Read-only authority lookup for one XRC-729 orchestration contract. Reads owner()/getOwner() and getExecutorList(), detects zero-address executor wildcard, and never signs, submits, executes, or creates a handoff.
AI agents call get_xrc729_authority 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 pure data retrieval from blockchain contracts with no side effects. The explicit statement that it 'never signs, submits, executes, or creates a handoff' confirms it has no capacity for state modification or execution. Reading contract ownership and executor lists poses minimal security risk as the data is already public on-chain.
From the tool's definition Tool description explicitly states 'Read-only authority lookup' and 'never signs, submits, executes, or creates a handoff'. It reads owner() and getExecutorList() without modifying state.
Attacks that exploit this kind of access
Read-only authority lookup for one XRC-729 orchestration contract. Reads owner()/getOwner() and getExecutorList(), detects zero-address executor wildcard, and never signs, submits, executes, or creates a handoff. 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_xrc729_authority: 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_xrc729_authority 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_xrc729_authority 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_xrc729_authority. 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_xrc729_authority 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.
