Get the top properties for a specific event. Returns property names ranked by prevalence.
AI agents call event_properties to retrieve information from Mixpanel MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata about event properties without creating, modifying, deleting, or executing operations. It is purely informational and presents minimal risk even if misused by an agent, as it only exposes property name frequencies without enabling data exfiltration at scale or destructive actions.
From the tool's definition Tool description states 'Get the top properties for a specific event. Returns property names ranked by prevalence.' — a retrieval operation with no mutation or side effects. Sibling tools include query_* and list_* operations typical of analytics read access.
Attacks that exploit this kind of access
Get the top properties for a specific event. Returns property names ranked by prevalence. It is categorised as a Read tool in the Mixpanel MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Mixpanel MCP Server MCP server in PolicyLayer and add a rule for event_properties: 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 Mixpanel MCP Server. Nothing to install.
event_properties 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 event_properties 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 event_properties. 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.
event_properties is provided by the Mixpanel MCP Server MCP server (t-campbell18/mcp-mixpanel). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
