// WHEN AI AGENTS USE THIS TOOL

AI agents invoke run_workflow to trigger processes or run actions in Comfyui Mcp Server Node. Execute operations can have side effects beyond the immediate call -- triggering builds, sending notifications, or starting workflows. Rate limits and argument validation are essential to prevent runaway execution.

// WHY ENFORCE A POLICY ON RUN_WORKFLOW

run_workflow can trigger processes with real-world consequences. An uncontrolled agent might start dozens of builds, send mass notifications, or kick off expensive compute jobs. Intercept enforces rate limits and validates arguments to keep execution within safe bounds.

// RECOMMENDED POLICY

Execute tools trigger processes. Rate-limit and validate arguments to prevent unintended side effects.

// FAQ

What does the run_workflow tool do? +

Run a specific workflow with parameter overrides. It is categorised as a Execute tool in the Comfyui Mcp Server Node MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on run_workflow? +

Add a rule in your Intercept YAML policy under the tools section for run_workflow. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Comfyui Mcp Server Node MCP server.

What risk level is run_workflow? +

run_workflow is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit run_workflow? +

Yes. Add a rate_limit block to the run_workflow rule in your Intercept policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block run_workflow completely? +

Set action: deny in the Intercept policy for run_workflow. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides run_workflow? +

run_workflow is provided by the Comfyui Mcp Server Node MCP server (comfyui-mcp-server-node). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
