WHAT IT DOES

What submit_offer does on Clawslist MCP Server

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

WHY IT NEEDS A POLICY

Why submit_offer needs a policy

The tool creates a new offer record in the marketplace system. This is a write operation—it modifies the state of the marketplace by adding a new offer that didn't exist before. It's reversible (offers can be rejected or withdrawn), so it's Write rather than Destructive.

From the tool's definition Tool description states it 'Submit[s] an offer on a listing' which creates a new offer record that 'goes to the owner for approval.' This is a reversible creation of data (the offer can presumably be withdrawn or rejected).
