WHAT IT DOES

What crow_verify_source does on Crow

AI agents use crow_verify_source to create or update resources in Crow, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Crow environment.

RISK

Why crow_verify_source is rated Medium

This tool modifies the verification status of a source, which is a reversible state change (can be toggled between verified/unverified). It creates or updates metadata about a source without irreversibly deleting data, placing it in the Write category. Misuse could affect trust signals in the project management system, leading to medium severity.

RECOMMENDED RULE

The rule that runs crow_verify_source safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Crow, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For crow_verify_source, this is the rule to start with:

crow_verify_source Rate-limited

crow_verify_source stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
