Hermes MCP — AI skill for Claude Code

hermes-mcp

An MCP server that lets **Claude Desktop**, **Claude.ai (web + mobile)**, **OpenAI Codex desktop**, **Cursor**, and any other MCP client (via OAuth 2.1 or static bearer token) delegate tasks to a local **[Hermes Agent](https://github.com/hermes-agent/hermes-agent)** running on your own hardware. (See [Client compatibility](#client-compatibility) for the current matrix.)

Use Claude (or another supported MCP client) as your daily chat. When you ask for something Hermes is built for — scheduling cron jobs, browser automation, email, document creation, persistent skills, WhatsApp/Slack messaging — your client calls Hermes through this bridge.
