Bargainer MCP Server

Instructions

Implementation Reference

• src/server.ts:400-414 (handler)

  The primary handler function for the 'get_available_sources' MCP tool. It fetches available providers from the aggregator and returns a standardized JSON response.

  private async handleGetAvailableSources() {
    const sources = this.aggregator.getProviders();
  
    return {
      content: [
        {
          type: 'text',
          text: JSON.stringify({
            success: true,
            sources: sources
          }, null, 2),
        },
      ],
    };
  }

• src/server.ts:275-282 (registration)

  Tool registration in the listTools response, defining name, description, and input schema (empty object since no parameters required).

  {
    name: 'get_available_sources',
    description: 'Get list of available deal sources/providers',
    inputSchema: {
      type: 'object',
      properties: {},
    },
  },

• src/server.ts:278-281 (schema)

  Input schema definition for the tool (empty properties as it takes no arguments).

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

• src/services/aggregator.ts:15-17 (helper)

  Supporting helper method that returns the names of all registered deal providers, called by the tool handler.

  getProviders(): string[] {
    return Array.from(this.providers.keys());
  }
