Notion

Add the connection from eve's registry. This writes the initial definition under agent/connections/ and installs its authentication dependency when needed:

eve add connection/notion

Create agent/connections/notion.ts. The connection name is derived from the filename:

// agent/connections/notion.tsimport { connect } from "@vercel/connect/eve";import { defineMcpClientConnection } from "eve/connections";
export default defineMcpClientConnection({  url: "https://mcp.notion.com/mcp",  description: "Notion workspace: search and edit pages and databases.",  auth: connect("notion"),});

Connect owns the OAuth flow, and each end-user authorizes in their own browser before their first tool call.

Link your project, create the connector, and pull OIDC locally:

vercel linkvercel connect create notionvercel env pull

For JWT bearer, principalToSubject controls the asserted subject. The default maps app principals to { type: "app" } and user principals to { type: "user", id, issuer }.

The OpenAPI setup sends the required Notion-Version header; bump it as Notion ships new API versions.

See the Connections docs for principal types, headers, approval, and protocol-specific filters.
