WHAT IT DOES

What oracle-set does on Xrpl mcp

AI agents use oracle-set 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 oracle-set is rated Medium

The tool modifies oracle data on the XRP Ledger, which is a reversible write operation. While it doesn't delete data (which would be Destructive) or move funds (Financial), it does alter state that other applications may depend on. Oracle data affects price feeds used by other contracts and applications, so misuse could cause significant downstream harm through corrupted price information.

From the tool's definition Set or update Oracle data on the XRP Ledger — the verb 'set or update' indicates modification of ledger state. This is a write operation that creates or modifies data on a blockchain.

RECOMMENDED RULE

The rule that runs oracle-set 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 oracle-set, this is the rule to start with:

oracle-set Rate-limited

oracle-set 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 Xrpl mcp, apply this rule, and every oracle-set call is checked against it from then on.

What risk level is oracle-set? +

Can I rate-limit oracle-set? +

Yes. Add a rate_limit block to the oracle-set 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 oracle-set completely? +
