| MCP_AUTH_TOKEN | Yes | Bearer token for MCP client authentication. Must match the Authorization header sent by clients. Generate with: openssl rand -hex 32 Secret. |
| PUBLIC_URL | No | Public URL clients use to reach this server. Used as the OAuth issuer URL in discovery metadata. Override when exposing the server outside localhost or on a non-default port. |
| EMBEDDING_ENABLED | No | Enable or disable the embedding pipeline. When false, no ONNX model is downloaded, no vector tables are created, and search uses FTS5 only. |
| RERANK_MODE | No | Cross-encoder reranking mode: blended (position-aware score blending after RRF fusion) or none (skip reranking). Only takes effect when EMBEDDING_ENABLED is true. |
| WINDOWS_MODE | No | Windows bind-mount mode: enables filesystem polling for the file watcher and rename-based moves across the Docker Desktop/WSL2 bridge. Set to true when the vault lives on a Windows drive. |
| MEMORY_ENABLED | No | Enable or disable the structured memory layer. When false, memory tools are hidden, bootstrap is skipped, and server metadata omits memory references. |
| FILE_TOOLS_ENABLED | No | Enable or disable file tools (vault_read_file, vault_list_files). When false, file tools are hidden and server metadata omits file tool references. |
| READONLY_MODE | No | Run the server read-only: every vault-writing tool is hidden, the memory folder is not auto-created, and server metadata omits write references. |
| DISABLED_TOOLS | No | Hide individual tools by name, comma-separated. Subtractive only — it cannot re-enable a tool another setting hides; an unknown tool name stops the server at startup. |
| MEMORY_DIR | No | Vault folder for structured memory files (About Me-style notes). Memory tools are hidden when MEMORY_ENABLED is false, but this value still feeds the defaults for PROTECTED_PATHS and ORPHAN_EXCLUDE_FOLDERS. |
| DAILY_NOTES_FOLDER | No | Vault folder for daily notes. Overrides the folder configured in Obsidian's daily-notes plugin. When unset, read from the vault's .obsidian/daily-notes.json (an empty folder there follows Obsidian's new-note location), falling back to "Daily Notes" when that file is missing. Set to / for the vault root. |
| DAILY_NOTES_FORMAT | No | Filename date format for daily notes (Moment.js tokens). Overrides the format configured in Obsidian's daily-notes plugin. When unset, read from the vault's .obsidian/daily-notes.json, falling back to "YYYY-MM-DD". |
| TRUST_PROXY_HOPS | No | Number of trusted reverse-proxy hops used to derive the client IP from X-Forwarded-For for OAuth rate limiting and request logs. With 0, injected forwarding headers are ignored. |
| TRUST_FORWARDED_HOPS | No | How many entries from the end of the RFC 7239 Forwarded header's for= list to count to reach the client IP for OAuth rate limiting and request logs. 0 ignores the header; 1 when the proxy in front writes it (e.g. AWS API Gateway); 2 when a CDN fronts that proxy and is the only way to reach it. |
| TZ | No | IANA timezone for timestamps and daily note resolution. |
| LOG_LEVEL | No | Logging verbosity. |
| LOG_DIR | No | Directory for log files that survive container re-creation. The container's own log is always written but discarded when the container is recreated; date-stamped files under LOG_DIR persist on the data volume. Default: /data/logs (remote image), $STORAGE_ROOT/data/logs (single-volume mode), none (local image). none keeps only the container log. |
| LOG_RETENTION_DAYS | No | Days to keep log files before automatic cleanup on startup; only applies when LOG_DIR is a path. |
| PROTECTED_PATHS | No | Comma-separated vault folder names blocked from vault_delete_note and vault_move_note. Default: MEMORY_DIR plus the daily notes folder, read from DAILY_NOTES_FOLDER or .obsidian/daily-notes.json (default Daily Notes; none when that setting is the vault root or empty). When set, overrides the default entirely. |
| ORPHAN_EXCLUDE_FOLDERS | No | Comma-separated vault folder names excluded from vault_find_orphans. Default: the daily notes folder, "Templates", and MEMORY_DIR. DAILY_NOTES_FOLDER wins; otherwise .obsidian/daily-notes.json is read per query (fallback "Daily Notes"; no daily folder when that setting is the vault root or empty). When set, replaces the defaults entirely. Set to a comma (,) to exclude nothing; an empty value uses the defaults. |
| SERVICE_DOCUMENTATION_URL | No | Override the OAuth service documentation URL exposed via discovery metadata. |
| MAX_FILE_BYTES | No | Largest file vault_read_file will read, in bytes. Reading a larger file returns an error instead of content. |
| MAX_IMAGE_OUTPUT_BYTES | No | Byte budget for images returned by vault_read_file, in binary bytes before base64 encoding. Images exceeding the budget are downscaled/recompressed server-side to fit; raise for clients that accept larger tool responses. |
| MAX_PDF_RENDER_PAGES | No | Maximum PDF pages to render as images when raw: true is set on vault_read_file. The per-page byte budget is MAX_IMAGE_OUTPUT_BYTES divided evenly across the rendered pages. |
