FME 2026.3 MCP writer missing "Structured Content" ?

Hi ​@lifalin2016, 

I believe you were likely watching the “From Esri to AI: Create an MCP Server in 7 Minutes with FME” webinar. The version of FME Workbench shown in the webinar was an internal beta build, which included Structured Content before FME 2026.2 was finalized for release. 

Apologies for the confusion and any inconvenience this has caused! 
 
Looking at the internal development ticket that tracks support for Structured Content, it appears to be currently targeted for the FME 2027.1 release. Please note that the targeted version may change as development progresses. 

If you're running into specific issues in your MCP implementation, I'd suggest creating a new post. The community or our team at Safe might be able to help with more context as to what you're getting stuck on!

I know you mentioned you couldn't upload an image for this post. File uploads should now be working again in the Community!

Thanks Abby.

Yes, I just saw that particular webinar. I’m somewhat disappointed that this functionality (and thereby testing MCP fully) is not available until 2027.1, especially since it’s being promoted as we speak.

Are there any resources for 2026.x that explains how to setup MCP services with the (in 2026.3) available MCP Writer feature types?

Hi ​@lifalin2016, 

I completely understand the disappointment. Thank you for bringing this to our attention, and I have shared this feedback with our team.

We do have tutorials and demos available that cover the Text Content, Image Content, Resource Link and Embedded Resource feature types, which I have listed below.

At this time, there isn’t a dedicated Audio Content tutorial, but like Image Content, audio is passed to the writer as Base64-encoded data with a MIME type. More information can be found here:

As a workaround for the Structured Content feature type, you should be able to return JSON from your workspace using the Text Content feature type. The “Returning Text Content from an FME MCP Tool” article is a good starting point for this. What Structured Content will add is an output schema that describes the JSON to the agent. 

I’d like to create a ticket on your behalf regarding this topic so that you will be notified as soon as Structured Content is made available! You should receive an email from Safe Support shortly.
