Tools

This server runs locally, so its tools are listed by your MCP client once it starts.

Environment variables

Name	Description
`CODE_INDEX_EMBEDDER` Optional	Embedder backend. Only 'jina' (local jina-embeddings-v2-base-code via sentence-transformers) is supported; the variable exists for future expansion.
`CODE_INDEX_EMBED_MODEL` Optional	HuggingFace model id. Defaults to 'jinaai/jina-embeddings-v2-base-code'. Override only if you know the model is dim-compatible.
`CODE_INDEX_EMBED_DIM` Optional	Embedding dimension. Defaults to 768 (matches jina-embeddings-v2-base-code). Must match the model's output dim.
`CODE_INDEX_DB` Optional	Path to the SQLite index database. Defaults to .claude/index.db relative to the working directory.
`CODE_INDEX_EMBED_BATCH` Optional	Encode batch size (default 32). Lower (e.g. 8 or 4) to reduce peak memory if the GPU OOMs on large files.
`CODE_INDEX_EMBED_DEVICE` Optional	Torch device override: 'cpu', 'mps', or 'cuda'. Unset = auto-detect. Set 'cpu' to avoid Apple-Silicon MPS out-of-memory errors.
