update_conference · Confd MCP: Risk & Policy

WHAT IT DOES

What update_conference does on Confd

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

WHY IT NEEDS A POLICY

Why update_conference needs a policy

The tool creates or modifies data reversibly (the definition of Write). It updates conference records without permanently deleting them, so it is not Destructive. It does not execute arbitrary code or commands, so it is not Execute. The moderate severity reflects that a misused update could corrupt conference data, but the effect is reversible (data can be corrected or restored), preventing a higher rating.

From the tool's definition Tool name is 'update_conference' and description states 'Update an existing conference by ID. Only include fields you want to change.' — this modifies existing data.

update_conference Rate-limited
