Compare multiple protocols side-by-side: TVL, deposits, borrows, revenue, users, pools. Sorted by TVL. Tolerates individual endpoint failures.
AI agents call compare_protocols 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 performs read-only aggregation and comparison of blockchain lending protocol data. It queries structured information across multiple protocols and returns sorted results—a pure retrieval operation with no side effects. No data is created, modified, deleted, or financial transactions are triggered.
From the tool's definition Tool description states it 'Compare[s] multiple protocols side-by-side' retrieving metrics like 'TVL, deposits, borrows, revenue, users, pools' and 'Sorted by TVL'.
Attacks that exploit this kind of access
Compare multiple protocols side-by-side: TVL, deposits, borrows, revenue, users, pools. Sorted by TVL. Tolerates individual endpoint failures. 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 compare_protocols: 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.
compare_protocols 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 compare_protocols 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 compare_protocols. 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.
compare_protocols 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.
