@sentry/junior-notion

@sentry/junior-notion adds read-only Notion search workflows for pages and data sources to Junior through Notion's hosted MCP server.

Install it alongside @sentry/junior:

pnpm add @sentry/junior @sentry/junior-notion

Then register the plugin package in withJunior(...):

import { withJunior } from "@sentry/junior/config";

export default withJunior({
  pluginPackages: ["@sentry/junior-notion"],
});

This package does not use NOTION_TOKEN or a shared workspace integration. Each user connects their own Notion account the first time Junior calls a Notion MCP tool. Junior sends the OAuth link privately and resumes the thread automatically after the user authorizes.

Junior intentionally keeps this package read-only by exposing only Notion's notion-search and notion-fetch MCP tools. The plugin does not expose create, update, move, or other write-capable Notion tools.

Search limitations

This package uses Notion MCP search and fetch rather than the older REST helper flow.

• Search is still title-biased, so prompts work best when users search for the actual page or data source title.
• Results can differ from the Notion UI even when the user can see a page in the app.
• Search across connected sources like Slack, Google Drive, and Jira requires a Notion AI plan. Without Notion AI, search is limited to the user's Notion workspace.
• Missing results are usually a permissions problem on the user's Notion account or a weak query phrase.

Auth model

• Notion MCP requires user-based OAuth and does not support bearer token authentication.
• This package is not suitable for fully headless or unattended automation.
• Users can disconnect from Junior App Home with Unlink, or by asking Junior to disconnect Notion.
