The Marble MCP server is now available, making it easier to connect AI agents and MCP clients directly to your Marble workspace.
With MCP, tools like Cursor, Claude Code, Codex, and other compatible clients can read and manage your Marble content using your existing API key.
What you can do
Read and search posts from your workspace, including drafts when your API key allows it.
Create and update posts with clean HTML content, metadata, authors, tags, categories, cover images, and publish dates.
Manage workspace resources like categories, tags, and authors without leaving your AI client.
Use safer tool hints so agents understand which tools read data and which tools can update or delete content.
Built on the Marble API
The MCP server uses the same Marble API you already use today. Public keys can read content, while private keys are required for write operations like creating, updating, or deleting resources.
We also added agent-facing guidance for post content, including supported HTML, image and video figure markup, YouTube embeds, and X/Twitter embed markers. This helps agents create content that behaves well in Marble and on your frontend.
Get started
You can connect using Streamable HTTP at https://mcp.marblecms.com/mcp, or follow the client-specific setup guide in the Marble MCP documentation.
