AI agents call get_strx_records to retrieve information from Justlend without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read-only operation that queries user data without side effects. Even though the description is minimal, the naming pattern and server context (portfolio management utilities) clearly indicate a retrieval function. Severity is low because reading user records on a public blockchain has limited blast radius.
From the tool's definition Tool name 'get_strx_records' and description 'Get a user' indicate data retrieval with no modification or execution. The context (JustLend DAO portfolio management) suggests this retrieves user STRX-related records or data from the blockchain.
Attacks that exploit this kind of access
Get a user. It is categorised as a Read tool in the Justlend MCP Server, which means it retrieves data without modifying state.
Register the Justlend MCP server in PolicyLayer and add a rule for get_strx_records: 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 Justlend. Nothing to install.
get_strx_records 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 get_strx_records 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 get_strx_records. 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.
get_strx_records is provided by the Justlend MCP server (justlend/mcp-server-justlend). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
