Answer 1

Hello

Thanks for reaching out on Microsoft Q&A and really appreciate your patience while we looked into this.

Understand from description that you're having an issue with the APIM MCP Server (preview) where the contents of the body aren't being recognized when using the mcp tool.

Steps:

Check API Management Configuration: Ensure that your API in Azure API Management is properly configured to handle inbound requests. Verify that any related policies (like IP filtering, authentication, or request transformations) are set up correctly and not blocking or modifying the requests in unintended ways.

Monitor Logs: Use Azure Monitor or Application Insights to review the logs related to your MCP server. This can help identify any issues with the requests being processed. Look for correlations and errors that might give you more context on what’s happening.

Test with Debug Tools: Consider using tools like the MCP Inspector or other debugging capabilities (like API Inspector) to test the endpoints directly. This will help you verify if the issue lies within the MCP server configuration or in the way requests are structured.

Validation of Payload Structure: Make sure that the payload (the body of the request) conforms to the expected format required by the MCP server. Any mismatch might lead to the server not recognizing the contents.

Review Documentation for Limitations: Since MCP features are in preview, be aware of any limitations outlined in the Azure documentation that might apply to your setup.

Please provide the below information, if still issue persists.

1. Can you provide details on the specific error messages or any logs that seem relevant when trying to call the MCP tool?
2. What steps have you already taken to troubleshoot this issue?
3. Are you using any specific API Management policies that might impact the request format or handling?
4. Can you describe the structure of the request body you are sending to the MCP server?
