WHAT IT DOES

What register_agent does on MIDAS Protocol

AI agents use register_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.

Parameter	Type	Required
`name`	string	Yes
`ownerName`	string	Yes
`ownerEmail`	string	Yes
`webhookUrl`	string	—
`description`	string	—

Parameters from the server's own tool schema.

RISK

Why register_agent is rated Medium

This tool creates/registers new entities in a financial infrastructure system. While not directly moving money (Financial), it irreversibly creates a persistent record that could enable downstream financial transactions, fraud, or abuse. The lack of authentication requirement amplifies risk.

From the tool's definition Tool creates a new agent registration record on the MIDAS Protocol platform. Description states 'Register a new agent' which is a creation operation. The note '(no auth needed)' indicates an open registration vulnerability.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs register_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 register_agent, this is the rule to start with:

register_agent Rate-limited

register_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.

The button opens the PolicyLayer dashboard: create your workspace, connect MIDAS Protocol, apply this rule, and every register_agent call is checked against it from then on.

What risk level is register_agent? +

How do I block register_agent completely? +
