Read-only list of all indexed XRC events for one contract.
AI agents call get_xrc_contract_events 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 performs a read-only query to list historical events associated with a blockchain contract. It retrieves data without modifying, executing, or deleting anything. The 'read-only' designation and list/get pattern confirm it belongs to the Read category. Severity is low because querying historical event data on a public blockchain carries minimal risk of misuse by an AI agent.
From the tool's definition Tool name 'get_xrc_contract_events' and description 'Read-only list of all indexed XRC events for one contract' explicitly indicate a retrieval operation with no side effects.

Read-only list of all indexed XRC events for one contract. 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_events: 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_events 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_events 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_events. 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_events 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.
