WHAT IT DOES

What set-regular-key does on Xrpl mcp

AI agents use set-regular-key to create or update resources in Xrpl mcp, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Xrpl mcp environment.

RISK

Why set-regular-key is rated Medium

set-regular-key modifies account configuration by changing signing keys, which is a reversible write operation. While it could enable unauthorized access if misused, the operation itself is Write (not Execute, as it doesn't trigger arbitrary code execution).

From the tool's definition Tool description states 'Assign, change, or remove a regular key pair for an account' — this modifies account security settings reversibly.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs set-regular-key safely

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

set-regular-key Rate-limited

set-regular-key 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.
