Ghost MCP Server

This is a fork of MFYDev/ghost-mcp, now maintained and improved by @hithereiamaliff.

This Model Context Protocol (MCP) server provides a powerful and flexible way to manage your Ghost CMS instance using Large Language Model (LLM) interfaces. It offers comprehensive and secure access to your blog's administrative functions, allowing you to automate and streamline your content management workflows.

Features

• Enhanced Error Handling: Provides detailed status codes and response bodies.
• Modern Transport: Exclusively uses the Streamable HTTP transport, with all deprecated STDIO logic removed.
• Diagnostic Tools: Includes tools for troubleshooting API connectivity and configuration.
