Implementation Reference

• src/index.ts:189-224 (handler)

  The main handler function for the 'list_all_models' tool. It aggregates models from all configured providers (OpenAI, Anthropic, Google) by calling their respective listModels methods, handles errors for each, and returns a JSON string of the results.

  case 'list_all_models': {
    const results: any = {};
    
    if (openaiProvider) {
      try {
        results.openai = await openaiProvider.listModels();
      } catch (error) {
        results.openai = { error: error instanceof Error ? error.message : 'Failed to fetch OpenAI models' };
      }
    }
    
    if (anthropicProvider) {
      try {
        results.anthropic = await anthropicProvider.listModels();
      } catch (error) {
        results.anthropic = { error: error instanceof Error ? error.message : 'Failed to fetch Anthropic models' };
      }
    }
    
    if (googleProvider) {
      try {
        results.google = await googleProvider.listModels();
      } catch (error) {
        results.google = { error: error instanceof Error ? error.message : 'Failed to fetch Google models' };
      }
    }
    
    return {
      content: [
        {
          type: 'text',
          text: JSON.stringify(results, null, 2),
        },
      ],
    };
  }

• src/index.ts:70-77 (registration)

  Registration of the 'list_all_models' tool in the ListToolsRequestSchema handler, including name, description, and empty input schema (no parameters required).

  {
    name: 'list_all_models',
    description: 'List all available models from all configured providers',
    inputSchema: {
      type: 'object',
      properties: {},
    },
  },

• src/index.ts:73-77 (schema)

  Input schema for the 'list_all_models' tool, which is an empty object (no input parameters). Note: this overlaps with registration.

    inputSchema: {
      type: 'object',
      properties: {},
    },
  },
