Connect Claude to Your CMS: A 5-Minute Guide to the Cosmic MCP Server
If you already run Claude every day, the next obvious question is whether it can touch your content. Not summarize it. Not draft copy in a chat window you then paste somewhere. Actually read your content model, query it, and write back to it. Cosmic answers that with an MCP server. This guide gets you connected in about five minutes, then covers the part most people skip: what Claude is allowed…
This article provides a concise guide on connecting Claude to your Cosmic CMS in just five minutes. It explains that Model Context Protocol (MCP) is a standard way for an AI client like Claude to discover and call tools within your content model. The Cosmic MCP server exposes 18 bucket-scoped tools, covering objects, object types, media, and AI generation.
The guide outlines a simple five-step setup process:
1. Obtain your Bucket keys: Bucket slug, read key, and write key from your Cosmic dashboard.
2. Add the server to your MCP client configuration using the hosted endpoint provided by Cosmic.
3. Verify the connection by asking Claude to list object types in your Bucket and check the number of objects in each.
4. Once reads are successful, attempt real tasks like finding drafts with missing SEO descriptions or creating new posts.
The article emphasizes the importance of understanding and properly utilizing read and write keys for security. Giving an MCP client only a read-only key restricts it to read-only actions, preventing any accidental or malicious writes. If you need to perform writes, use a write-enabled key with a staging Bucket separate from your production Bucket.
The guide also mentions alternative ways to interact with Cosmic CMS programmatically using the TypeScript SDK, which covers the same functionality as the MCP server. This allows for bulk mechanical edits or draft generation based on your real content model.
Overall, the article provides a straightforward and secure method for integrating Claude with your Cosmic CMS, enabling powerful content management and automation capabilities while maintaining strict control over read and write operations.
