Get the average of a numeric event property over time. Useful for tracking averages like order value.
AI agents call segmentation_average 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 is a read-only analytics query that aggregates existing event property data to compute statistics. It performs no writes, deletions, code execution, or financial transactions. The blast radius of misuse is minimal; an agent querying averages over unexpected time periods or properties causes no data loss or external side effects, only potentially misleading analytical reports.
From the tool's definition Tool 'segmentation_average' retrieves and calculates 'the average of a numeric event property over time' — a query operation that reads analytics data without modifying, deleting, or executing external operations.
Attacks that exploit this kind of access
Get the average of a numeric event property over time. Useful for tracking averages like order value. 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 segmentation_average: 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.
segmentation_average 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 segmentation_average 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 segmentation_average. 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.
segmentation_average 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.
