memo_regenerate · Llama MCP: Risk & Policy

WHAT IT DOES

What memo_regenerate does on Llama

AI agents invoke memo_regenerate to trigger actions in Llama. 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 memo_regenerate needs a policy

This tool triggers an external operation (server-side regeneration) rather than simply reading or writing static data. While regeneration is typically reversible (not Destructive), it executes code/logic on the server whose exact outcome cannot be fully predicted without knowing the regeneration algorithm. It could modify existing memo content, though likely in a controlled manner.

From the tool's definition Tool name 'memo_regenerate' and description 'Trigger server-side regeneration of the deal memo' indicate execution of a server-side operation whose effects depend on the current state of the deal memo and regeneration logic.

Verdict

memo_regenerate Rate-limited

memo_regenerate 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 memo_regenerate

What does the memo_regenerate tool do? +

Trigger server-side regeneration of the deal memo. Synchronous:. It is categorised as a Execute tool in the Llama MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on memo_regenerate? +

Register the Llama MCP server in PolicyLayer and add a rule for memo_regenerate: 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 Llama. Nothing to install.

What risk level is memo_regenerate? +

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

Can I rate-limit memo_regenerate? +

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

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

memo_regenerate is provided by the Llama MCP server (llama-ventures/llama-cli). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
