Deep-dive on a single market by its on-chain contract address. Returns balances, cumulative stats, position counts, risk parameters, rates, and rewards. Get market IDs from get_markets first.
AI agents call get_market 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 on-chain lending protocol data indexed by The Graph and returns structured information about a specific market. It performs read-only operations against a subgraph without creating, modifying, deleting, or executing state-changing operations. The low severity reflects that misuse retrieves publicly available blockchain data with no side effects or blast radius.
From the tool's definition Tool description uses retrieval language: 'Returns balances, cumulative stats, position counts, risk parameters, rates, and rewards.' The prefix 'get_' and verb 'Returns' indicate data retrieval with no modification.
Attacks that exploit this kind of access
Deep-dive on a single market by its on-chain contract address. Returns balances, cumulative stats, position counts, risk parameters, rates, and rewards. Get market IDs from get_markets first. 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_market: 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_market 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_market 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_market. 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_market 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.
