Implementation Reference

• src/tools/obtener-configuracion.js:19-45 (handler)

  The handler function for 'obtener_configuracion_chamber' tool. Validates input params using schema, determines contract address based on network (mainnet/sepolia), assembles config with supported tokens, and returns structured response.

  export async function obtenerConfiguracionChamber(params) {
      // Validate parameters
      const validated = ObtenerConfiguracionChamberSchema.parse(params);
      try {
          const contractAddress = validated.network === 'mainnet'
              ? CHAMBER_ADDR_MAINNET
              : CHAMBER_ADDR_SEPOLIA;
          const config = {
              contract_address: contractAddress,
              network: validated.network,
              supported_tokens: SUPPORTED_TOKENS[validated.network]
          };
          return {
              success: true,
              config,
              token_info: {
                  ETH: 'Native Starknet token',
                  USDC: 'USD Coin stablecoin',
                  USDT: 'Tether stablecoin',
                  DAI: 'DAI stablecoin'
              }
          };
      }
      catch (error) {
          throw new Error(`Failed to get Chamber configuration: ${error.message}`);
      }
  }

• src/utils/validation.js:37-39 (schema)

  Zod schema for input validation of the tool. Defines optional 'network' parameter with enum ['mainnet', 'sepolia'] defaulting to 'mainnet'.

  export const ObtenerConfiguracionChamberSchema = z.object({
      network: NetworkSchema
  });

• src/index.ts:141-155 (registration)

  Tool registration in ListToolsRequestSchema handler. Provides the tool name, description, and input schema for MCP discovery.

  {
      name: 'obtener_configuracion_chamber',
      description: 'Get Chamber contract configuration including contract address, network, and supported tokens.',
      inputSchema: {
          type: 'object',
          properties: {
              network: {
                  type: 'string',
                  enum: ['mainnet', 'sepolia'],
                  description: 'Starknet network',
                  default: 'mainnet',
              },
          },
      },
  },

• src/index.ts:206-214 (registration)

  Dispatch logic in CallToolRequestSchema handler. Routes calls to this tool name to the handler function and formats response.

  case 'obtener_configuracion_chamber':
      return {
          content: [
              {
                  type: 'text',
                  text: JSON.stringify(await obtenerConfiguracionChamber(args || {}), null, 2),
              },
          ],
      };
