case "list_chains": const chainNames = await this.chainLookupService.listChainNames(); return { content: [ { type: "text", text: `Available chains:\n${chainNames.join("\n")}`, }, ], }; - src/index.ts:1038-1046 (registration)Tool registration in getAvailableTools(). Defines the 'list_chains' tool name, description, and empty input schema (no parameters required). Returned by ListToolsRequestSchema handler.
{ name: "list_chains", description: "List all available Arbitrum Orbit chains and their names. Use this to see what chains are available for querying.", inputSchema: { type: "object" as const, properties: {}, }, }, - src/index.ts:1042-1045 (schema)Input schema definition for 'list_chains' tool: empty object (no input parameters). Part of the tool registration object.
inputSchema: { type: "object" as const, properties: {}, }, - src/services/chain-lookup.ts:224-227 (helper)Helper method in ChainLookupService that retrieves and sorts the list of all known chain names. Called by the 'list_chains' handler.
async listChainNames(): Promise<string[]> { await this.ensureChainsData(); return this.chainsData.map(chain => chain.name).sort(); }
