The record

Product: LeIndex is a semantic code search engine that searches code by meaning rather than keywords.
Search: It combines TF-IDF lexical matching, Program Dependence Graph structure, and optional local ONNX neural scoring.
Cross-project: It can index and search multiple repositories together.
AI tools: LeIndex runs as an MCP server for AI coding tools, including Claude Code, Cursor, and other MCP-compatible agents.
Integrations: The README provides setup instructions for Zed, Cursor, VS Code, Claude Code, Amp, OpenCode, Qwen CLI, iFlow CLI, Droid, Gemini CLI, and Claude Desktop.
MCP tools: LeIndex lists 20 MCP tools for search, analysis, indexing, reading, editing, renaming, and impact analysis.
Local privacy: The README says local ONNX models keep data on the user's machine and incur no API costs; fragment embeddings are also local unless a remote provider is chosen.
Security: Database discovery is opt-in, sensitive directories such as .ssh, .aws, and .gnupg are automatically excluded, and SQL operations use parameterized queries.
Cloud embeddings: OpenAI, Cohere, and custom OpenAI-compatible embedding endpoints are supported and require network access and provider API keys.
Fallback: Without an embedding backend, LeIndex falls back to offline TF-IDF keyword search, which the README says lacks semantic understanding.
Install paths: The README documents installation through Cargo, npm, PyPI, a release install script, or building from source.
Dashboard: An optional Bun and React dashboard provides project metrics and graph telemetry.
License: The repository states that LeIndex is distributed under the MIT license.
