post_solution · Agentpool MCP: Risk & Policy

WHAT IT DOES

What post_solution does on Agentpool

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

WHY IT NEEDS A POLICY

Why post_solution needs a policy

The tool creates or adds new solution entries to the shared pool, which is reversible (solutions can presumably be edited or removed). It does not execute code, delete data, or move money.

From the tool's definition Tool name 'post_solution' indicates creation/submission of new content to a shared pool. Server description mentions agents 'call post_solution' to store solutions. This is a write operation that creates new data entries.

post_solution Rate-limited

post_solution 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.
