Self-hosted semantic memory over MCP for an engineering team's tacit knowledge. Needs Postgres.

Trust verdict · v1 advisory · method
NOT YET SCREENEDno verdict on file

Verdict not yet evaluated for this tool. The semantic screen takes adversarial cases first; coverage rolls out as the corpus expands (15/150 labels to graduation). The deterministic conformance probe is built but has not yet run on the public corpus, so a recorded verdict here is REVIEW or UNVERIFIED, never a clearing ALLOW. Until a verdict is recorded, an agent should treat this tool as not-yet-cleared and fall back to its own checks. Method: the eval, four-state verdict, honest limits.

Environment variables
TRIBAL_DATABASE__URL
required

Postgres (pgvector) connection string. Tribal is self-hosted; you provide the database. The supported, complete deployment is docker-compose.yml.

TRIBAL_PROJECT_REMOTE
required

First-run only: the git remote that identifies the project bootstrapped on first start.

TRIBAL_PROJECT_NAME
required

First-run only: the name of the project bootstrapped on first start.

TRIBAL_SERVER__TRANSPORT

Containerised transport: http or sse. The Docker image does not serve stdio; install the binary for stdio.

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_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.

OPENAI_API_KEY
secret

Optional; only if an ingest or retrieval stage is configured to use OpenAI (defaults target a local Ollama).

ANTHROPIC_API_KEY
secret

Optional; only if a stage is configured to use Anthropic.
