Input Schema
TableJSON Schema
| Name | Required | Description | Default |
|---|---|---|---|
| rpcUrl | No | The RPC URL of the Arbitrum node (optional if default is set) | |
| chainName | No | Chain name (e.g., 'Xai', 'Arbitrum One') - will auto-resolve to RPC URL |
Implementation Reference
- src/index.ts:668-682 (handler)MCP tool handler for 'maintenance_trigger'. Resolves RPC URL, creates NitroNodeClient instance, invokes triggerMaintenance method, and formats result as MCP response.
case "maintenance_trigger": { const rpcUrl = await this.resolveRpcUrl( (args.rpcUrl as string) || (args.chainName as string) ); const nodeClient = new NitroNodeClient(rpcUrl); const result = await nodeClient.triggerMaintenance(); return { content: [ { type: "text", text: JSON.stringify(result, null, 2), }, ], }; } - src/index.ts:1484-1504 (registration)Tool registration definition returned by listTools handler, including name, description, and input schema.
