AI MCP Proxy: Generate an MCP server in conversion-listener mode - Plugin

Generate an MCP server in conversion-listener modev3.12+

Generate an MCP server from Kong Gateway Services.

For this configuration to work properly, you need a Service and a Route with the following configuration:
services:
- name: weather-service
  url: https://api.weatherapi.com/v1/current.json
  routes:
  - name: weather-route
    paths:
    - /weather

This example uses config.tools.annotations.title to add a meaningful name to the tool to simplify human debugging.

Prerequisites
