Read-only lookup of one indexed XRC contract by address.
AI agents call get_xrc_contract to retrieve information from XGR MCP Gateway without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves contract information from the blockchain indexed data. It performs a query operation with no ability to modify, delete, or execute code. The read-only constraint and lookup semantics place it squarely in the Read category. Severity is low because misuse would only expose publicly available blockchain data, not cause system damage or loss.
From the tool's definition Tool name is 'get_xrc_contract' and description explicitly states 'Read-only lookup of one indexed XRC contract by address.' The terms 'read-only' and 'lookup' indicate data retrieval without side effects.
Attacks that exploit this kind of access
Read-only lookup of one indexed XRC contract by address. It is categorised as a Read tool in the XGR MCP Gateway MCP Server, which means it retrieves data without modifying state.
Register the XGR MCP Gateway MCP server in PolicyLayer and add a rule for get_xrc_contract: 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 XGR MCP Gateway. Nothing to install.
get_xrc_contract 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_xrc_contract 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_xrc_contract. 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_xrc_contract is provided by the XGR MCP Gateway MCP server (xgr-network/xgr-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
