What the model can do

ButterCMS: blog posts (title, status, dates, author, categories, tags, summary and body), pages of each page type and their fields, collection items, and the authors, categories and tags; can create, update and delete blog posts, create and update pages, and create, update and delete collection items, as drafts or published.

Acts, when you ask

These change something in ButterCMS. The model is told to use them only when you ask for exactly that, and each one is granted by name: per team on a shared connection, by the owner on a personal one.

• buttercms_update_postChange a ButterCMS blog post by slug; only the fields given change.
• buttercms_delete_postDelete a ButterCMS blog post by slug.
• buttercms_create_pageCreate a ButterCMS page of an existing page type.

Connect it

First connect ButterCMS on Dashboard → Connections, then add Memtro to your client once. The ButterCMS tools appear alongside the tools of everything else you have connected; nothing is configured per connector.

Who may use it

The key identifies the person, and the server offers that person the tools they may use everywhere else in Memtro. A shared ButterCMS connection is used by the teams an administrator granted it to, tool by tool, on the Permissions page; a personal connection is used by its owner alone, and its tools that act stay off until the owner allows them. See Teams and permissions and Connectors.

Questions

Is this an official ButterCMS MCP server?

No. It is Memtro's MCP server with Memtro's ButterCMS connector behind it: the connector reads ButterCMS through its API with the credentials you connect on Dashboard → Connections, and ButterCMS publishes nothing here. The same endpoint carries every other system you connect and Memtro's memory tools.

What does it cost?

Nothing on top of Memtro. One price per organisation by its number of users, from $50 a month for up to 10 users after a 7-day free trial, with every connector, the MCP server, jobs and memory included. You bring your own model keys.

Can it change anything in ButterCMS?

Only when you ask, and only what it has been granted: create a blog post, as a draft or published; change a blog post's content, categories, tags or status; delete a blog post (soft delete, its slug is freed); create a page of an existing page type, as a draft or published; change a page's fields or status; add an item to a collection, as a draft or published; change a collection item's fields or status; delete a collection item (soft delete). Every other tool reads, searches or lists. An administrator grants each acting tool by name per team, and a personal connection acts only after its owner allows it.

Which clients work?

Any MCP client that speaks Streamable HTTP: Claude Code, Cursor, Claude Desktop, OpenCode, Codex, Zed, Windsurf, Cline and the Anthropic and OpenAI SDKs. There is no local process to run; the server is remote and authenticated with your key.
