Set up Convex MCP in Cursor

Introspect tables, call functions, read and write data, manage environment variables, and view logs on your Convex reactive backend.

Locate the config file

Cursor reads MCP server configuration from the following file:

.cursor/mcp.json

Create this file if it does not already exist.

Add the configuration

Add the following to your Cursor config file:

json

{
  "mcpServers": {
    "convex-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "convex@latest",
        "mcp",
        "start"
      ]
    }
  }
}

Set up environment variables

No environment variables needed. Convex MCP works out of the box without any API keys or tokens.

Verify it works

Restart Cursor. Convex MCP should appear in your MCP server list with 12 tools available.

This server adds approximately 6,180 tokens to your context window for tool definitions.
