opencode-muse-code

Use a Muse Code (Meta) subscription in OpenCode.

The plugin reads the login the muse CLI
already stored on your machine, registers a muse-code provider that talks to
https://api.meta.ai/v1, and discovers the available Muse models on startup and
every 30 minutes. Model requests are metered by Meta against your Muse Code
subscription — OpenCode needs no API key in its own configuration.

Features

• Zero configuration once the muse CLI is signed in.
• Live model discovery with real context/output limits, tool support, input
  types, and reasoning-effort variants.
• Reads credentials from the macOS keychain (or ~/.config/muse/auth.json),
  with META_API_KEY / MUSE_API_KEY and an explicit key option as
  fallbacks.
• Never writes credentials to OpenCode configuration or the repository.

Requirements

• OpenCode V2 (tested on 2.0.8).
• The muse CLI installed and signed in — run muse once if you have not.
• An active Muse Code subscription. Check with the muse CLI or the
  Muse Code page.

Install

opencode plugin add opencode-muse-code

Or add it to the plugins list in opencode.jsonc yourself:

{
  "plugins": ["opencode-muse-code"]
}

Pin a version if you prefer:

{
  "plugins": ["opencode-muse-code@0.1.2"]
}

Restart the service after changing configuration:

opencode service restart

git clone https://github.com/swalker326/opencode-muse-code.git

{
  "plugins": ["/absolute/path/to/opencode-muse-code"]
}

Or copy the folder to ~/.config/opencode/plugins/muse-code/, where plugin
directories load automatically.

Use

Pick a model with /models in the TUI, or run one directly:

opencode run --model muse-code/muse-spark-1.3 "Summarize this repository"

Models

Models are discovered from Meta's catalog, so t
