Aggregate MCP tools from multiple AI MCP Proxy plugins

This is a Konnect tutorial and requires a Konnect personal access token.

1. Create a new personal access token by opening the Konnect PAT page and selecting Generate Token.

2. Export your token to an environment variable:

    export KONNECT_TOKEN='YOUR_KONNECT_PAT'
   

   Copied!

3. Run the quickstart script to automatically provision a Control Plane and Data Plane, and configure your environment:

    curl -Ls https://get.konghq.com/quickstart | bash -s -- -k $KONNECT_TOKEN --deck-output
   

   Copied!

   This sets up a Konnect Control Plane named quickstart, provisions a local Data Plane, and prints out the following environment variable exports:

    export DECK_KONNECT_TOKEN=$KONNECT_TOKEN
    export DECK_KONNECT_CONTROL_PLANE_NAME=quickstart
    export KONNECT_CONTROL_PLANE_URL=https://us.api.konghq.com
    export KONNECT_PROXY_URL='http://localhost:8000'
   

   Copied!

   Copy and paste these into your terminal to configure your session.

This tutorial requires Kong Gateway Enterprise. If you don’t have Kong Gateway set up yet, you can use the quickstart script with an enterprise license to get an instance of Kong Gateway running almost instantly.

1. Export your license to an environment variable:

    export KONG_LICENSE_DATA='LICENSE-CONTENTS-GO-HERE'
   

   Copied!

2. Run the quickstart script:

   curl -Ls https://get.konghq.com/quickstart | bash -s -- -e KONG_LICENSE_DATA 
   

   Copied!

   Once Kong Gateway is ready, you will see the following message:

    Kong Gateway Ready
   

decK is a CLI tool for managing Kong Gateway declaratively with state files. To complete this tutorial, install decK version 1.43 or later.

This guide uses deck gateway apply, which directly applies entity configuration to your Gateway instance. We recommend upgrading your decK installation to take advantage of this tool.

You can check your current decK version with deck version.

For this tutorial, you’ll need Kong Gateway entities, like Gateway Services and Routes, pre-configured. These entities are essential for Kong Gateway to function but installing them isn’t the focus of this guide. Follow these steps to pre-configure them:

1. Run the following command:

   echo '
   _format_version: "3.0"
   services:
     - name: mcp-service
       url: http://host.docker.internal:3000
     - name: weather-service
       url: https://api.weatherapi.com/v1/current.json
     - name: freecurrency-service
       url: https://api.freecurrencyapi.com/v1/latest
   routes:
     - name: mcp-route
       paths:
       - "/marketplace"
       service:
         name: mcp-service
     - name: weather-route
       paths:
       - "/weather"
       service:
         name: weather-service
     - name: freecurrency-route
       paths:
       - "/currency"
       service:
         name: freecurrency-service
     - name: listener-route
       paths:
       - "/mcp-listener"
   ' | deck gateway apply -

To learn more about entities, you can read our entities documentation.

Before setting up the first AI MCP Proxy plugin, you need an upstream HTTP API. For this tutorial, use a simple Express-based mock API that simulates a small marketplace with users and their orders. It exposes /marketplace/users and /marketplace/{userId}/orders endpoints.

Run the following to download and start the mock API:

curl -s -o api.js "https://gist.githubusercontent.com/subnetmarco/5ddb23876f9ce7165df17f9216f75cce/raw/a44a947d69e6f597465050cc595b6abf4db2fbea/api.js"
npm install express
node api.js

Verify it’s running:

curl -X GET http://localhost:3000

You should see:

{"name":"Sample Users API"}%

1. Go to WeatherAPI.
2. Navigate to your dashboard and copy your API key.
3. Export your API key by running the following command in your terminal:

   export DECK_WEATHERAPI_API_KEY='your-weatherapi-api-key'
   

   Copied!

1. Go to FreecurrencyAPI.
2. Sign up for a free account.
3. Navigate to your dashboard and copy your API key.
4. Export your API key by running the following command in your terminal:

   export DECK_FREECURRENCYAPI_API_KEY='your-freecurrencyapi-api-key'
   

   Copied!

This tutorial uses the MCP Inspector which helps you explore and debug MCP servers.

1. Ensure you have Node.js and npm installed. If needed, download them from https://nodejs.org.

2. Update npx to the latest version:

    npm install -g npx
   

   Copied!
3. Then install the Inspector:

    npm install -g @modelcontextprotocol/inspector
   

   Copied!

This tutorial uses Cursor as an MCP client:

1. Go to the Cursor downloads page.
2. Download the installer for your operating system.
3. Install Cursor on your machine.
4. Launch Cursor and sign in to your account or create a new account.
