Vault Cortex MCP Server

Bearer token for MCP client authentication. Must match the Authorization header sent by clients. Generate with: openssl rand -hex 32

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.

Enable or disable the embedding pipeline. When false, no ONNX model is downloaded, no vector tables are created, and search uses FTS5 only.

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 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.

Enable or disable the structured memory layer. When false, memory tools are hidden, bootstrap is skipped, and server metadata omits memory references.

Enable or disable file tools (vault_read_file, vault_list_files). When false, file tools are hidden and server metadata omits file tool references.

Run the server read-only: every vault-writing tool is hidden, the memory folder is not auto-created, and server metadata omits write references.

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.

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.

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, falling back to "Daily Notes".

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".

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.

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.

IANA timezone for timestamps and daily note resolution.

Logging verbosity.

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.

Days to keep log files before automatic cleanup on startup; only applies when LOG_DIR is a path.

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). When set, overrides the default entirely.

Comma-separated vault folder names excluded from vault_find_orphans. Default: DAILY_NOTES_FOLDER (else "Daily Notes"), "Templates", MEMORY_DIR.

Override the OAuth service documentation URL exposed via discovery metadata.

Largest file vault_read_file will read, in bytes. Reading a larger file returns an error instead of content.

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.

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.
