## Why marchward_register_agent is rated Medium

This tool creates and modifies data (agent registration records and API key issuance) but does not delete, execute arbitrary code, or commit financial transactions. The 'high' severity reflects that issuing credentials and registering agents could be misused to create unauthorized agents or compromise governance if called maliciously, though the effects are reversible via agent deletion or key revocation.

From the tool's own definition: "Tool description states 'Register a new agent' and 'Returns the agent record and its Marchward API key', indicating creation of a new record and issuance of credentials."

## Use case

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

## Recommended policy (PolicyLayer)
