report_vuln · Ruflo MCP: Risk & Policy

WHAT IT DOES

What report_vuln does on Ruflo

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

WHY IT NEEDS A POLICY

Why report_vuln needs a policy

The tool generates (creates) a vulnerability report, which is a Write operation producing a new document or record. It does not appear to execute code, delete data, or move money. Severity is medium because in an agentic multi-agent harness, a fabricated or misleading vulnerability report could trigger harmful downstream remediation actions.

Verdict

report_vuln Rate-limited

report_vuln 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.
