agent-notify

Local spoken notifications for Codex. Each message plays through your speakers and appears in a small always-on-top overlay.

Install

Requires Python 3.11 and uv.

uv sync
uv run --no-sync agent-notify-setup
codex mcp add agent-notify -- "$(pwd)/.venv/bin/tts-mcp"

Restart Codex, then run /mcp to check that agent-notify is connected. The setup command downloads and loads the voice model, then opens a real test notification. Its generated audio is cached for later runs.

Upgrading from the earlier tts.speak tool:

codex mcp remove tts
codex mcp add agent-notify -- "$(pwd)/.venv/bin/tts-mcp"

Turn TTS on or off

Use the TTS ON / TTS OFF button in any notification window. Your choice is saved and applies to future messages; muted messages remain visible so you can turn speech back on. Turning TTS off also stops the message currently playing, and the muted window remains open for 15 seconds. A small bar at the bottom shows the remaining display time. Use the pause button beside the bar to keep a notification open, then resume the remaining countdown or close it manually.

You can also use the terminal:

uv run tts-config off
uv run tts-config on
uv run tts-config status

Try it

uv run tts-notify \
  '{"type":"agent-turn-complete","last-assistant-message":"TTS is ready."}'

Test

uv run pytest

Optional settings

Set these environment variables when registering the server with codex mcp add ... --env NAME=VALUE:

• TTS_MCP_MODEL — Coqui model name

• TTS_MCP_SPEAKER — speaker ID for a multi-speaker model

• TTS_MCP_OUTPUT_DIR — directory for cached WAV files

• TTS_MCP_OVERLAY=off — play audio without the overlay

The default model is tts_models/en/jenny/jenny. Audio continues to work when no graphical display is available.
