Discussion Topic

I have to build a REST API service and add an MCP (Streamable HTTP) server as well to expose the services for MCP Client. Considered the below approaches. Couldn't find any best practices or examples around this. So any suggestions on this are welcome.

• Separate WebApp instances / service for REST API and MCP Server running. Both of them sharing the common business logic.
• Single Host Service with both REST API and MCP server added to it.
• MCP server as a wrapper around REST API ie. Tools in MCP server would inturn call the REST API
