Process-Tool · Android MCP: Risk & Policy

WHAT IT DOES

What Process-Tool does on Android

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

WHY IT NEEDS A POLICY

Why Process-Tool needs a policy

An AI agent can call Process-Tool faster than any human can review — one bad instruction and it creates or modifies resources in Android by the hundred, each call as confident as the last.

Verdict

Process-Tool Rate-limited

Process-Tool 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.
