mlab.sh MCP server

Public metadata and connection guide for the remote MCP server at https://mlab.sh/mcp, a threat intelligence server for SOC and DFIR work.

This repo is the registry listing and the documentation. It is not the server source: the server runs inside the mlab.sh backend and is closed source.

Connect

Endpoint: https://mlab.sh/mcp (Streamable HTTP via POST, SSE via GET).

Claude.ai

Settings > Connectors > Add custom connector, then paste the URL. OAuth runs in the browser, no token to copy.

https://mlab.sh/mcp

Claude Desktop

claude_desktop_config.json:

{
  "mcpServers": {
    "mlab": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://mlab.sh/mcp",
        "--header",
        "Authorization: Bearer mcp_xxx"
      ]
    }
  }
}

Drop the --header pair to use OAuth instead of a static token.

Cursor

~/.cursor/mcp.json:

{
  "mcpServers": {
    "mlab": {
      "url": "https://mlab.sh/mcp",
      "headers": {
        "Authorization": "Bearer mcp_xxx"
      }
    }
  }
}

VS Code

.vscode/mcp.json:

{
  "servers": {
    "mlab": {
      "type": "http",
      "url": "https://mlab.sh/mcp",
      "headers": {
        "Authorization": "Bearer mcp_xxx"
      }
    }
  }
}

curl

curl -sS -X POST https://mlab.sh/mcp \
  -H "Authorization: Bearer mcp_xxx" \
  -H "Content-Type: application/json" \
  -H "Accept: application/json, text/event-stream" \
  -d '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2025-06-18","capabilities":{},"clientInfo":{"name":"curl","version":"1.0.0"}}}'

Ready to paste versions of these four configs live in examples/.

Officially supported clients are Claude.ai and Claude Desktop. Other MCP clients (Cursor, VS Code, Windsurf and friends) work but are best effort.
