WHAT IT DOES

What check-create does on Xrpl mcp

AI agents use check-create 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 check-create is rated Medium

This tool creates a Check object on the XRP Ledger, which is a reversible financial instrument (it can be cancelled before being cashed). It writes a new ledger object but does not immediately move funds, distinguishing it from a direct payment.

RECOMMENDED RULE

The rule that runs check-create 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 check-create, this is the rule to start with:

check-create Rate-limited

check-create 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.

What risk level is check-create? +

check-create is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit check-create? +

Yes. Add a rate_limit block to the check-create rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block check-create completely? +

Set action: deny in the PolicyLayer policy for check-create. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides check-create? +
