Configure your client

Claude Desktop currently spawns MCP servers over stdio, so we bridge through the mcp-remote shim. Edit ~/Library/Application Support/Claude/claude_desktop_config.json:
{
  "mcpServers": {
    "mapping-travel": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote@0.1.37",
        "https://mcp.mapping.travel/mcp",
        "--header",
        "X-API-Key: mt_mcp_live_..."
      ]
    }
  }
}
Restart Claude Desktop. The tools appear under the wrench icon.
If you see npm ERR! code EACCES in ~/Library/Logs/Claude/mcp-server-mapping-travel.log, your npm cache has root-owned files from a previous sudo install. Run sudo chown -R $(id -u):$(id -g) ~/.npm once and restart Claude Desktop.

Verify

Ask your agent: “What mapping tools do you have available?” — it should list around 18 tools. If not, see Troubleshooting.
