quarry
Enables local semantic search over documents and code for Claude Code and Claude Desktop, running entirely offline with local embeddings and vector storage.
README
punt-quarry
Local semantic search for AI agents and humans.
Quarry indexes documents in 20+ formats, embeds them with a local ONNX model (snowflake-arctic-embed-m-v1.5, 768-dim), stores vectors in LanceDB, and serves semantic search to Claude Code, Claude Desktop, and the CLI. Everything runs locally — no API keys, no cloud accounts. The embedding model (~120 MB int8) downloads once on first use. CUDA GPUs are auto-detected for faster inference.
Platforms: macOS, Linux
Quick Start
curl -fsSL https://raw.githubusercontent.com/punt-labs/quarry/35a4b33/install.sh | sh
Restart Claude Code, then:
> /ingest report.pdf # index a document (runs in background)
> /quarry status # after a moment, confirm it's there
> /find "what does the report say about margins" # search by meaning
Once installed, a plugin hook auto-indexes your current project directory on every session start — you don't need to /ingest your codebase manually.

Remote Server
Run quarry on a GPU server and connect from any Mac or Linux client over TLS.
Server (GPU host, serves remote clients):
export QUARRY_API_KEY=$(openssl rand -hex 32)
curl -fsSL https://raw.githubusercontent.com/punt-labs/quarry/35a4b33/install.sh | sh -s -- --network
Generates TLS certificates, binds daemon to 0.0.0.0, registers a systemd service, and prints a CA fingerprint. NVIDIA GPUs are auto-detected for CUDA inference.
Client (connects to remote server):
curl -fsSL https://raw.githubusercontent.com/punt-labs/quarry/35a4b33/install.sh | sh
quarry login <server-hostname> --api-key <token>
No special flag needed --- the default install runs a local daemon on localhost. quarry login redirects queries to the remote server over wss:// with TOFU certificate pinning.
Claude Desktop
Download punt-quarry.mcpb and double-click to install. Alternatively, quarry install configures Claude Desktop automatically.
Note: Uploaded files in Claude Desktop live in a sandbox that quarry cannot access. Use remember for uploaded content, or provide local file paths to ingest.
Features
- 20+ formats --- PDFs (with OCR for scanned pages), source code (AST-aware splitting), spreadsheets, presentations, HTML, Markdown, LaTeX, DOCX, images
- Semantic search --- retrieval is by meaning, not keyword. A query about "margins" finds passages about profitability even if they never use that word
- Daemon architecture --- one
quarry serveprocess loads the embedding model once and serves all Claude Code sessions via mcp-proxy over WebSocket - Passive knowledge capture ---
quarry enablesets up three scoped collections per project: file sync, passive captures (web fetches + session transcripts), and per-agent memory. Captures are separated from the code index so research doesn't pollute code search - Named databases --- isolated LanceDB directories with independent sync registries. Switch with
usefor work/personal separation - Research agent ---
researchersubagent combines quarry local search with web research, auto-ingests valuable findings
What It Looks Like
Ingest a document
> /ingest report.pdf
▶ Ingesting report.pdf (background)
Check what's indexed
> /quarry
▶ Database: default
Documents: 47
Chunks: 1,203
Size: 12.4 MB
Model: snowflake-arctic-embed-m-v1.5 (768-dim)
Search by meaning
> /find "what were the Q3 revenue figures"
▶ [report.pdf p.12 | text/.pdf] (similarity: 0.4521)
Third quarter revenue reached $142M, up 18% year-over-year,
driven primarily by expansion in the enterprise segment.
Gross margins improved to 71% from 68% in Q2.

Setup
Quarry works with zero configuration. These environment variables are available for customization:
| Variable | Default | Description |
|---|---|---|
QUARRY_PROVIDER |
(auto) | ONNX execution provider: cpu, cuda, or unset (auto-detect) |
QUARRY_API_KEY |
(none) | Bearer token for quarry serve |
QUARRY_ROOT |
~/.punt-labs/quarry/data |
Base directory for all databases |
CHUNK_MAX_CHARS |
1800 |
Max characters per chunk (~450 tokens) |
CHUNK_OVERLAP_CHARS |
200 |
Overlap between consecutive chunks |
For the full configuration reference, see Architecture section 7.
Passive Knowledge Capture
Beyond explicit /ingest and /find commands, quarry runs as a Claude Code plugin with hooks that capture knowledge automatically during your sessions:
| Hook | When it fires | What it does |
|---|---|---|
| Session start | On every session start | Auto-registers your project directory and syncs it in the background. Your codebase is searchable without manual ingestion. |
| Web fetch | After any WebFetch tool call |
URLs Claude fetches during research are auto-ingested into the project's <name>-captures collection (or global web-captures if no project is enabled). |
| Pre-compact | Before context compaction | Captures the conversation transcript into the project's <name>-captures collection (or global session-notes if no project is enabled). |
All hooks are fail-open — failures are ignored and never block Claude Code. Each hook is individually toggleable via .punt-labs/quarry/config.md YAML frontmatter. See AGENTS.md for the full integration model.
How It Works
Quarry runs as a daemon. Claude Code sessions connect through mcp-proxy:
stdio wss:// (TLS)
Claude Code <-----------------> mcp-proxy <---------------------> quarry serve
MCP JSON-RPC (~5 MB Go) pinned CA cert (one daemon)
Without the proxy, every session spawns a separate Python process, each loading the embedding model into ~200 MB of RAM. With it, startup is instant and state is shared across all sessions. All connections use TLS with a self-signed CA — even on localhost.
quarry install downloads mcp-proxy (SHA256-verified, correct platform) and configures MCP clients.
