Implementation Reference

• src/index.ts:86-100 (handler)

  The CallToolRequestSchema handler in src/index.ts dispatches all tool calls, including 'rr_get_suggested_purchase_orders', to the backend via the callApi helper function.

  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:29-29 (registration)

  Registration and definition of the 'rr_get_suggested_purchase_orders' tool in the TOOLS array.

  { name: 'rr_get_suggested_purchase_orders', description: 'Get suggested purchase orders', inputSchema: { type: 'object' as const, properties: { status: { type: 'string' }, vendor_id: { type: 'string' }, store_id: { type: 'string' }, limit: { type: 'number' } } } },

• src/index.ts:57-74 (helper)

  The callApi function acts as the generic handler that executes the logic for the tool by sending a POST request to the remote API.

  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;
  }
