When pip has no prebuilt pymgclient wheel for your platform it builds from source, and the build can fail first on a missing CMake and then on OpenSSL headers CMake cannot locate (Homebrew does not put OpenSSL on the default search paths). Install the build dependencies and point CMake at Homebrew's OpenSSL:

brew install cmake pkg-config openssl
export OPENSSL_ROOT_DIR="$(brew --prefix openssl)"
export PKG_CONFIG_PATH="$(brew --prefix openssl)/lib/pkgconfig:$PKG_CONFIG_PATH"

Then rerun the install in the same shell. Verified recipe: with those variables set, pip install --no-binary pymgclient pymgclient builds and imports cleanly.

• Ensure Docker containers are running: cd ~/.cgr && docker compose ps (the compose file cgr daemon up writes lives there), or cgr daemon status
• Verify Memgraph is accessible on port 7687

• Open http://localhost:3000
• Connect to memgraph:7687

• Verify Ollama is running: ollama list
• Check if models are downloaded: ollama pull qwen2.5-coder
• Test Ollama API: curl http://localhost:11434/v1/models
• Check Ollama logs: ollama logs

1. Check the logs for error details
2. Verify Memgraph connection
3. Ensure all environment variables are set
4. Review the graph schema matches your expectations
5. Run cgr doctor to validate your setup

Grammar not found: Use a custom URL:

uv run cgr language add-grammar --grammar-url https://github.com/custom/tree-sitter-mylang

"modifies a code-graph-rag source checkout": add-grammar and remove-language edit a clone of this repository, not your project. Run them with uv run cgr inside a clone, or request the language.

Version incompatibility: Update tree-sitter:

uv add tree-sitter@latest

Missing node types: Manually adjust the configuration in codebase_rag/language_spec.py.
