create_contract · QuickContract MCP: Risk & Policy

WHAT IT DOES

What create_contract does on QuickContract MCP

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

WHY IT NEEDS A POLICY

Why create_contract needs a policy

This tool creates new contract documents, which is a reversible write operation (drafts can be modified or discarded before signing). It does not execute arbitrary code, delete data, or move funds directly—those are separate tools (signing, escrow release).

From the tool's definition Tool description states 'Create a new draft contract from a template. Fill in template fields via filledFields.' The verb 'create' and action of generating a new contract document are core Write operations.
