## What it does

NextBlock CMS gives an agent access to content management on your self-hosted site. It can work with pages, posts, blocks, media, and site settings, so you can request content changes from your coding assistant instead of making each edit in the CMS yourself.

The MCP endpoint uses your site’s address and the `/api/mcp` path. Add that endpoint in Claude Code with the setup command below, substituting your site host. A deployed NextBlock site is required; without one, there is no endpoint to connect to.
