Use this to resolve payload fields for one currently WAITING wake-up target. It reads XRC-729.getOSTC(step -> XRC-137) and XRC-137.getRule() via eth_call for plain JSON rules. Encrypted rules are not decrypted server-side.
AI agents call resolve_wakeup_payload_schema 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.
The tool only performs read operations (eth_call) against blockchain contracts to resolve schema/payload fields. No data is written, modified, or deleted. eth_call is a non-mutating RPC method that queries contract state without creating transactions.
From the tool's definition 'It reads XRC-729.getOSTC(step -> XRC-137) and XRC-137.getRule() via eth_call for plain JSON rules' — pure on-chain read via eth_call with no state modification
Attacks that exploit this kind of access
Use this to resolve payload fields for one currently WAITING wake-up target. It reads XRC-729.getOSTC(step -> XRC-137) and XRC-137.getRule() via eth_call for plain JSON rules. Encrypted rules are not decrypted server-side. 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 resolve_wakeup_payload_schema: 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.
resolve_wakeup_payload_schema 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 resolve_wakeup_payload_schema 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 resolve_wakeup_payload_schema. 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.
resolve_wakeup_payload_schema 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.
