Query a saved funnel by ID. Returns conversion rates and drop-off at each step.
AI agents call query_funnels 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 pre-computed funnel analysis data (conversion rates and drop-off metrics) from Mixpanel. It performs a read-only query operation with no side effects, no data modification, and no code execution. While the Mixpanel server can access sensitive analytics data, this particular tool is a straightforward data retrieval operation.
From the tool's definition Tool name 'query_funnels' and description 'Query a saved funnel by ID. Returns conversion rates and drop-off at each step' indicate retrieval of analytics data without modification or execution of external operations.
Attacks that exploit this kind of access
Query a saved funnel by ID. Returns conversion rates and drop-off at each step. 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 query_funnels: 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.
query_funnels 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 query_funnels 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 query_funnels. 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.
query_funnels 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.
