edit_assumption · Mipiti MCP Server MCP: Risk & Policy

WHAT IT DOES

What edit_assumption does on Mipiti MCP Server

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

WHY IT NEEDS A POLICY

Why edit_assumption needs a policy

The tool edits (modifies) assumptions, which are reversible changes to security documentation. While the description is empty, the name and context clearly indicate a Write operation on threat model data. The severity is medium because misuse could corrupt security threat models, but the changes are reversible and confined to security posture metadata rather than live systems or financial data.

From the tool's definition Tool name 'edit_assumption' and server context indicating the tool modifies threat model assumptions within the Mipiti security posture platform. Sibling tools like 'add_assumption' and 'add_evidence' confirm this server manages security posture data.
