Implementation Reference

• src/index.ts:86-100 (handler)

  The main request handler for all MCP tool calls. When 'rr_get_lost_sales' is invoked, this handler extracts the tool name and arguments, then calls the callApi function to forward the request to the ReplenishRadar REST API.

  server.setRequestHandler(CallToolRequestSchema, async (request) => {
    const { name, arguments: args } = request.params;
    try {
      const result = await callApi(name, (args as Record<string, unknown>) || {});
      return {
        content: [{ type: 'text', text: JSON.stringify(result, null, 2) }],
      };
    } catch (error) {
      const message = error instanceof Error ? error.message : String(error);
      return {
        content: [{ type: 'text', text: `Error: ${message}` }],
        isError: true,
      };
    }
  });

• src/index.ts:43-43 (schema)

  Schema definition for 'rr_get_lost_sales' tool: accepts a 'days' parameter (number, default 30) to estimate lost sales from stockouts over that time period.

  { name: 'rr_get_lost_sales', description: 'Estimate lost sales from stockouts', inputSchema: { type: 'object' as const, properties: { days: { type: 'number', default: 30 } } } },

• src/index.ts:43-43 (registration)

  Registration of 'rr_get_lost_sales' tool in the TOOLS array with name, description ('Estimate lost sales from stockouts'), and inputSchema.

  { name: 'rr_get_lost_sales', description: 'Estimate lost sales from stockouts', inputSchema: { type: 'object' as const, properties: { days: { type: 'number', default: 30 } } } },

• src/index.ts:57-74 (helper)

  The callApi function that implements the actual tool execution logic. It makes a POST request to https://api.replenishradar.com/api/mcp/call with the tool name ('rr_get_lost_sales') and input parameters, returning the API response.

  async function callApi(toolName: string, input: Record<string, unknown>): Promise<unknown> {
    const resp = await fetch(`${BASE_URL}/api/mcp/call`, {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json',
        'Authorization': `Bearer ${API_KEY}`,
      },
      body: JSON.stringify({ tool: toolName, input }),
    });
  
    if (!resp.ok) {
      const errorBody = await resp.text();
      throw new Error(`API error ${resp.status}: ${errorBody}`);
    }
  
    const data = await resp.json();
    return data.result;
  }
