Use this to estimate XDaLa/XRC-137 rule gas. Returns validation gas, branch gas, grant fees and worst-case totals from xgr_estimateRuleGas.
AI agents call estimate_xdala_rule_gas 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 and returns gas estimation data for XDaLa/XRC-137 rules without modifying any blockchain state, executing transactions, or triggering external operations. It is a pure informational query that helps users understand costs before taking action, making it a Read operation with low severity risk.
From the tool's definition Tool is described as using xgr_estimateRuleGas to return estimated gas values—validation gas, branch gas, grant fees and worst-case totals.
Attacks that exploit this kind of access
Use this to estimate XDaLa/XRC-137 rule gas. Returns validation gas, branch gas, grant fees and worst-case totals from xgr_estimateRuleGas. 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 estimate_xdala_rule_gas: 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.
estimate_xdala_rule_gas 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 estimate_xdala_rule_gas 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 estimate_xdala_rule_gas. 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.
estimate_xdala_rule_gas 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.
