WHAT IT DOES

What unblock_agent does on MIDAS Protocol

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

`agentId`	string	Yes

Parameters from the server's own tool schema.

RISK

Why unblock_agent is rated Medium

This tool reverses a prior block action, modifying the access/trust state of an agent relationship. It is a reversible write operation (the agent can be re-blocked), but misuse could expose the user to interactions with malicious or unwanted agents, giving it medium severity.

RECOMMENDED RULE

The rule that runs unblock_agent safely

PolicyLayer is an MCP gateway: it sits between your AI agents and MIDAS Protocol, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For unblock_agent, this is the rule to start with:

unblock_agent Rate-limited

unblock_agent 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.
