AI agents call rybbit_list_funnels to retrieve information from Rybbit without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or enumerates funnel configurations—a read-only query operation. It has no side effects, does not create, modify, or delete data, and does not execute external operations or move funds. The blast radius of misuse is minimal; an agent querying funnel data cannot cause harm beyond potentially exposing analytical metadata about funnel configurations.
From the tool's definition Tool name 'rybbit_list_funnels' and description 'List all saved funnels for a site with their step definitions' indicate a retrieval operation that queries and returns existing funnel data without modification.

rybbit_list_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 rybbit_list_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.
