Notion supports Member accounts through its official hosted MCP service. An administrator enables Notion under Settings → Sources, then each teammate connects their own Notion account under Integrations and authorizes a workspace. Search uses the connected member's current permissions.
The ordinary Notion OAuth connection used by workflow blocks and knowledge-base ingestion is separate. Live Search uses personal MCP OAuth for content search; the REST API's title-only search is not used as a fallback.
Search effectively
Use short, distinctive keywords such as launch rollback or a concise question such as Why did we postpone the migration?. Prefer one focused concept per query; shorten or rephrase a query that returns weak results. Read important matches before drawing conclusions.
Sim checks the connection's current tool access before searching. When available, it uses Notion AI search; otherwise it uses the advertised keyword-search route. Workspace plans and enabled MCP tools determine availability. Notion can return results from connected applications, but Sim's Notion provider returns only Notion pages and databases. Search Slack, Gmail, or Drive through their own providers for those sources.
The assistant can scope a query to a Notion page URL or ID when the server advertises page-scoped search. A server without that option reports the limitation. For date filters or sorting, Sim fetches up to 10 candidate pages and uses their explicit modification timestamps. They are not exhaustive date-range searches; date-only requests require search terms. Sim never substitutes the search time for a missing page date.
Coverage and reads
Search returns a bounded, ranked selection. Pagination is used only when both the advertised tool and response support it. If results are capped, external results are dropped, or Notion reports plan restrictions, Sim marks the coverage as partial and suggests refining the query.
Reads fetch the exact page or database through the same member connection. Large pages can omit subtrees; Sim preserves that limitation in the returned content. Open the original page when the result says its content is incomplete.
Search is limited to a fixed read-only allowlist: tool-access inspection, search, AI search, and fetch. It cannot create or edit Notion pages. The server URL is fixed to Notion's official endpoint, and every call is validated against the current advertised tool schema.
