Local-first search engine and MCP server for AI agents. One Rust binary indexes code, docs, logs, JSONL/CSV and PDFs for BM25 full-text, vector and hybrid search, code search without grep, agent memory and RAG. Elasticsearch-compatible API; Corpus Hub serves hundreds of reference memory corpora.
XERJ is a local search tool that automatically indexes folders so coding agents can retrieve relevant code, documents, logs, and PDFs without reading files one at a time. It is for developers and agents using code search, retrieval-augmented generation, security audits, or agent memory.
This repository also configures its own agents. See what xerj tells them →
