  • Sentry MCP
    optionalmcp

    Pull recent frontend errors and connect them to specific commits or components.

What you can do with it

  • Build from Figma

    Read the latest frame from figma "Pricing v3", check our existing Button and Card components in /Users/me/app/src/components, generate the new Pricing page following the same patterns, then open a PR on github.

  • Fix what broke after deploy

    Pull the top 5 frontend errors from sentry in the last 24h, find the components they originate from in /Users/me/app/src, and propose fixes.

  • API contract check

    Fetch /api/v1/users from the staging API, compare the actual response shape to the User TypeScript interface in /Users/me/app/src/types/user.ts, and flag any mismatch.

FAQ — Frontend Engineer (React) Loadout

  • What is the Frontend Engineer (React) Loadout?

    Inspect Figma designs, scaffold components against your real codebase, fetch live data from a staging API, and check Sentry for what broke after the last deploy. Everything a React engineer needs without leaving Cursor. It includes 5 MCP servers: Filesystem MCP Server, GitHub MCP Server, Figma MCP Server, Fetch MCP, Sentry MCP.

  • Does this loadout work with Cursor and Windsurf?

    Yes. The config block above is one JSON object that drops into Claude Desktop's, Cursor's, or Windsurf's MCP config. Each client uses the same mcpServers schema; only the file path differs.

  • How long does setup take?

    About 3 minutes the first time: copy the config, paste it into your client's MCP configuration file, replace placeholder API keys with your own, and restart the client.

  • Can I customise this loadout?

    Yes. Use the Lite version if you want fewer servers, or the Heavy version to add 2 more for advanced workflows. You can also remove any individual server by deleting its entry from the JSON.

  • How much does it cost?

    Loadout itself is free. Most listed servers are open-source and free to run. Servers that talk to paid SaaS (Stripe, SendGrid, Linear, etc.) follow that vendor's pricing.

  • When was this loadout last verified?

    Last verified on 2026-04-24. We re-test featured loadouts at least monthly and update the config when MCP servers ship breaking changes.
