gt_formula_cook · Claude Flow MCP: Risk & Policy

WHAT IT DOES

What gt_formula_cook does on Claude Flow

AI agents invoke gt_formula_cook to trigger actions in Claude Flow. 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 gt_formula_cook needs a policy

The tool 'cooks' (compiles/transforms) a formula using WebAssembly acceleration with variable substitution. This implies executing a computation or code-transformation pipeline, likely producing an artifact (a 'protomolecule'). WASM execution with variable substitution can have significant side effects depending on what the formula contains.

From the tool's definition 'Cook a formula into a protomolecule with variable substitution (WASM accelerated)' — involves executing a WASM-accelerated compilation/transformation process

Verdict

gt_formula_cook Rate-limited

gt_formula_cook 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 gt_formula_cook

What does the gt_formula_cook tool do? +

Cook a formula into a protomolecule with variable substitution (WASM accelerated). It is categorised as a Execute tool in the Claude Flow MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on gt_formula_cook? +

Register the Claude Flow MCP server in PolicyLayer and add a rule for gt_formula_cook: 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 Claude Flow. Nothing to install.

What risk level is gt_formula_cook? +

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

Can I rate-limit gt_formula_cook? +

Yes. Add a rate_limit block to the gt_formula_cook 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 gt_formula_cook completely? +

Set action: deny in the PolicyLayer policy for gt_formula_cook. 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 gt_formula_cook? +

gt_formula_cook is provided by the Claude Flow MCP server (claude-flow). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
