# Check tool access with notion-get-tool-access By Steven Van · 2026-09-17 A new MCP tool reports which Notion tools and parameters a workspace's plan restricts, so agents can check before calling them. [Notion]() MCP has a new [notion-get-tool-access]() tool that reports which tools work on a connection's plan. Calling it with an empty object returns the full current\_tool\_access map, and an optional tool\_names array such as \["search", "ai\_search"\] narrows the result to just those tools. It's meant to be called before using a tool whose availability depends on the plan, such as choosing between notion-search and notion-ai-search, and the result can be reused across multiple tool checks rather than looked up one at a time. The call only reads connection metadata: it doesn't grant access or change the workspace. Entries in the map can now include restricted\_parameters, listing a parameter path such as filters.title\_only alongside the reason it's unavailable. A restriction can apply even when the entry's overall status is available, so a workspace can support filters.teamspace\_ids for a single teamspace while restricting it for multiple teamspaces. When ai\_search is exposed and available, the map leaves out search entirely, even if it's requested by name; otherwise it can list both an available search entry and an unavailable ai\_search entry. ![Notion]() Notion All-in-one workspace for notes, docs, projects, and wikis — with AI built in for writing, summarizing, and organizing.
