I've been unable to create an MCP server despite meeting the pre-requisite requirements. When creating the MCP server from API, I am met with error:

Parsing error(s): An error occured while parsing the input. Message: Error converting value "mcp" to type 'Microsoft.Azure.ApiManagement.Management.Contracts.ApiTypeContract'. Path 'type', line 2, position 15.

This was reproduced across multiple different APIMs, APIs, subscriptions and locations. Could there be something I've overlooked, or is this feature not ready?

     I'm trying to set up an MCP server and I'm getting the same error as  Benlewis9000​.

    "... Parsing error(s): An error occurred while parsing the input. Message: Error converting value "mcp" to type 'Microsoft.Azure.ApiManagement.Management.Contracts.ApiTypeContract'. Path 'type', line 2, position 15. ..."

    Do you have any idea what this error could be related to?

      After a bit of configuration, it worked 👍. I had to switch the Developer tier to Basic in API Management, and I also configured the AI Gateway Early in the Service updates (preview).

        I am getting the same error, and the tier is Standard.
