List up to 400 XLS-70 Credential objects visible in an account owner directory, optionally filtered by whether the account is issuer or subject.
AI agents call credential_list to retrieve information from Xrpl Identity without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves credential metadata from the XRP Ledger without creating, modifying, deleting, or executing any transactions. It has optional filtering parameters (issuer/subject) but performs only read operations. The lack of side effects, irreversible actions, or financial implications places it clearly in the Read category with low severity.
From the tool's definition Tool name 'credential_list' and description 'List up to 400 XLS-70 Credential objects visible in an account owner directory' indicate retrieval/querying of existing data with no modification or deletion.
Attacks that exploit this kind of access
List up to 400 XLS-70 Credential objects visible in an account owner directory, optionally filtered by whether the account is issuer or subject. It is categorised as a Read tool in the Xrpl Identity MCP Server, which means it retrieves data without modifying state.
Register the Xrpl Identity MCP server in PolicyLayer and add a rule for credential_list: 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 Identity. Nothing to install.
credential_list is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the credential_list 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.
Set action: deny in the PolicyLayer policy for credential_list. 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.
credential_list is provided by the Xrpl Identity MCP server (jarod-vyent/xrpl-identity-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
credential_list is one line of Xrpl Identity's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
