request_access · Computer Use MCP Server MCP: Risk & Policy

WHAT IT DOES

What request_access does on Computer Use MCP Server

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

WHY IT NEEDS A POLICY

Why request_access needs a policy

An AI agent can call request_access faster than any human can review — one bad instruction and it creates or modifies resources in Computer Use MCP Server by the hundred, each call as confident as the last.

Verdict

request_access Rate-limited

request_access 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.
