Aggregate MCP tools from conversion-only mode plugins
Listener mode works together with conversion-only mode:
- Configure one or more Routes with the plugin in
conversion-onlymode. Eachconversion-onlyRoute defines tools and assigns them atags[]value. -
Configure a separate Route for the plugin in the
listenermode:services: - name: mcp-service url: http://host.docker.internal:3000 routes: - name: mcp-listener paths: - /mcp-listenerCopied!Before using the AI MCP Proxy plugin, you’ll need an upstream HTTP API to expose. Use this mock API to test the plugin without relying on an external service; it simulates a small marketplace with sample users and orders exposed through

- At least one Route with the plugin in
conversion-onlymode, tagged at the plugin level with the same value asconfig.server.tag
