# Notion API Hosted Notion MCP sessions list one content-search tool

Markdown version of <https://harbyn.com/changes/notion/2026-10-07-one-search-tool-in-notion-mcp>.

Behavior change - Notion API. low severity. In effect.

Hosted Notion MCP sessions now list one content-search tool, notion-search (search for OpenAI clients), whose description follows the user's AI search access. notion-ai-search no longer appears in tools/list but stays callable by name, so cached tool lists keep working. Workspace-owned MCP connections keep their earlier tool list and descriptions.
