WHAT IT DOES

What delegate-set does on Xrpl mcp

AI agents use delegate-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 delegate-set is rated Medium

This tool creates or modifies access control settings on the XRP Ledger by delegating transaction permissions. While reversible (permissions can be revoked), the action has significant security implications as it grants another account the ability to submit transactions on behalf of the delegating account.

From the tool's definition "Delegate transaction permissions to another account on the XRP Ledger. Allows an account to authorize another account to submit specific transaction types on their behalf." This tool modifies account authorization state by delegating permissions to another…

RECOMMENDED RULE

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

delegate-set Rate-limited

delegate-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 delegate-set call is checked against it from then on.

FAQ

Questions about delegate-set

What does the delegate-set tool do? +

Delegate transaction permissions to another account on the XRP Ledger. Allows an account to authorize another account to submit specific transaction types on their behalf. Note: AccountSet, SetRegularKey, SignerListSet, DelegateSet, and AccountDelete cannot be delegated for security reasons. It is categorised as a Write tool in the Xrpl mcp MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on delegate-set? +

Register the Xrpl MCP server in PolicyLayer and add a rule for delegate-set: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Xrpl mcp. Nothing to install.

What risk level is delegate-set? +

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

Can I rate-limit delegate-set? +

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

Set action: deny in the PolicyLayer policy for delegate-set. 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 delegate-set? +

delegate-set is provided by the Xrpl MCP server (romthpt/mcp-xrpl). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
