WHAT IT DOES

What notion_action does on CoWork OS

AI agents use notion_action to create or update resources in CoWork OS, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your CoWork OS environment.

RISK

Why notion_action is rated Medium

The tool performs read operations (search, read) which would normally be 'Read' category, but the explicit mention of 'update' capability elevates this to 'Write' since it can create or modify data reversibly.

From the tool's definition Tool description states it can 'search, read, and update pages/data sources' in Notion. The 'update' capability indicates modification of data.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs notion_action safely

PolicyLayer is an MCP gateway: it sits between your AI agents and CoWork OS, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For notion_action, this is the rule to start with:

notion_action Rate-limited

notion_action stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
