Run a funnel over a time window and return per-step visitor count, conversion from previous step, conversion from start, and average time to convert between steps. Returns truncated flags if the scan cap was hit.

AI agents invoke compute_funnel to trigger processes or run actions in Convalytics. Execute operations can have side effects beyond the immediate call -- triggering builds, sending notifications, or starting workflows. Rate limits and argument validation are essential to prevent runaway execution.
compute_funnel can trigger processes with real-world consequences. An uncontrolled agent might start dozens of builds, send mass notifications, or kick off expensive compute jobs. PolicyLayer enforces rate limits and validates arguments to keep execution within safe bounds.
Execute tools trigger processes. Rate-limit and validate arguments to prevent unintended side effects.

These attack patterns abuse exactly the kind of access compute_funnel gives an agent. Each links to the full case and the policy that stops it:
Other execute tools across the catalogue. The same approach applies to each: rate-limit and validate the arguments.
Run a funnel over a time window and return per-step visitor count, conversion from previous step, conversion from start, and average time to convert between steps. Returns truncated flags if the scan cap was hit.. It is categorised as a Execute tool in the Convalytics MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Convalytics MCP server in PolicyLayer and add a rule for compute_funnel: 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 Convalytics. Nothing to install.
compute_funnel is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the compute_funnel 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 compute_funnel. 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.
compute_funnel is provided by the Convalytics MCP server (https://api.convalytics.dev/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
