acts on the feedback Designer hands off, developer rebuilds Pin lands in your IDE as agent-ready implementation context
Loop closes when Designer marks the comment resolved The change ships — pin auto-resolves on deploy
Stakeholder cost Paid seat, or heavily limited guest access Always free — no seat, no cap, ever

Design-file comments belong on the file. Pincushion belongs on the live thing — for teams whose design lives in the code.

Three concepts that make the loop close itself.

Agent work packet

More than a screenshot.

Every pin carries the CSS selector, surrounding DOM snippet, viewport size, full comment thread, project context, and optional acceptance criteria — all in one MCP call. Your coding agent gets the same picture you do, without you translating anything into a prompt.

Post-deploy verification

Proof the fix shipped.

When a deploy includes pins your agent resolved, Pincushion AI revisits the page and writes back a verdict — verified, regressed, or inconclusive — directly onto the pin. Stakeholders see proof. Pro & Team.

Time-to-fix

The metric that matters.

Feedback tools brag about how fast they collect bugs. Pincushion brags about how fast bugs close. Median pin-to-PR, with a 5-pin minimum so the number is never a lie. Pro & Team for your projects; aggregate below.
