Notion MCP Integration

2 min read Updated May 19, 2026
Pages, databases, blocks, and workspace content from Notion, with cross-database query support and full-text search.

Notion holds the documentation, OKRs, project plans, and ad-hoc knowledge for many teams. Connecting Notion to clariBI puts that content one question away.

Why connect Notion

Notion search is fine when you know the page name. Cross-database queries and unstructured "what do we know about X?" questions usually require human navigation.

With Notion connected, you can ask "Summarize the engineering OKRs for this quarter", "Find every meeting note that mentions pricing", or "Show me page activity in the design space last week" and get answers grounded in your workspace content.

How the connection works

clariBI talks to Notion through its hosted MCP server at https://mcp.notion.com/sse. Authentication uses an OAuth flow that clariBI registers itself for (no developer console setup on your side). Tokens stay encrypted server-side and never leave clariBI in clear form.

    participant V as Notion
    U->>C: Click Authorize with Notion
    C->>V: Open OAuth authorization
    V-->>U: Grant read access?
    U->>V: Approve
    V-->>C: Authorization code
    C->>V: Exchange code for tokens
    V-->>C: Access + refresh tokens
    C->>C: Encrypt and store credentials
    C-->>U: Connection ready

Available tools

clariBI exposes the read-only Notion tools that the vendor's MCP server publishes at connection time. Write operations (create, update, delete, send, refund) are filtered out by a name-pattern blocklist before any tool reaches the analysis engine, so connecting Notion cannot modify data on the vendor side.

The exact tool inventory depends on the Notion features your account has access to. After connecting, try a few natural-language questions to see what Notion data clariBI can pull.

Data flow during analysis

When you ask a question that maps to Notion, the AI engine routes to the right tool, reads the result, and pairs the answer with a chart you can pin to a dashboard.

Setting up the connection

  1. Open Data Sources in the clariBI sidebar.
  2. Click Add data source.
  3. Open the MCP Servers tab.
  4. Click the Notion card.
  5. Click Authorize with Notion.
  6. Sign in to Notion in the popup window and grant the requested read scopes.
  7. Back in clariBI, give your data source a name.
  8. Click Finish.

Permissions and data access

clariBI requests read access to pages, databases, blocks, and users in the workspaces you select during authorization. No pages, blocks, or database rows can be created or modified. Disconnect from Notion settings or from clariBI Settings.

Troubleshooting
