NeuralScio implements newline-delimited JSON-RPC over local stdio and has network HTTP/SSE handling in the desktop MCP server.
stdio
Use --mcp-stdio for a local client. This is the preferred starting point because the client launches the same desktop executable and does not open a network listener.
HTTP and SSE
Use a configured MCP host and port only when a network client is required. Remote access is subject to host, token, TLS, origin, and read/write policy settings. Check MCP Security before exposing a listener.
