What add_repo does on Booster MCP

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

WHY IT NEEDS A POLICY

Why add_repo needs a policy

This tool creates a new indexed entry for a repository, which is a reversible write operation. It does not execute code, delete data, or move money. The severity is medium because misconfiguration could cause the system to index unintended repositories or consume computational resources, but the operation is reversible.

From the tool's definition Tool name 'add_repo' and description 'Добавляет репозиторий для индексации и индексирует его' (Adds a repository for indexing and indexes it) indicates the tool creates or modifies indexed data in the system.
