List configured Notion data source aliases with metadata such as id, name, description, key_property, title_property, and status_property.
AI agents call notion_source_list to retrieve information from Notion DB MCP Helper without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a straightforward data retrieval operation—listing metadata about configured Notion sources. It has no side effects, does not modify data, execute code, delete resources, or involve financial transactions. The blast radius of misuse is minimal (information disclosure of metadata), making it a low-severity Read operation.
From the tool's definition Tool name 'notion_source_list' and description 'List configured Notion data source aliases with metadata' indicate a read-only operation that retrieves and returns configuration information without modification.
Attacks that exploit this kind of access
List configured Notion data source aliases with metadata such as id, name, description, key_property, title_property, and status_property. It is categorised as a Read tool in the Notion DB MCP Helper MCP Server, which means it retrieves data without modifying state.
Register the Notion DB MCP Helper MCP server in PolicyLayer and add a rule for notion_source_list: 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 DB MCP Helper. Nothing to install.
notion_source_list 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 notion_source_list 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 notion_source_list. 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.
notion_source_list is provided by the Notion DB MCP Helper MCP server (trisetiohidayat/notion-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
