How to connect Fine Structure to Cursor with MCP

Cursor can work with Fine Structure through an mcp.json file in the project or through a global configuration.

Cursor is a good fit for anyone already working inside a code editor who wants to connect Fine Structure to the same workflow. Once connected, you can ask Cursor to edit an app created in Fine Structure using the platform's official tools.

For a single project: Create .cursor/mcp.json inside the project. This is good when you don't want the connection to show up everywhere.

For all projects: Create ~/.cursor/mcp.json. This is good for anyone who works with Fine Structure regularly.

Remote MCP: The connection uses the address https://finestructure.ai/api/mcp and an Authorization header.

Token first, then Cursor

Without an MCP token, Cursor has no safe way to identify you to Fine Structure.

Steps

• Sign in to your Fine Structure account.
• Open the MCP page using the Create MCP token button in the docs, or go directly to /mcp.
• Choose whether the agent gets access to all the apps you own or to a single app only.
• Choose permissions: Read only for testing, Build for editing, Full access only for an agent you trust.
• Click Create MCP setup and copy the token or the configuration block. The token is shown only once.
• Open or create a .cursor/mcp.json file in the project.
• Paste the config below and replace the token.
• Refresh MCP in Cursor or reopen the editor.
• Ask Cursor to use the Fine Structure MCP and call get_platform_guide.

{
  "mcpServers": {
    "fine-structure": {
      "type": "http",
      "url": "https://finestructure.ai/api/mcp",
      "headers": {
        "Authorization": "Bearer fse2_mcp_<token>"
      }
    }
  }
}

Recommended wording for the first request

• Use the Fine Structure MCP server.
• Call get_platform_guide first.
• List my apps, then ask me which app to work on before making changes.
