WHAT IT DOES

What init_project_kb does on Hivemind MCP

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

WHY IT NEEDS A POLICY

Why init_project_kb needs a policy

This tool creates a new project-specific knowledge base resource in cloud storage. It is a creation/initialization action (Write), not destructive or financial. Misuse could result in unwanted knowledge bases being created or user IDs being generated, but the blast radius is moderate since no existing data is overwritten or deleted.

From the tool's definition Initialize a project-specific knowledge base with cloud storage. Returns user_id to store for future contributions.

What risk level is init_project_kb? +

init_project_kb is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit init_project_kb? +

Yes. Add a rate_limit block to the init_project_kb rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
