pull-image · Android MCP: Risk & Policy

WHAT IT DOES

What pull-image does on Android

AI agents use pull-image 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 pull-image needs a policy

An AI agent can call pull-image 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

pull-image Rate-limited

pull-image 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.

How do I enforce a policy on pull-image? +

Register the Android MCP server in PolicyLayer and add a rule for pull-image: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Android. Nothing to install.

What risk level is pull-image? +

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

Can I rate-limit pull-image? +

Yes. Add a rate_limit block to the pull-image 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.

How do I block pull-image completely? +
