run_workflow · MCPify MCP: Risk & Policy

WHAT IT DOES

What run_workflow does on MCPify

AI agents invoke run_workflow to trigger actions in MCPify. 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 run_workflow needs a policy

The verb 'run' combined with 'workflow' strongly suggests code/process execution. Without a description to bound the scope or clarify reversibility, and given the sibling tools include operations like 'call_nested_mcp' and 'api_operation', this tool most likely executes external operations or triggers automated logic whose effects depend on workflow arguments.

From the tool's definition Tool name 'run_workflow' indicates execution of a workflow or sequence of operations. Description is empty, providing no constraints on what workflows can be executed or their scope.

Verdict

run_workflow Rate-limited

run_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.
