Interoperable user memory across Orchestrate and other AI agent platforms

Watsonx Orchestrate user memory should interoperate with memory stores used by other AI agents and platforms.

Problem 1 : Missing relevant memories . Users may interact with an agent through Watsonx Orchestrate, and also through other interfaces which pass through a different agent platform to reach the same agent. The memory is maintained separately in each platform. 

Problem 2: Different geneal context for the user.  Over time both platforms will gather different memories of the user according to the conversations had while in their domain. This will mean that the platform's overall undertanding of the user by the user memory contect will be different. This will lead to the user preferring one entry point ove the other as it will seem to know them better.  

see attaced doc for a diagram illustrating the above problms

Problem summary: If each platform maintains isolated user memory, the same user may receive different personalisation, context, and continuity depending on their entry point. 

The request is for Orchestrate to support some form of user-memory interoperability. This would improve consistency of user experience, reduce fragmented context, and support coherent multi-agent ecosystems where memory follows the user, not just the interface.

However it is implemented is fine:

• Support user memory as an MCP-based service so Orchestrate can read/write governed user memory from approved external memory services
• or Extend A2A so agents can advertise whether they support user-memory exchange, and negotiate what memory can be shared, queried, or updated. 
• or Adopt a services like OpenMemory / Mem0
• or lean in on agent mmemory protocol (though this sounds a long road)
