Brainiall Pronunciation is a remote MCP server that gives an AI agent 14 tools, among them assess_pronunciation, check_pronunciation_service, check_stt_service. It answers at https://api.brainiall.com/mcp/pronunciation/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 7 of 10 times since 4 September 2026; the last check, on 18 October 2026, succeeded.
Pronunciation assessment, phoneme scoring, speaker voice ID, audio transcription, speech synthesis.
