What is measured is what a manifest declares, not what a piece of software does. This registry fetches no repository URL, no endpoint and no package index; nothing here is verified. Which value comes from which source, and by which rule it was formed, is set out in the Methodology.

Environment variable descriptions (raw)ANTHROPIC_API_KEY=Optional; only if a stage is configured to use Anthropic. · OPENAI_API_KEY=Optional; only if an ingest or retrieval stage is configured to use OpenAI (defaults target a local Ollama). · TRIBAL_DATABASE__URL=Postgres (pgvector) connection string. Tribal is self-hosted; you provide the database. The supported, complete deployment is docker-compose.yml. · TRIBAL_PROJECT_NAME=First-run only: the name of the project bootstrapped on first start. · TRIBAL_PROJECT_REMOTE=First-run only: the git remote that identifies the project bootstrapped on first start. · TRIBAL_PUBLIC_MCP_URL=The 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. · TRIBAL_SERVER__BIND_ADDRESS=Address the server binds inside the container. Must be 0.0.0.0 (not the loopback default) for the published port to be reachable. · TRIBAL_SERVER__TRANSPORT=Containerised transport: http or sse. The Docker image does not serve stdio; install the binary for stdio.

The image is drawn again on every request, so it always reports the current state while the pasted line stays as it is. It carries no rating and no traffic light – only the two measured figures.
