Kudos to @burnyd for the inspiriation and for writing this blog post: https://danielhertzberg.net/posts/mcp-servers/

Expanding on that, I've added a few more API calls to be able to ask Claude to get connectivity monitor data, and create tags for Studios and dashboards, but obviously any API call can be added very easy with the `@mcp.tool()` decorator.

Example usage

1\. Create a .env file like the following.

3\. In Claude's developer settings update the claude_desktop_config.json and tell it to run your script like below:

      "args": [
        "run",
        "--with",
        "fastmcp",
        "fastmcp",
        "run",
        "/home/ansible/mcp-cvp-fun/mcp_server_rest.py"
      ]
    }
  }
}
