Ferrule

Ferrule connects AI assistants to your Notion workspace through the Model Context Protocol (MCP), an open standard for AI tool integration.

Your AI assistant can search pages and databases, read page content and properties, query databases with filters and sorting, browse block content, list users, and read comments. It can also create and update pages, create databases, append content blocks, and add comments.

20 tools are available covering search, pages, databases, blocks, users, and comments. All operations run through a secure gateway with encrypted token storage (AES-256-GCM), per-client rate limiting, and multi-tenant organization isolation.

Ferrule acts as a pass-through — your Notion data is returned to the requesting AI assistant and is not stored or cached by Ferrule.

1. Sign up for a Ferrule account at app.ferrule.io and create an organization.
2. Go to the Integrations page in your Ferrule dashboard.
3. Click Connect on the Notion integration and authorize access to your workspace.
4. Go to the API Keys page and create a new API key.
5. Copy the MCP endpoint URL and API key shown on the API Keys page.
6. In your AI assistant's MCP configuration, add a new server with the Ferrule endpoint URL and your API key as a Bearer token.
7. Your AI assistant can now discover and use Notion tools. Try asking it to search your workspace or query a database.
