Get the most common events over the last day. Returns event names ranked by volume.
AI agents call top_events 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.
The tool retrieves and ranks event data for analytics purposes. It performs a read-only query against historical analytics data with no ability to modify, delete, or execute operations. The blast radius of misuse is minimal—an agent could only retrieve aggregate event statistics that are likely already accessible to users with Mixpanel access. This is a standard analytics query operation.
From the tool's definition Tool description states it 'Get the most common events over the last day. Returns event names ranked by volume.' This is a retrieval operation with no modification or side effects.
Attacks that exploit this kind of access
Get the most common events over the last day. Returns event names ranked by volume. 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 top_events: 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.
top_events 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 top_events 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 top_events. 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.
top_events 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.
