Hi there,

I built an MCP Proxy App/Add-on based on https://github.com/sparfenyuk/mcp-proxy, which can be used to bridge typical stdio MCPs to SSE so that Assist Conversation Agent can use it.

I currently use it to expose OpenWeatherMap, Wikipedia and a calculator tool to HA Assist.

Here is the GitHub Repo with installation instructions, changelog and releases:

Additionally here is my sample servers.json with the mentioned MCP Servers configured:

{
  "mcpServers": {
    "calculator": {
      "command": "uvx",
      "args": ["mcp-server-calculator"]
    },
    "openweathermap2": {
      "command": "npx",
      "args": ["-y", "@tristau/openweathermap-mcp", "--apikey", "OWM API KEY"]
    },
    "wikipedia-us": {
      "command": "uvx",
      "args": [
        "wikipedia-mcp",
        "--country",
        "US"
      ]
    },
    "wikipedia-de": {
      "command": "uvx",
      "args": [
        "wikipedia-mcp",
        "--country",
        "DE"
      ]
    }
  }
}

Would be curious to get feedback / feature requests / contributions if you think this is useful :handshake:
