What is Smart MCP Server Feature
The Smart MCP Server feature automatically provides APIs published through the Smart API Gateway feature as Model Context Protocol (MCP) servers. This enables AI agents and LLMs (Large Language Models) to directly call APIs through remote MCP Servers that work in conjunction with API publishing via Smart API Gateway. This allows existing APIs to be instantly provided in a format usable by AI agents, accelerating AI-driven application development.
Feature Overview
Automatic MCP Server Deployment
- Simultaneous deployment: When an API is published via Smart API Gateway, the MCP Server is automatically deployed simultaneously
- No additional configuration required: MCP Server configuration is unnecessary once Smart API Gateway feature setup is complete
- Schema updates: Changes to API definitions are automatically reflected in the MCP Server
Supported AI Services
Currently, the Smart MCP Server feature can be verified with the following AI services:
OpenAI Playground
- Support status: ✅ Verified working
- Usage method: Add as MCP Server from Tools
A paid OpenAI account is required
Tutorial
Overview
Duration: Approximately 15-20 minutes
Prerequisites: API must already be published via Smart API Gateway feature
Before starting this tutorial, you must have already published an API using the Smart API Gateway feature.
If you haven't completed the setup yet, please first complete the Smart API Gateway feature setup procedure.
📋 Smart MCP Server Feature Tutorial (Click to expand)
This tutorial explains the procedure for setting up APIs published via Smart API Gateway feature as MCP Servers that can be used by AI services.
Step 1: Confirm MCP Server Endpoint
- Log in to the SaaS Development Console
- Select Smart API Gateway from the left menu
- Confirm that the API is in a published state
- When you scroll down the screen, the following information will be displayed, so please note it down:
- MCP Server Endpoint: The endpoint for AI services to connect to
Step 2: Confirm API Key
- Log in to the SaaS Operation Console
- Select Users from the left menu
- Click the API Key Management button in the Actions column for a specific user
- Note down the API key displayed in the dialog (if not yet issued, please issue a new one)
Step 3: Prepare OpenAI Playground
Using OpenAI Playground requires a paid OpenAI account. It cannot be used with a free account.
Additionally, usage fees are incurred for each API call, so please manage your budget appropriately with proper settings.
OpenAI Account Preparation
This step confirms the prerequisites for using OpenAI Playground and performs necessary account setup.
1. OpenAI Account Creation/Login
- Access OpenAI Platform
- Navigate to the account creation screen from "Sign up"
- Enter required authentication information such as email address and password, and perform email verification
- Enter your name, date of birth, Organization name, and "What best describes you?"
- Fill in "Invite your team" and "Make your first API call" according to your situation
- For "Add some API credits", click "I'll buy credits later" as we'll set this up later
Registration is now complete.
2. Payment Method Setup (Required)
Setting up a payment method is required to use OpenAI Playground.
- Log in to OpenAI Platform
- Click the account icon in the upper right and select "Your Profile" from the displayed menu
- Select "Billing" from the side menu
- Add a valid credit card from "Add payment details" and charge credits
3. Confirm OpenAI Playground Access
- Access OpenAI Playground
- Confirm that the chat screen displays normally
- Send a simple message to confirm availability
Step 4: Operation Verification with AI Services
Currently, only operation verification with OpenAI Playground is supported.
OpenAI Playground
- Access OpenAI Playground
- Click Create... in the Tools section
- Select MCP Server
- Select Add New
- Enter values in the displayed form:
- URL: The MCP Server endpoint you noted down
- Label: Any label
- Authentication: Select Custom headers
- Key: x-api-key
- Value: The API key you noted down
- Click Connect
- Upon success, a list of available APIs will be displayed in Tools
- Click Add
- Confirm that the added MCP Server is displayed in the Tools section
Step 5: API Call Test from AI Services
OpenAI Playground
- In the chat, enter "Tell me what operations are available with (MCP Server name)"
- When you receive a response saying "Retrieves inventory information for a specific tenant based on the given inventory ID", instruct it to retrieve inventory information by providing the inventory ID
- When the API to call and "Approve" button are displayed, click it
- Confirm if the response is as expected
Step 6: Error Troubleshooting
Common Issues and Solutions
1. Cannot connect to MCP Server
Symptom: AI service cannot connect to MCP Server
Solution:
- Confirm that the API Key is set correctly
- Check network connection
2. API call fails
Symptom: API calls via MCP Server result in errors
Solution:
- Confirm that the API published via Smart API Gateway feature works normally without going through MCP Server
- Check API Key permission settings
- Check if throttling limits have been reached
3. Tools not displayed
Symptom: Tool list is not displayed in AI service
Solution:
- Confirm that the API is normally published via Smart API Gateway feature
- Clear browser cache and retry
