Configuration · Trina AX Docs

The server.json file, the MYCEL_ environment variables, and the Anthropic-compatible gateway.

Use the installer and the Admin screens first. server.json is for the operator's deployment settings, not for team documents or secrets.

The schema is in server/src/app-config.ts.
Environment variables win over the file.
On Linux the file is /var/lib/mycel/config/server.json. Restart with sudo systemctl restart mycel-server after a change.

#Common settings

Settings come from two places. Environment variables win over the file.

Variable	What it does
`MYCEL_CONFIG` or `--config`	The server JSON path. Prevents picking another installation by accident.
`MYCEL_MODE`	`dev` or `prod`. Changing it alone does not install OS isolation.
`MYCEL_HOST`, `MYCEL_PORT`	Where the server listens. Loopback by default.
`MYCEL_DATA_DIR`, `MYCEL_TEAM_ROOT`	The database and private runtime folder, and the team-file folder. Keep them separate.
`MYCEL_PUBLIC_ORIGINS`	Comma-separated browser origins of the installation. A wrong host or port causes cookie and origin errors.
`MYCEL_LOG_LEVEL`	`debug`, `info`, `warn` or `error`.
`MYCEL_EXIT_ADDRESS_CHECK`	`off` stops the server asking the release feed for its own public address. Then every web address the AI opens needs a person.

On Linux, put environment overrides in /etc/default/mycel.

Key	What it does
`engine.authMode`	`local-login` uses the OS user's CLI login. `managed` uses AI connections behind the model proxy.
`engine.credentialKinds`	Narrows which connection kinds the team may add.
`engine.anthropicGateway`	Runs Claude Code on other models. See below.
`appConnectors`	`true` with `tunnel.host` turns on the MCP connector.
`relay`, `tunnel`, `update`	Address and update-feed settings. Keep what the installer wrote.

See every variable and key.

#Anthropic-compatible gateway

Claude Code can answer with other companies' models through an address that speaks Anthropic's Messages API: OpenRouter, or the Anthropic-compatible APIs of DeepSeek, Moonshot (Kimi) and Zhipu (GLM). The sandbox and folder permissions stay the same. Only the model behind the proxy changes.

"engine": {
  "authMode": "managed",
  "anthropicGateway": {
    "baseUrl": "https://openrouter.ai/api",
    "label": "OpenRouter",
    "models": { "default": "deepseek/deepseek-v4-pro", "haiku": "deepseek/deepseek-v4-flash" }
  }
}

Warning

With a gateway, every Claude Code request goes to the gateway provider and the model's vendor. Claude subscription connections are off while it is set. Check both providers' terms and tell the team.

Then add the gateway's key in Admin › AI connections. Full rules: Configuration.

`axserver`, `axagent`	Service accounts and file ownership
`@mycel/`, `TEAM_AX_DEV_`	Source packages and development settings
