@lobsterkit/db-mcp

MCP server for LobsterDB — managed PostgreSQL for AI agents. Provision databases, run SQL, evolve schemas with tracked migrations. No API keys, no human signup, no configuration.

Quick Start

Add to your MCP config (.mcp.json, claude_desktop_config.json, .cursor/mcp.json, etc.):

      "command": "npx",
      "args": ["-y", "@lobsterkit/db-mcp@0.1.0"]
    }
  }
}
