create_workflow · Rockfish MCP Server MCP: Risk & Policy

WHAT IT DOES

What create_workflow does on Rockfish MCP Server

AI agents invoke create_workflow to trigger actions in Rockfish MCP Server. 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 create_workflow needs a policy

The tool spans both Write (create) and Execute (run) categories. Since it actively triggers execution of a workflow on an ML platform, which can have broad side effects (data processing, model training, resource consumption), Execute is the most severe applicable category.

From the tool's definition 'Create and run a new workflow' — the tool not only creates but also immediately runs/executes the workflow, triggering external ML operations whose effects depend on arguments

Verdict

create_workflow Rate-limited

create_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.

FAQ

Questions about create_workflow

What does the create_workflow tool do? +

Create and run a new workflow. It is categorised as a Execute tool in the Rockfish MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on create_workflow? +

Register the Rockfish MCP Server MCP server in PolicyLayer and add a rule for create_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 Rockfish MCP Server. Nothing to install.

What risk level is create_workflow? +

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

Can I rate-limit create_workflow? +

Yes. Add a rate_limit block to the create_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.

How do I block create_workflow completely? +

Set action: deny in the PolicyLayer policy for create_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 create_workflow? +

create_workflow is provided by the Rockfish MCP Server MCP server (wolfdancer/rockfish-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
