Adding MCP Tools to Reachy Mini

The Reachy Mini conversation app can now utilize tools hosted in public Hugging Face Spaces, called over MCP. This allows the robot to gain new abilities, like checking the weather or searching the web, by adding a Space via a command-line interface rather than editing local application code. A model decides which tool to use during a conversation based on a profile that specifies available tools and instructions. This system separates stateless, shareable capabilities like web search from trusted, local tools that control the robot's physical hardware.
