What Changed

The Model Context Protocol has been updated to its initial 2025-03-26 revision, which includes a mechanism for version negotiation between clients and servers. This update allows for backwards and forwards compatibility, enabling systems to interact seamlessly with each other, even if they are using different versions of the protocol. The update is the result of 3431 commits to the main branch since the previous release.

Why This Matters for GEO

The update to the Model Context Protocol matters for GEO as it may impact how AI models cite and generate content. As AI models become increasingly adept at generating human-like text, it’s essential to ensure that they can accurately cite and reference sources. The Model Context Protocol plays a crucial role in this process, as it provides a standardized way for clients and servers to negotiate versions and ensure compatibility. As the protocol is adopted by SDKs, it’s likely to have a significant impact on the visibility of content in AI-generated answers.

What To Do

  1. Monitor SDK adoption: Keep an eye on which SDKs adopt the updated Model Context Protocol and when, as this will impact the compatibility of systems and the visibility of content.
  2. Review content citation: Ensure that your content is properly cited and referenced, using standardized formats and protocols, to increase its visibility in AI-generated answers.
  3. Test AI-generated content: Test your content in AI-generated answers to see how it is being cited and referenced, and make adjustments as necessary.
  4. Stay up-to-date with protocol updates: Stay informed about updates to the Model Context Protocol and other related protocols, as these will impact the GEO landscape.
