MCP Setup

Connect the feedback surface to your coding agent.

Pincushion’s MCP server reads project feedback, exposes a stable tool surface to your IDE, and keeps the feedback thread attached to the code change. Start with the wizard to register the project and explicitly choose your editor; a written config still needs an editor restart and a real pin read.

These are the launch-ready entry points surfaced by the repo today.

IDE How to connect Config surface
Claude Code Use the wizard or run the one-liner in your repo root. claude mcp add pincushion -- npx pincushion-mcp --project-dir .
Cursor The wizard writes the project config after an explicit Cursor choice. .cursor/mcp.json
VS Code The wizard writes the project config after an explicit VS Code choice. .vscode/mcp.json
Codex CLI Run the Codex-managed command in your repo root. codex mcp add pincushion -- npx pincushion-mcp --project-dir .
Windsurf Choose Manual in the wizard, then use Windsurf’s own MCP instructions. Manual fallback
Antigravity Choose Manual in the wizard, then use Antigravity’s MCP instructions. Manual fallback

Config examples

Remote MCP URL

{
  "mcpServers": {
    "pincushion": {
      "type": "streamable-http",
      "url": "PASTE_SIGNED_IN_REMOTE_URL"
    }
  }
}

The hosted URL works with cloud-synced pins, critique pins, page snapshots, share reports, and thread/status updates. Use the local server below when the agent needs repo files, git history, the quickstart demo, or the localhost browser bridge.

After the wizard signs you in, run npx pincushion-mcp remote-url if your MCP client only accepts a server URL. Paste its output rather than manually entering a license key, and treat that full URL as a secret.

Claude Code

claude mcp add pincushion -- npx pincushion-mcp --project-dir .

Codex CLI

codex mcp add pincushion -- npx pincushion-mcp --project-dir .

Cursor

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

VS Code

File: .vscode/mcp.json

{
  "servers": {
    "pincushion": {
      "command": "npx",
      "args": ["pincushion-mcp", "--project-dir", "${workspaceFolder}"]
    }
  }
}

After connection

Configuration is only the first step. Restart the selected editor and read a real pin before treating the agent as connected.

Register URLs

Run npx pincushion-mcp setup and accept or edit the local and deployed URLs. For a report, use npx pincushion-mcp claim <report-token>.

Verify feedback access

Start with get_actionable_pins after restart. That real read confirms access; config written alone does not.

Work one approved finding

Review an existing AI or human finding, approve that exact pin, then use claim_pin and fix_and_resolve after the code change.

Troubleshooting

  • If the extension does not appear on your site, make sure the project URLs were registered and that you are not on a Chrome-internal page.
  • If the agent cannot see pins, verify the MCP server is running and start with get_feedback_summary.
  • If you need human help, email support@pincushion.io.
