mcp-trove-crunchtools
Self-hosted local file indexing MCP server with semantic search. Index any local directory (pCloud ~/AutoSync/, rclone mounts, ~/Documents/, anything) and search over the contents using hybrid vector + keyword search.
Features
- Hybrid search — Combines semantic vector similarity with FTS5 keyword matching
- Multiple file formats — PDF, DOCX, Markdown, plain text, source code
- Local-first — No cloud services, no per-seat fees, your data stays on your machine
- Lightweight embeddings — Uses fastembed (ONNX runtime) instead of PyTorch (~22MB vs ~2GB)
- Incremental indexing — SHA-256 checksum-based change detection
- Background mode —
--indexCLI mode for systemd timer automation

Tools (10)
Search (2)
| Tool | Description |
|---|---|
trove_search |
Hybrid semantic + FTS5 search. Returns ranked chunks with file paths, scores, and content. |
trove_similar |
Find files similar to a given indexed file using its average embedding. |
Index Management (3)
| Tool | Description |
|---|---|
trove_index |
Index a specific file or directory. Skips unchanged files (checksum-based). |
trove_reindex |
Force re-index ignoring checksums. If no path given, reindexes everything. |
trove_remove |
Remove a file or directory from the index. |
Status (5)
| Tool | Description |
|---|---|
trove_status |
Index statistics: total files, chunks, disk usage, model info. |
trove_list |
List indexed files with metadata (size, type, chunk count). |
trove_get_chunks |
Show the text chunks for a specific indexed file. |
trove_log |
Activity log of indexing runs: start/finish times, file counts, errors. Persisted in SQLite, survives container crashes. |
trove_quality |
Per-file error tracking from indexing runs: which files failed, why, and whether a later index resolved it. |
Environment Variables
| Variable | Default | Description |
|---|---|---|
TROVE_DB |
~/.local/share/mcp-trove/trove.db |
SQLite database path |
TROVE_PATHS |
(none) | Directories to index in background mode, separated by : (; on Windows) |
TROVE_INDEX_WORKERS |
20 |
Concurrent embedding workers |
TROVE_INDEX_BATCH |
50 |
Files per indexing batch |
TROVE_EMBEDDING_MODEL |
BAAI/bge-small-en-v1.5 |
fastembed model name |
TROVE_EXCLUDE_PATTERNS |
*.iso,*.zip,... |
Glob patterns to skip |
TROVE_CHUNK_SIZE |
1000 |
Characters per text chunk |
TROVE_CHUNK_OVERLAP |
200 |
Overlap between chunks |
TROVE_PDF_MAX_PAGES |
5 |
Pages indexed from the start of each PDF, enough to tell what the document is about while keeping memory flat on large manuals; 0 or negative indexes every page |
TROVE_MAX_TEXT_CHARS |
5000000 |
Characters of extracted text kept per file; the rest is dropped with a warning so one huge document cannot flood a batch with chunks; must be positive, other values fall back to the default with a warning |
TROVE_VISION_BACKEND |
none |
Vision captioning backend: gemini, openai, openrouter, ollama, or none to disable |
TROVE_VISION_MODEL |
per backend | Vision model. Defaults to gemini-2.5-flash, gpt-4o-mini, google/gemini-3.1-flash-lite (openrouter) or llava depending on the backend; empty when disabled |
TROVE_VISION_PROMPT |
(see below) | Caption prompt sent with each image |
TROVE_VISION_TIMEOUT |
120 |
Seconds allowed per vision API call |
Image and video captioning is off until TROVE_VISION_BACKEND is set. The
openrouter backend reads OPENROUTER_API_KEY_FILE or OPENROUTER_API_KEY,
handles video as well as images, and only routes to zero-retention providers. The
default caption prompt is:
Generate a concise caption for this image suitable for search indexing. Include: what you see, location if identifiable, time of day, any readable text or signs.
Background Indexing
Set up a systemd timer to keep your index fresh:
TROVE_PATHS=~/Documents:~/AutoSync mcp-trove-crunchtools --index
