Description

Cal MCP M8ven Score

MCP server for Calagopus Panel. It lets AI assistants such as Claude, Cursor and VS Code manage your panel through its API, limited to the permissions of the API key they connect with.

Requirements

Calagopus Panel 1.2.0 or newer.

Install

  1. In the panel, open Admin → Extensions and install dev_caloptreyx_calmcp.c7s.zip.
  2. Restart the panel.

Connect

  1. Create an API key under Account → API Keys. Give it only the permissions the assistant needs.
  2. Open Account → MCP. It shows the endpoint and ready-made setup for Claude Code, Cursor, VS Code and Claude Desktop, plus a prompt your AI agent can use to set itself up.

Endpoint:

https://your-panel.com/api/client/extensions/dev.caloptreyx.calmcp/mcp

Send the key as Authorization: Bearer <api key>. For example, in Claude Code:

claude mcp add --transport http calagopus https://your-panel.com/api/client/extensions/dev.caloptreyx.calmcp/mcp --header "Authorization: Bearer <api key>"

Tools

Tool What it does
search_api Finds panel API endpoints by keywords
describe_api Shows an endpoint's parameters, request body and response
read_api Sends a GET request to any /api/client or /api/admin endpoint
write_api Sends a POST, PUT, PATCH or DELETE request to any /api/client or /api/admin endpoint
list_servers Lists the servers the account can access
get_server Shows a server's details and live resource usage
power_server Starts, stops, restarts or kills a server

read_file Reads a text file
write_file Creates or replaces a text file

The four API tools cover every client and admin endpoint, including those added by other extensions.

Security

  • Every call runs as the API key, so the panel's own permission checks, rate limits and activity log apply.
  • Only API keys are accepted. Browser sessions are refused.
