book_room · DiSH MCP Server MCP: Risk & Policy

WHAT IT DOES

What book_room does on DiSH MCP Server

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

WHY IT NEEDS A POLICY

Why book_room needs a policy

Based on the server context, book_room almost certainly creates a new room reservation. This is a Write operation (reversible via cancel_booking sibling tool). Severity is high because an AI agent could create numerous unauthorized bookings on behalf of users, potentially blocking meeting rooms or committing organizational resources. Confidence is reduced due to empty tool description.

From the tool's definition Tool name 'book_room' combined with server description stating it can 'create bookings' and 'manage reservations' on the DiSH room booking platform.
