WHAT IT DOES

What crow_add_source does on Crow

AI agents use crow_add_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_add_source is rated Medium

This tool creates new source records with metadata in the project management system. It is a Write operation because it creates/adds data reversibly without destructive or dangerous side effects. Severity is medium because misuse could pollute the project's source database with invalid, malicious, or irrelevant citations, but the impact is limited to data quality rather than data loss or system compromise.

From the tool's definition Tool description states it 'Add[s] a source' which is a data creation/modification operation. The mention of 'metadata' and 'automatic citation generation' indicates structured data is being created and stored.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs crow_add_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_add_source, this is the rule to start with:

crow_add_source Rate-limited

crow_add_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.
