Tools

This server runs locally, so its tools are listed by your MCP client once it starts.

Environment variables

Name	Description
`DATABASE_URL` Required, secret	PostgreSQL 16 + pgvector (0.8.0+) connection URL for the app's NON-superuser role, e.g. postgresql+asyncpg://obsidian_mcp:<password>@postgres:5432/obsidian_mcp. A superuser role or a CHANGE_ME password is refused at startup.
`VAULT_PATH` Required	Path of the Obsidian vault inside the container (mount your vault read-write there).
`SECRET_KEY` Required, secret	itsdangerous signer for cookies/sessions. Generate with `openssl rand -hex 32`; the app refuses to start on a placeholder.
`MCP_HOSTNAME` Required	Public hostname your reverse proxy routes to. Also derives BASE_URL, ALLOWED_ORIGINS and ALLOWED_HOSTS as https://<MCP_HOSTNAME> unless those are set explicitly.
`EMBEDDING_PROVIDER` Optional	Embedding provider: `ollama` (self-hosted, default), `openai` (bring your own key) or `tei` (Hugging Face Text Embeddings Inference, native /embed). Switching after deploy requires `make reset-embeddings`.
`OLLAMA_URL` Optional	Ollama endpoint serving bge-m3 (used when EMBEDDING_PROVIDER=ollama). Must be https or loopback unless EMBEDDING_ALLOW_PLAINTEXT is set.
`OPENAI_API_KEY` Optional, secret	OpenAI (or OpenAI-compatible) API key for text-embedding-3-* (required when EMBEDDING_PROVIDER=openai; the server refuses to start without it).
`TEI_URL` Optional	TEI endpoint (used when EMBEDDING_PROVIDER=tei). Must be https or loopback unless EMBEDDING_ALLOW_PLAINTEXT is set.
`TEI_EMBEDDING_MODEL` Optional	Must equal the model_id the TEI server reports at GET /info, exactly (a local path included); a different value refuses startup. A change needs `make reset-embeddings`.
`TEI_EMBED_BATCH_SIZE` Optional	Inputs per TEI /embed request (1-256). A value above the server's max_client_batch_size refuses startup.
`TEI_API_KEY` Optional, secret	Bearer token for a TEI server started with --api-key; sent only to TEI_URL (/embed, /info, the panel's /health). Empty means no Authorization header.
