Lists all Notion databases accessible to the integration. Returns each database\
AI agents call list_databases to retrieve information from Notion MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only query of available databases. It retrieves metadata about existing resources without creating, modifying, deleting, or executing any operations. The blast radius is minimal - an AI agent calling this tool can only discover what databases exist, with no ability to modify data or trigger external effects.
From the tool's definition 'Lists all Notion databases accessible to the integration' - this is a retrieval operation with no side effects. It queries and returns data about existing databases without modifying, deleting, or executing any operations.
Attacks that exploit this kind of access
Lists all Notion databases accessible to the integration. Returns each database\. It is categorised as a Read tool in the Notion MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Notion MCP Server MCP server in PolicyLayer and add a rule for list_databases: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Notion MCP Server. Nothing to install.
list_databases is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the list_databases rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for list_databases. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
list_databases is provided by the Notion MCP Server MCP server (kazy1014/notion-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
