codexlens-search

Semantic code search engine with MCP server for Claude Code.

Hybrid search: vector + FTS + AST graph + ripgrep regex — with RRF fusion and reranking.

[中文文档](README_zh.md)

Quick Start

pip install codexlens-search[all]

Add to your project `.mcp.json`:

{
  "mcpServers": {
    "codexlens": {
      "command": "uvx",
      "args": ["--from", "codexlens-search[all]", "codexlens-mcp"],
      "env": {
        "CODEXLENS_EMBED_API_URL": "https://api.openai.com/v1",
        "CODEXLENS_EMBED_API_KEY": "${OPENAI_API_KEY}",
        "CODEXLENS_EMBED_API_MODEL": "text-embedding-3-small",
        "CODEXLENS_EMBED_DIM": "1536"
      }
    }
  }
}

That's it. Claude Code will auto-discover the tools: `index_project` -> `Search` -> `locate`.

To enable LLM-enhanced search (`locate`), add LLM API keys:

{
  "mcpServers": {
    "codexlens": {
      "command": "uvx",
      "args": ["--from", "codexlens-search[all]", "codexlens-mcp"],
      "env": {
        "CODEXLENS_EMBED_API_URL": "https://api.openai.com/v1",
        "CODEXLENS_EMBED_API_KEY": "${OPENAI_API_KEY}",
        "CODEXLENS_EMBED_API_MODEL": "text-embedding-3-small",
        "CODEXLENS_EMBED_DIM": "1536",
        "CODEXLENS_LLM_EXPAND_API_KEY": "${GLM_API_KEY}",
        "CODEXLENS_LLM_EXPAND_MODEL": "glm-5-turbo",
        "CODEXLENS_LLM_EXPAND_API_BASE": "https://open.bigmodel.cn/api/paas/v4/"
      }
    }
  }
}
