Returns annotations for a GA4 property. Annotations are notes that mark specific dates or periods, typically used to record events like releases, campaigns, or traffic changes.
AI agents call ga4_property_annotations to retrieve information from GA4 MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only retrieves existing annotation records from a GA4 property. It performs a query operation with no side effects. There is no capability to create, modify, delete, or execute operations. The data retrieved (historical notes about releases/campaigns) poses minimal security risk if accessed by an agent, as it is metadata rather than sensitive user data in most contexts.
From the tool's definition Tool description states it 'Returns annotations' which is a retrieval operation. Annotations are read-only reference data (notes marking dates/events). No modification, deletion, or execution capability described.
Attacks that exploit this kind of access
Returns annotations for a GA4 property. Annotations are notes that mark specific dates or periods, typically used to record events like releases, campaigns, or traffic changes. It is categorised as a Read tool in the GA4 MCP Server MCP Server, which means it retrieves data without modifying state.
Register the GA4 MCP Server MCP server in PolicyLayer and add a rule for ga4_property_annotations: 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 GA4 MCP Server. Nothing to install.
ga4_property_annotations 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 ga4_property_annotations 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 ga4_property_annotations. 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.
ga4_property_annotations is provided by the GA4 MCP Server MCP server (wonyoungseong/ga4-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
