agloop_append_log · Agloop MCP: Risk & Policy

WHAT IT DOES

What agloop_append_log does on Agloop

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

WHY IT NEEDS A POLICY

Why agloop_append_log needs a policy

This tool writes new log entries to an execution log. It creates/modifies data (appending) but does not delete anything, execute code, or involve financial transactions. The blast radius is low since log entries are generally non-critical and the action is reversible in the sense that logs can be cleared or ignored, though the write itself is permanent.

agloop_append_log Rate-limited

agloop_append_log 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.
