README
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-postandcontent-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
anytypes — 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
- In your Ghost Admin dashboard, go to Settings → Integrations
- Click Add custom integration, give it a name (e.g. "MCP")
- 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.
