deal_create · Llama MCP: Risk & Policy

WHAT IT DOES

What deal_create does on Llama

AI agents use deal_create to create or update resources in Llama — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Llama environment.

WHY IT NEEDS A POLICY

Why deal_create needs a policy

This tool creates a new deal record, which is a reversible write operation. It modifies the platform's state by adding a new deal to the pipeline, but the action can be undone (deals can be deleted as evidenced by sibling tool 'brief_delete').

From the tool's definition Tool name 'deal_create' and description 'Create a new pipeline deal' indicate the tool creates new data in a deal management system.

Verdict

deal_create Rate-limited

deal_create stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
