01 · Install GraphQL Enhanced

before you install - you'll need

Set MCP_PORT before connecting. ALLOW_MUTATIONS, ENABLE_HTTP are optional or environment-specific per the README.

Claude Code

claude mcp add letoribo-mcp-graphql-enhanced -- npx -y @letoribo/mcp-graphql-enhanced

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "letoribo-mcp-graphql-enhanced": {
      "command": "npx",
      "args": [
        "-y",
        "@letoribo/mcp-graphql-enhanced"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.
