Hume MCP Server

What it does

Hume's official MCP server drives Octave, a speech-language model that performs text rather than merely pronouncing it, with prompt-directed emotion and delivery. Ideal for film dialogue and narration where acting nuance matters; agents can iterate on takes, save designed voices to a library, and replay prior audio without regenerating.

Sample tools

Field notes

Official but effectively dormant, and the gap keeps widening: npm @humeai/mcp-server is still 0.3.0, published 8 Jan 2026 — over eight months with no release. The GitHub repo reports a push on 26 Aug 2026, but that is not the default branch: the newest commit on main is still 'bump v (#17)' from 8 Jan 2026, so read the push date as branch noise, not maintenance. ~9 stars, 3 open issues, no LICENSE file in the tree even though npm metadata declares ISC. Hume's docs site also serves a separate MCP at https://dev.hume.ai/_mcp/server, but that is Mintlify documentation search (one searchDocs tool) — it will not synthesize a line of dialogue, so do not wire it in expecting Octave. Five tools — a much narrower surface than ElevenLabs or Cartesia, and TTS-only, so pair it with something else for SFX and transcription. Set --workdir/-w (or WORKDIR) or audio lands in the system temp directory under /hume-tts; local playback wants ffplay or another CLI player on PATH. EMBEDDED_AUDIO_MODE (default false) returns audio inline instead, which is what you want in a client that cannot reach your filesystem.
