Implementation Reference

• src/index.ts:86-100 (handler)

  Generic handler for all tools, including rr_get_alerts, which dispatches requests to the external REST API via callApi.

  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:30-30 (registration)

  Registration of the rr_get_alerts tool within the TOOLS array.

  { name: 'rr_get_alerts', description: 'Get active alerts', inputSchema: { type: 'object' as const, properties: { status: { type: 'string' }, alert_type: { type: 'string' }, severity: { type: 'string' }, sku: { type: 'string' }, store_id: { type: 'string' }, limit: { type: 'number' }, offset: { type: 'number' } } } },

• src/index.ts:57-74 (helper)

  Helper function that executes the actual API call for tools by sending the request to the backend.

  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;
  }
