MCP for Cursor & Claude

Use your Specifys.ai specifications directly inside Cursor and Claude Desktop. The Model Context Protocol (MCP) lets the AI read and update your specs without leaving the editor.

What is MCP and how does it connect to Specifys?

Model Context Protocol (MCP) is an open protocol that lets AI applications talk to external tools and data. Specifys provides an MCP server that exposes your specifications as tools and resources. When you connect Cursor or Claude Desktop to our MCP server with your API key, the AI can list your specs, read any section (overview, technical, design, market), and update content so you can say “use my existing spec” and the assistant has full context.

One API key per user. Create it in Profile and add it to your MCP config.
Works with Cursor and Claude Desktop. Your specs stay in Specifys; the AI accesses them in real time.
Read and update overview, technical, design, and market sections so the AI and your spec stay in sync.

Frequently asked questions

How does this save me time and make work more efficient?

You stop switching between the Specifys site and your editor. The AI has your spec in context instantly, so you can say "build the auth flow from my technical spec" or "update the overview with this change" without copying, pasting, or re-explaining. One source of truth stays in sync whether you edit in the browser or via the AI.

How long does it take to install the MCP system in Cursor or Claude?

About 2-5 minutes. You create an API key in your Profile, add the Specifys MCP server in Cursor (Settings - MCP) or Claude Desktop config, set SPECIFYS_API_KEY, and restart. No extra services or code to run.

Is the system bidirectional? Can I edit the spec on the site through Cursor or Claude?

Yes. MCP supports both read and update. The AI can change the overview, technical, design, market, or architecture sections of a spec via the update tools. Edits made in Cursor or Claude are saved to your spec on Specifys and appear in the Spec Viewer and everywhere else you use that spec.

How do I get an API key?

Sign in, go to Profile - Personal Info - MCP API Key, and click Create API key (or Regenerate). Copy the key once; it is not shown again. Use it as SPECIFYS_API_KEY in your MCP client configuration.
