Lancer

概要

Lancer MCP is a self-hosted Model Context Protocol (MCP) server designed to empower AI agents with advanced code intelligence. It efficiently clones and tracks Git repositories, performing incremental indexing, multi-language code parsing, and embedding generation. By combining BM25 full-text search, vector semantic search, and graph re-ranking, Lancer delivers highly relevant search results. Its unique approach utilizes a single, unified `Query` MCP tool to optimize performance and accuracy for LLMs, offering a private, powerful, and extensible alternative to cloud-based code indexing services.
