pmb vs xerj

pmb: PMB gives Claude Code, Cursor, Codex and other MCP-aware agents a persistent memory kept in one SQLite file on your disk. It offers 29 MCP tools, needs no API keys or subscription, and makes no LLM call on the read path.; xerj: XERJ is a single Rust binary that auto-indexes any folder (code, docs, logs, CSV, PDFs) for BM25, vector and hybrid search behind an Elasticsearch-compatible API. It plugs into Claude Code, Cursor and other MCP clients so agents retrieve exact passages instead of reading files one by one.
