Ghost MCP

A Model Context Protocol server that gives Claude, Gemini, and any other MCP-compatible AI full access to your Ghost CMS via the Ghost Admin API.

Documentation languages: English · Français · Español

Features

• 47 tools across 10 resource types — posts, members, users, tags, tiers, offers, newsletters, invites, roles, and webhooks

• 7 MCP resources — fetch any Ghost entity by URI (e.g. post://abc123)

• 2 built-in prompts — summarize-post and content-audit

• Typed error handling — Ghost API errors are caught and surfaced as clean messages, not raw stack traces

• Full tool descriptions — every tool includes a plain-English description and per-parameter hints so the LLM understands exactly what to pass

• Zero any types — proper TypeScript interfaces throughout

Quick start

1. Prerequisites

• Node.js >= 18

• A Ghost site with Admin API access (Ghost Pro or self-hosted)

2. Get your Ghost credentials

1. In your Ghost Admin dashboard, go to Settings → Integrations

2. Click Add custom integration, give it a name (e.g. "MCP")

3. Copy the Admin API Key — it looks like id:secret

3. Pick your AI client

No cloning or building required. Every integration below uses npx @antoinefamibelle/ghost-mcp to run the server on demand.

Client integrations

Claude Desktop

The recommended integration. MCP is a native feature of Claude Desktop.

Config file location:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

• Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "ghost": {
      "command": "npx",
      "args": ["-y", "@antoinefamibelle/ghost-mcp"],
      "env": {
        "GHOST_API_URL": "https://yourblog.com",
        "GHOST_ADMIN_API_KEY": "your_id:your_secret",
        "GHOST_API_VERSION": "v5.0"
      }
    }
  }
}

Restart Claude Desktop. A hammer icon will appear in the chat input indicating all 47 tools are available.

Claude Code (CLI)

Run this once in your terminal — Claude Code will persist the server across sessions:

claude mcp add ghost \
  --command npx \
  --args "-y,@antoinefamibelle/ghost-mcp" \
  -e GHOST_API_URL=https://yourblog.com \
  -e GHOST_ADMIN_API_KEY=your_id:your_secret

Or add it manually to .claude/mcp.json in your project using the same JSON shape as Claude Desktop above.

Gemini CLI

Google's Gemini CLI supports MCP servers natively.

Config file: ~/.gemini/settings.json

{
  "mcpServers": {
    "ghost": {
      "command": "npx",
      "args": ["-y", "@antoinefamibelle/ghost-mcp"],
      "env": {
        "GHOST_API_URL": "https://yourblog.com",
        "GHOST_ADMIN_API_KEY": "your_id:your_secret",
        "GHOST_API_VERSION": "v5.0"
      }
    }
  }
}

Start a session with gemini and the Ghost tools will be available automatically.

ChatGPT

ChatGPT does not support MCP. OpenAI uses a separate plugin/GPT Actions system based on OpenAPI specs. There is no direct integration path — you would need to wrap this server in an HTTP REST layer to use it with ChatGPT.

Other MCP-compatible clients

Any client that speaks the MCP stdio transport can run this server. The command is always:

npx -y @antoinefamibelle/ghost-mcp

with GHOST_API_URL and GHOST_ADMIN_API_KEY set in the environment.
