[Hedda]

Anyone on/from the OpenVoiceOS project working on Model Context Protocol (MCP) server/proxy support and integration as an AI interface?

For reference; here is a video that explains how Model Context Protocol (MCP) works and why it will be key to standardizing Agentic AI:

Recommend read how the Open Home Foundation and Home Assistant's founders describe idea/concept of AI agents for the smart home:

Relevant to this is that Home Assistant 2024.2 release added support for "Model Context Protocol" (MCP) server and client that will eventually be used to extend Home Assistant's AI capabilities through file access, database connections, API integrations, and other contextual services:

FYI, Paulus Schoutsen (Home Assistant founder) spoke about MCP during the Home Assistant 2025.2 release party video, check out his explaination (starting at timestamp 56:40):

And their voice development team also spoke about it on the Voice Chapter 9 video:

Also see MCP mentioned in this blog article about Home Assistant's voice assistant development:

For development and testiing follow this TL;DR on Home Assistant's Model Context Protocol integration (made by allenporter):

Home Assistant (which is now by the top open-source project by contributers) already features some AI tooling as well as many integrations for many LLMs as conversation agents, but they to not provide specific AI tooling such as the "Patterns" that Fabric provide.

• https://www.home-assistant.io/integrations/google_generative_ai_conversation/

Today the AI integrations are for LLMs that normally just use Home Assistant's "Conversation integration" and at most integrate with Home Assistant's "Assist" (Home Assistant's voice assistant pipeline) via its "sentence trigger" to trigger automations.

AI conversation support for Assist in Home Assistant has however signifigantly improved over the past 6-months or so.
