APIM MCP Server Fails to Handle Both URL Parameters and JSON Body in the Same Request

We are experiencing an issue with the MCP server where it does not handle both URL parameters and a JSON body simultaneously in requests. This issue occurs specifically when the request has the header:

**Observations:**
-> When a request is sent with Content-Type: application/json and includes a JSON body, URL parameters like cartId are not visible in the MCP Inspector.

-> If the JSON body is removed, the URL parameters like cartId is correctly recognized.

-> Based on inspection using MCP Inspector, this behavior confirms that MCP only handles one input source at a time (either URL parameters or JSON body, but not both).

**Impact:**
This prevents sending valid requests that include both a required URL parameter and a JSON body payload. As a result, requests fail or behave incorrectly due to missing required parameters.
