Ghost MCP Server & AI Connector
The Model Context Protocol is the open standard assistants use to reach outside tools. Ghost AI Agent acts as an MCP server for your Ghost site: the assistant asks it for a capability, it checks what you have authorised, and only then does it touch your site. This page covers the technical side for Ghost.
What the connector talks to on Ghost
Ghost's Admin API, at /ghost/api/admin. It is part of Ghost itself, so nothing is installed on your publication.
A custom integration key. The key is never sent: it is decoded and used to sign a fresh token that is valid for five minutes, so an intercepted request cannot be replayed later.
Worth knowing about Ghost
Ghost has no search by title in its Admin API, so finding a post to change is done by listing rather than by querying.
What the platform does not allow
Editing a post requires sending the timestamp it was last changed, so a post edited elsewhere in the meantime is refused rather than overwritten. Ghost replaces its redirect list as a whole file, so redirects are deliberately not managed.
Authentication and permissions
The assistant authorises through OAuth 2.1 with PKCE, and is granted scopes rather than an open door. Your Ghost credential is encrypted at rest, tied to the one website it belongs to, and never sent to the assistant. Every operation is recorded, and an operation outside what you granted is refused before it reaches your site.
Everything above describes what Ghost’s interface offers. None of it is marked verified yet, which in this product means exercised against a live installation with the date recorded.
Common questions
What is an MCP server, in plain terms?
A service an AI assistant can call to do real work. Rather than describing a change to you, the assistant asks the server to make it. Ghost AI Agent is that server for Ghost, and the boundary of what it will do is set by what you authorised.
Does the assistant see my Ghost password or token?
No. The credential is encrypted and bound to the single website it was given for, so a copy of it elsewhere is useless. The assistant asks for an action; it never receives the way in.
Is this an official Ghost product?
No. Ghost AI Agent is an independent product that uses Ghost’s own published interfaces. It is not affiliated with or endorsed by Ghost.
