Connect from Claude Desktop / Code

For Claude Desktop, edit claude_desktop_config.json and add an HTTP MCP server entry:

{
  "mcpServers": {
    "mtg-commander": {
      "type": "http",
      "url": "https://mtg-mcp.doodlemed.org/mcp"
    }
  }
}

For a stdio transport (Claude Desktop legacy, MCP Inspector, scripted clients), download a static binary below and point the client at the absolute path of the binary instead.

Download static binary

Go binaries built from the upstream nathanmartins/mtg-mcp source — statically linked, ~7 MB each, run the original stdio MCP transport directly.
