Current supply and borrow APRs across all markets in a protocol. Optionally filter by side (LENDER/BORROWER) or rate type (VARIABLE/STABLE/FIXED).
AI agents call get_interest_rates to retrieve information from Graph Lending without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns interest rate data from lending protocols without creating, modifying, deleting, or executing any operations. It is purely informational retrieval. While interest rate data may inform financial decisions, the tool itself does not move money, execute transactions, or trigger external operations—it only reads and returns structured data.
From the tool's definition Tool retrieves current supply and borrow APRs across markets with optional filtering by side or rate type. Uses verbs 'get' and 'retrieves', with no modification, deletion, execution, or financial transaction capability.
Attacks that exploit this kind of access
Current supply and borrow APRs across all markets in a protocol. Optionally filter by side (LENDER/BORROWER) or rate type (VARIABLE/STABLE/FIXED). It is categorised as a Read tool in the Graph Lending MCP Server, which means it retrieves data without modifying state.
Register the Graph Lending MCP server in PolicyLayer and add a rule for get_interest_rates: 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 Graph Lending. Nothing to install.
get_interest_rates 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_interest_rates 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_interest_rates. 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_interest_rates is provided by the Graph Lending MCP server (paulieb14/graph-lending-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
