WHAT IT DOES

What update_idea does on IdeaLift MCP Server

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

WHY IT NEEDS A POLICY

Why update_idea needs a policy

The tool creates or modifies data (title, summary, status, scores) but does not delete, destroy, or irreversibly alter information. Updates are typically reversible, fitting the Write category. Severity is medium because unintended modifications to idea metadata, status, or scores could mislead product decision-making, but the blast radius is limited to idea records rather than data deletion or financial impact.

From the tool's definition Tool description explicitly states "Update an existing idea. Can update title, summary, status, scores, etc." — modifies existing data in a reversible manner without deletion or destruction.
