Activation required. AI access management must be enabled for your tenant before you can use it. To get started, contact the C1 support team for a walkthrough.
- Per-user OAuth (recommended). Each person authorizes with their own Notion account, so every tool call runs under that user’s Notion identity and permissions.
- Internal integration secret. A single token authenticates everyone, so all tool calls reach Notion as one shared identity.
How C1 connects to Notion
C1 hosts the Notion MCP server, so your users’ AI clients only ever see MCP tools — they never call Notion directly. When an AI client calls one of these tools, C1 makes the matching request to the Notion API using the credentials you configure here, then returns the result to the AI client. The credentials you set up below are what C1 uses to call Notion on your users’ behalf.Before you begin
- AI access management must be enabled for your tenant. See Enable AI access management.
- For per-user OAuth, you need permission to create a public integration. See Notion’s Create integrations with the Notion API documentation.
- For an internal integration secret, you need to be a Workspace Owner of the Notion workspace.
If you don’t see Notion in your MCP server catalog, contact the C1 support team to enable it for your tenant.
Option 1: Set up per-user OAuth
With per-user OAuth, you register one Notion public integration and each user authorizes individually. This keeps every action attributable to the user who took it, with only the access that user already has in Notion.Create a Notion public integration
Create a public integration in Notion that users will authorize through.In Notion’s developer portal, select New integration. See Notion’s Create integrations with the Notion API documentation.
On the Capabilities tab, enable only what C1 needs: Read content for read operations, plus Update content or Insert content if C1 should edit or create pages, and the comment and user-information capabilities you need.
Register the server with OAuth
With your public integration ready, register the server and provide its credentials to C1.Follow Register an MCP server and select Notion from the catalog.
When you configure authentication, choose per-user OAuth and enter your integration’s client ID and client secret.
Option 2: Use an internal integration secret
An internal integration secret authenticates every user as one shared Notion identity. Use this when per-user attribution in Notion isn’t required.Create an internal integration
Create an internal integration in Notion and connect it to the pages C1 should reach.In Notion’s developer portal, select New integration. See Notion’s Create integrations with the Notion API documentation.
Enter a recognizable name such as
C1, select the associated workspace, and set Type to Internal, then select Save.On the Capabilities tab, enable only what C1 needs: Read content for read operations, plus Update content or Insert content if C1 should edit or create pages, and the comment and user-information capabilities you need.
On the Configuration tab, under Internal Integration Secret, select Show and copy the token. Treat it as a high-value credential.
Register the server with a secret
With your internal integration secret ready, register the server and provide it to C1.Follow Register an MCP server and select Notion from the catalog.
When you configure authentication, choose Bearer token and paste your internal integration secret.
How Notion credentials are shared
How Notion sees your users’ activity depends on the method you chose:- Per-user OAuth. Each user authorizes with their own Notion account, so tool calls run under that user’s Notion identity and inherit only the access they already have. Notion attributes each action to the individual user.
- Internal integration secret. Every user’s tool calls use the one secret you provided, so Notion sees a single shared identity. C1 still attributes each call to the individual user in the AI tool usage audit log.
Discover and govern tools
After you register the server, C1 runs tool discovery against Notion. Discovered tools appear on the server’s Tools tab. Each tool starts as either Pending review or automatically Approved, depending on the option chosen when the server was set up or your tenant’s default tool settings in Settings > AI Connections. See Require tool approval and Default tool classification. Before anyone can call a Notion tool, it must be approved, added to a toolset, and bound to an access profile. Continue to Govern tools and toolsets to set this up.Tool discovery runs even if your credentials are incorrect, so seeing discovered tools doesn’t confirm that authentication is working. You confirm your Notion credentials when an approved user successfully calls a Notion tool from their AI client.
Manage your Notion credentials
- Rotate the OAuth client secret on your public integration’s Configuration tab in Notion, then update the secret on the server’s authentication settings in C1.
- Rotate the internal integration secret by regenerating it on the integration’s Configuration tab in Notion and updating it in C1.
- Adjust access by editing the integration’s capabilities, and for an internal integration, the set of pages it’s connected to.
