XenMCP for AI agents and vibe coding

You build your MCP server with Claude Code, Cursor, Codex or another coding agent? Give it one link: it reads our rules, makes the server ready for XenMCP and adds the manifest.

Prompt for your agent

Prepare an existing server

Read https://xenmcp.com/agents.md and make this MCP server ready for XenMCP: follow every rule, add an xenmcp.json in the repository root and work through the checklist at the end.

Build a new server

Build me an MCP server for <system> that runs on XenMCP. Rules and manifest: https://xenmcp.com/agents.md – read-only tools, write tools only behind an environment variable.

What the agent then takes care of

stdio or Streamable HTTP with an official MCP SDK, no sessions
Configuration and secrets only via environment variables
Read-only file system, only /tmp writable, no local state
256 MB RAM, 0.5 CPU, fast start after sleep
Outbound traffic only to declared hosts (egress)
Correct annotations: readOnlyHint, destructiveHint
Plain descriptions without instructions to the AI
No secrets, arguments or results in logs

Status

Hosting your own servers is planned after the beta launch; the rules describe how it will work and may still change. A server that follows them runs cleanly on any other MCP host, too. Your own MCP server →
