}- TRIBAL_DATABASE__URLrequiredPostgres (pgvector) connection string. Tribal is self-hosted; you provide the database. The supported, complete deployment is docker-compose.yml.
- TRIBAL_PROJECT_REMOTErequiredFirst-run only: the git remote that identifies the project bootstrapped on first start.
- TRIBAL_PROJECT_NAMErequiredFirst-run only: the name of the project bootstrapped on first start.
- TRIBAL_SERVER__TRANSPORTContainerised transport: http or sse. The Docker image does not serve stdio; install the binary for stdio.
- TRIBAL_SERVER__BIND_ADDRESSAddress the server binds inside the container. Must be 0.0.0.0 (not the loopback default) for the published port to be reachable.
- TRIBAL_PUBLIC_MCP_URLThe URL clients use to reach the server (for example http://127.0.0.1:8725/mcp). Needed for OAuth dynamic client registration once the server binds a routable interface.
- OPENAI_API_KEYsecretOptional; only if an ingest or retrieval stage is configured to use OpenAI (defaults target a local Ollama).
- ANTHROPIC_API_KEYsecretOptional; only if a stage is configured to use Anthropic.
A starting point — check the repository for exact arguments and setup. Restart your client after editing the config.
