Self-hosted semantic memory over MCP for an engineering team's tacit knowledge. Needs Postgres.
Tribal is an MCP integration. Self-hosted semantic memory over MCP for an engineering team's tacit knowledge. Needs Postgres.
The published oci package is ghcr.io/tribal-memory/tribal:0.4.1. Its declared MCP transport is streamable-http.
The package declares 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: Optional; only if an ingest or retrieval stage is configured to use OpenAI (defaults target a local Ollama).; ANTHROPIC_API_KEY: Optional; only if a stage is configured to use Anthropic..
This package has launch arguments in its registry record. Use the maintainer’s configuration for those arguments rather than launching it with only the package name.
Check the maintainer’s instructions for account access, authentication and the supported client configuration. Once connected, inspect the tools your client receives and try a small task that matches the server’s stated purpose. The registry description does not include a verified, complete tool list.
