Explain Hedera error codes and provide debugging guidance. USE FOR: - Understanding cryptic Hedera error codes (e.g., INSUFFICIENT_PAYER_BALANCE) - Getting step-by-step solutions for common errors - Finding related errors and security recommendations EXAMPLES: -
AI agents call error_explain to retrieve information from HashPilot without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a lookup/query operation to retrieve explanatory information about error codes. It has no side effects on blockchain state, does not execute transactions, and does not modify any data. The severity is low because misuse would only expose informational content about errors, not enable unauthorized transactions or data modification.
From the tool's definition The tool 'error_explain' retrieves and explains error code information and debugging guidance. The description emphasizes understanding, explaining, and providing information about Hedera errors.

Explain Hedera error codes and provide debugging guidance. USE FOR: - Understanding cryptic Hedera error codes (e.g., INSUFFICIENT_PAYER_BALANCE) - Getting step-by-step solutions for common errors - Finding related errors and security recommendations EXAMPLES: -. It is categorised as a Read tool in the HashPilot MCP Server, which means it retrieves data without modifying state.
Register the HashPilot MCP server in PolicyLayer and add a rule for error_explain: 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 HashPilot. Nothing to install.
error_explain 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 error_explain 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 error_explain. 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.
error_explain is provided by the HashPilot MCP server (justmert/hashpilot). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
