๐Ÿง  Embeddings with ONNX Runtime (macOS)

  • Default provider: CPU EP. Works immediately with Homebrew onnxruntime.

  • Optional CoreML EP: Set CODEGRAPH_ONNX_EP=coreml to prefer CoreML when using an ONNX Runtime build that includes CoreML.

  • Fallback: If CoreML EP init fails, CodeGraph logs a warning and falls back to CPU.

How to use ONNX embeddings

# CPU-only (default) export CODEGRAPH_EMBEDDING_PROVIDER=onnx export CODEGRAPH_ONNX_EP=cpu export CODEGRAPH_LOCAL_MODEL=/path/to/onnx-file # CoreML (requires CoreML-enabled ORT build) export CODEGRAPH_EMBEDDING_PROVIDER=onnx export CODEGRAPH_ONNX_EP=coreml export CODEGRAPH_LOCAL_MODEL=/path/to/onnx-file # Install codegraph cargo install --path crates/codegraph-mcp --features "embeddings,codegraph-vector/onnx,faiss"

Notes

  • ONNX Runtime on Apple platforms accelerates via CoreML, not Metal. If you need GPU acceleration on Apple Silicon, use CoreML where supported.

  • Some models/operators may still run on CPU if CoreML doesnโ€™t support them.

Enabling CoreML feature at build time

  • The CoreML registration path is gated by the Cargo feature onnx-coreml in codegraph-vector.

  • Build with: cargo build -p codegraph-vector --features "onnx,onnx-coreml"

  • In a full workspace build, enable it via your consuming crateโ€™s features or by adding: --features codegraph-vector/onnx,codegraph-vector/onnx-coreml.

  • You still need an ONNX Runtime library that was compiled with CoreML support; the feature only enables the registration call in our code.

๐Ÿ“ฆ Prerequisites

System Requirements

  • Operating System: Linux, macOS, or Windows

  • Rust: 1.75 or higher

  • Memory: Minimum 4GB RAM (8GB recommended for large codebases)

  • Disk Space: 1GB for installation + space for indexed data

Required Dependencies

# macOS brew install cmake clang # Ubuntu/Debian sudo apt-get update sudo apt-get install cmake clang libssl-dev pkg-config # Fedora/RHEL sudo dnf install cmake clang openssl-devel

Optional Dependencies

  • FAISS (for vector search acceleration)

    # macOS (required for FAISS feature) brew install faiss # Ubuntu/Debian sudo apt-get install libfaiss-dev # Fedora/RHEL sudo dnf install faiss-devel

  • Local Embeddings (HuggingFace + Candle + ONNX/ORT(coreML) osx-metal/cuda/cpu)

    • Enables on-device embedding generation (no external API calls)

    • Downloads models from HuggingFace Hub on first run and caches them locally

    • Internet access required for the initial model download (or pre-populate cache)

    • Default runs on CPU; advanced GPU backends (CUDA/Metal) require appropriate hardware and drivers

  • CUDA (for GPU-accelerated embeddings)

  • Git (for repository integration)

๐Ÿš€ Performance Benchmarks - pure raw speed!

Run repeatable, end-to-end benchmarks that measure indexing speed (with local embeddings + FAISS), vector search latency, and graph traversal throughput.

For reference indexing this repository with the example configuration yields the following:

2025-09-19T14:27:46.632335Z INFO codegraph_parser::parser: Parsing completed: 361/361 files, 119401 lines in 0.08s (4485.7 files/s, 1483642 lines/s) [00:00:51] [########################################] 14096/14096 Embeddings complete

Apple Macbook Pro M4 Max 128Gb 2025 onnx

Build with performance features

Pick one of the local embedding backends and enable FAISS:

# Option A: ONNX Runtime (CoreML on macOS, CPU otherwise) cargo install --path crates/codegraph-mcp --features "embeddings,codegraph-vector/onnx,faiss" # Option B: Local HF + Candle (CPU/Metal/CUDA) cargo install --path crates/codegraph-mcp --features "embeddings-local,faiss"

Configure local embedding backend

ONNX (CoreML/CPU):

brew install huggingface_hub[cli] hf auth login hf download Qdrant/all-MiniLM-L6-v2 # Check download path # Best to add these to your shell provider config export CODEGRAPH_EMBEDDING_PROVIDER=onnx # macOS: use CoreML export CODEGRAPH_ONNX_EP=coreml # or cpu export CODEGRAPH_LOCAL_MODEL=/path/to/model/(not directly to .onnx)

Local HF + Candle (CPU/Metal/CUDA):

export CODEGRAPH_EMBEDDING_PROVIDER=local # device: cpu | metal | cuda:<id> export CODEGRAPH_LOCAL_MODEL=Qdrant/all-MiniLM-L6-v2

Run the benchmark

# Cold run (cleans .codegraph), warmup queries + timed trials codegraph perf . \ --langs rust,ts,go \ --warmup 3 --trials 20 \ --batch-size 512 --device metal \ --clean --format json

What it measures

  • Indexing: total time to parse -> embed -> build FAISS (global + shards)

  • Embedding throughput: embeddings per second

  • Vector search: latency (avg/p50/p95) across repeated queries

  • Graph traversal: BFS depth=2 micro-benchmark

Sample output (numbers will vary by machine and codebase)

{ "env": { "embedding_provider": "local", "device": "metal", "features": { "faiss": true, "embeddings": true } }, "dataset": { "path": "/repo/large-project", "languages": ["rust","ts","go"], "files": 18234, "lines": 2583190 }, "indexing": { "total_seconds": 186.4, "embeddings": 53421, "throughput_embeddings_per_sec": 286.6 }, "vector_search": { "queries": 100, "latency_ms": { "avg": 18.7, "p50": 12.3, "p95": 32.9 } }, "graph": { "bfs_depth": 2, "visited_nodes": 1000, "elapsed_ms": 41.8 } }

Tips for reproducibility

  • Use --clean for cold start numbers, and run a second time for warm cache numbers.

  • Close background processes that may compete for CPU/GPU.

  • Pin versions: rustc --version, FAISS build, and the embedding model.

  • Record the host: CPU/GPU, RAM, storage, OS version.

๐Ÿ“Š Embedding Provider Options

Ollama (Recommended - Code-Specialized)

export CODEGRAPH_EMBEDDING_PROVIDER=ollama export CODEGRAPH_EMBEDDING_MODEL="hf.co/nomic-ai/nomic-embed-code-GGUF:Q4_K_M" # Benefits: # - Code-specialized understanding (768-dim vectors) # - Superior semantic search relevance # - Local processing, zero external dependencies # - Perfect for your 128GB M4 Max with large batches

ONNX (Alternative - Speed Optimized)

export CODEGRAPH_EMBEDDING_PROVIDER=onnx export CODEGRAPH_LOCAL_MODEL=sentence-transformers/all-MiniLM-L6-v2 # Benefits: # - Faster embedding generation # - Lower memory usage # - Good general-purpose embeddings # - Better for smaller memory systems

Enabling Local Embeddings (Optional)

If you want to use a local embedding model (Hugging Face) instead of remote providers:

  1. Build with the local embeddings feature for crates that use vector search (the API and/or CLI server): ! Recommended to use the onnx version for better performance, see the begginning of the README for installation instructions

# Build API with local embeddings enabled cargo build -p codegraph-api --features codegraph-vector/local-embeddings # (Optional) If your CLI server crate depends on vector features, enable similarly: cargo build -p core-rag-mcp-server --features codegraph-vector/local-embeddings

  1. Set environment variables to switch the provider at runtime:

export CODEGRAPH_EMBEDDING_PROVIDER=local # Optional: choose a specific HF model (must provide onnx model) export CODEGRAPH_LOCAL_MODEL=path/to/Qdrant/all-MiniLM-L6-v2

  1. Run as usual (the first run will download model files from Hugging Face and cache them locally):

cargo run -p codegraph-api --features codegraph-vector/local-embeddings

Model cache locations:

  • Default Hugging Face cache: ~/.cache/huggingface (or $HF_HOME) via hf-hub

  • You can pre-populate this cache to run offline after the first download

### Method 2: Install Pre-built Binary ```bash # Download the latest release curl -L https://github.com/jakedismo/codegraph-cli-mcp/releases/latest/download/codegraph-$(uname -s)-$(uname -m).tar.gz | tar xz # Move to PATH sudo mv codegraph /usr/local/bin/ # Verify installation codegraph --version

Method 3: Using Cargo

# Install directly from crates.io (when published) cargo install codegraph-mcp # Verify installation codegraph --version

๐ŸŽฏ Quick Start

1. Initialize a New Project

๐Ÿ”ง Troubleshooting

Common Issues and Solutions

Issue: Server fails to start

Solution:

# Check if port is already in use lsof -i :3000 # Kill existing process codegraph stop --force # Start with different port codegraph start http --port 3001

Issue: Indexing is slow

Solution:

# Increase workers codegraph index . --workers 16 # Exclude unnecessary files codegraph index . --exclude "**/node_modules/**,**/dist/**" # Use incremental indexing codegraph config set indexing.incremental true

Issue: Out of memory during indexing

Solution:

# Reduce batch size codegraph config set embedding.batch_size 50 # Limit memory usage codegraph config set performance.memory_limit_mb 1024 # Use streaming mode codegraph index . --streaming

Issue: Vector search returns poor results

Solution:

# Adjust similarity threshold codegraph search "query" --threshold 0.5 # Re-index with better embeddings codegraph config set embedding.model openai codegraph index . --force # Use different search type codegraph search "query" --search-type fuzzy #### Issue: Hugging Face model fails to download **Solution:** ```bash # Ensure you have internet access and the model name is correct export CODEGRAPH_LOCAL_MODEL=Qdrant/all-MiniLM-L6-v2 # If the model is private, set a HF token (if required by your environment) export HF_TOKEN=your_hf_access_token # Clear/inspect cache (default): ~/.cache/huggingface ls -lah ~/.cache/huggingface # Note: models must include safetensors weights; PyTorch .bin-only models are not supported by the local loader here

Issue: Local embeddings are slow

Solution:

# Reduce batch size via config or environment (CPU defaults prioritize stability) # Consider using a smaller model (e.g., all-MiniLM-L6-v2) or enabling GPU backends. # For Apple Silicon (Metal) or CUDA, additional wiring can be enabled in config. # Current default uses CPU; contact maintainers to enable device selectors in your environment.

Issue: FAISS linking error during cargo install

Error: ld: library 'faiss_c' not found

Solution:

# On macOS: Install FAISS via Homebrew brew install faiss # Set library paths and retry installation export LIBRARY_PATH="/opt/homebrew/opt/faiss/lib:$LIBRARY_PATH" export LD_LIBRARY_PATH="/opt/homebrew/opt/faiss/lib:$LD_LIBRARY_PATH" # Retry the cargo install command cargo install --path crates/codegraph-mcp --features "embeddings,codegraph-vector/onnx,faiss"

Alternative Solution:

# On Ubuntu/Debian sudo apt-get update sudo apt-get install libfaiss-dev # On Fedora/RHEL sudo dnf install faiss-devel # Then retry cargo install cargo install --path crates/codegraph-mcp --features "embeddings,codegraph-vector/onnx,faiss"

๐Ÿ™ Acknowledgments

Note: CodeGraph runs entirely local-first. These steps build the CLI with all AI/Qwen tooling enabled.

1. Install dependencies

# macOS (Homebrew) brew install faiss # Rust toolchain curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

Ensure faiss libs are visible to the linker (the install script sets sensible defaults):

export LIBRARY_PATH="/opt/homebrew/opt/faiss/lib:$LIBRARY_PATH" export LD_LIBRARY_PATH="/opt/homebrew/opt/faiss/lib:$LD_LIBRARY_PATH" export DYLD_LIBRARY_PATH="/opt/homebrew/opt/faiss/lib:$DYLD_LIBRARY_PATH"

2. Build + install the CLI

Run the bundled installer from the repo root:

bash install-codegraph-osx.sh

This compiles the release binary with the following features:

ai-enhanced, qwen-integration, embeddings, faiss, embeddings-ollama, codegraph-vector/onnx

The binary is copied to ~/.local/bin/codegraph (honoring CODEGRAPH_INSTALL_DIR if you set it). Make sure that directory is on your PATH:

export PATH="$HOME/.local/bin:$PATH"

3. (Optional) Keep a local copy of the release binary

If you prefer to run it from the repo, grab the compiled binary and point CODEGRAPH_BIN at it:

cp target/release/codegraph dist/codegraph export CODEGRAPH_BIN="$(pwd)/dist/codegraph"

4. Verify the MCP tools

export NOTIFY_POLLING=true # avoid macOS FSEvents issues python3 test_mcp_tools.py # exercises all MCP tools

You should see the MCP handshake negotiate protocolVersion: "2025-06-18" and each tool (including code_documentation) return structured JSON.
