AI agents use finalize_workflow to initiate financial transactions through ComfyUI Builder. Financial operations involve real money and are irreversible once processed. PolicyLayer blocks financial tools by default, requiring explicit human approval with transaction-level limits to prevent unauthorised spending.
finalize_workflow moves real money. Without a policy, an autonomous agent could initiate transactions that drain accounts or exceed budgets. PolicyLayer blocks financial tools by default, requiring human-in-the-loop approval with configurable spending limits per transaction and per time window.
Financial tools involve real money. Block by default and require explicit human approval before enabling.

These attack patterns abuse exactly the kind of access finalize_workflow gives an agent. Each links to the full case and the policy that stops it:
Other financial tools across the catalogue. The same approach applies to each: deny by default, or require human approval.
Get the workflow JSON for a dynamic workflow (same as get_workflow_json). Use with execute_workflow or save_workflow.. It is categorised as a Financial tool in the ComfyUI Builder MCP Server, which means it involves financial transactions. Block by default and require explicit approval.
Register the ComfyUI Builder MCP server in PolicyLayer and add a rule for finalize_workflow: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches ComfyUI Builder. Nothing to install.
finalize_workflow is a Financial tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the finalize_workflow rule in your PolicyLayer 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.
Set action: deny in the PolicyLayer policy for finalize_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.
finalize_workflow is provided by the ComfyUI Builder MCP server (mcp-comfy-ui-builder). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
