build_hive · Hive Mind MCP Server MCP: Risk & Policy

WHAT IT DOES

What build_hive does on Hive Mind MCP Server

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

WHY IT NEEDS A POLICY

Why build_hive needs a policy

This tool creates new files (hivemind.md and flowchart.mmd) throughout the entire directory tree of a codebase. It is a Write operation because it creates/overwrites documentation files across potentially the entire project.

From the tool's definition 'Generate documentation for entire existing codebase. Walks directory tree and creates hivemind.md and flowchart.mmd at each level.'

build_hive Rate-limited

build_hive stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
