Connect JargonSync to Notion AI

JargonSync's MCP server is available in Notion through Custom MCP connections. On a personal Notion account you can add JargonSync yourself from Notion's connector settings. On Notion for organizations, an admin may need to enable or approve custom connectors first — if you don't see the option to add a connector, ask your Notion admin to make the JargonSync MCP server available for your workspace.

JargonSync works with any assistant that supports MCP connectors. Add it once and Notion AI can read your glossary and help keep your terms consistent across every page.

Before you start

  • •A JargonSync account with your glossary set up.
  • •Your JargonSync server URL (below).
  • •Connecting uses OAuth, so you sign in through JargonSync — you never paste an API key into Notion.
