execute-workflow · Ruflo MCP: Risk & Policy

WHAT IT DOES

What execute-workflow does on Ruflo

AI agents invoke execute-workflow to trigger actions in Ruflo. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why execute-workflow needs a policy

This is an Execute category tool because it triggers workflow execution whose side effects are dependent on workflow parameters and cannot be fully predicted without knowing the workflow contents. The high severity reflects that a malicious agent could use this to execute arbitrary workflows within the swarm system, potentially affecting multiple agents, data processing, and external integrations.

From the tool's definition Tool name 'execute-workflow' combined with description 'Execute a workflow' indicates the tool runs automated workflows whose effects depend on the workflow definition and arguments provided.

Verdict

execute-workflow Rate-limited

execute-workflow stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
