    How to connect

    How to connect Petstore MCP Server to Claude

    The server address to paste into Claude settings:

    https://petstore.run.mcp.com.ai/mcp

    1. Open Claude (claude.ai or the desktop app).
    2. Go to Settings → Connectors.
    3. Click Add custom connector.
    4. Paste the server address copied below into Remote MCP server URL and click Add.
    5. In a chat, click + → Connectors and switch the new connector on.

    Custom connectors are available on Free, Pro, Max, Team and Enterprise plans (Free is limited to one). On Team and Enterprise an organization Owner adds the connector first under Organization settings → Connectors.

    4. Fill in the form: Name (anything), Description (one line about what the service does), MCP server URL (copy it below).
