SQLite-backed hybrid (vector + FTS) code search index for Claude Code over MCP.
Code Index is an MCP integration. SQLite-backed hybrid (vector + FTS) code search index for Claude Code over MCP.
The published pypi package is mcp-code-index, version 1.0.6. Its declared MCP transport is stdio.
The package declares CODE_INDEX_EMBEDDER: 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: 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: Embedding dimension. Defaults to 768 (matches jina-embeddings-v2-base-code). Must match the model's output dim.; CODE_INDEX_DB: Path to the SQLite index database. Defaults to .claude/index.db relative to the working directory.; CODE_INDEX_EMBED_BATCH: 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: Torch device override: 'cpu', 'mps', or 'cuda'. Unset = auto-detect. Set 'cpu' to avoid Apple-Silicon MPS out-of-memory errors..
Check the maintainer’s instructions for account access, authentication and the supported client configuration. Once connected, inspect the tools your client receives and try a small task that matches the server’s stated purpose. The registry description does not include a verified, complete tool list.
