Lambda Labs MCP by usefulapi

Lambda Labs MCP by usefulapi

Use your Lambda Labs account from Claude, Cursor, or any MCP client — read GPU instances, instance types, images, filesystems and firewall rules, and launch or terminate instances. Hosted, no local install: connect with your own credentials.

Live endpoint: https://lambda-labs.usefulapi.io/mcp · Homepage: https://usefulapi.io

Connect

• Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://lambda-labs.usefulapi.io/mcp.
• Claude Code: claude mcp add --transport http lambda-labs https://lambda-labs.usefulapi.io/mcp, then run /mcp to log in.
• VS Code: Add to VS Code.
• Cursor and other clients: add the URL as a remote MCP server:

{
  "mcpServers": {
    "lambda-labs": {
      "url": "https://lambda-labs.usefulapi.io/mcp"
    }
  }
}

Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your Lambda Labs credentials.

Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/lambda-labs/

On first connect you'll provide your Lambda Cloud API key (Lambda Cloud dashboard → API keys). It is validated, stored per-user, and scoped to you — no keys in config files.
