ByteRover CLI (brv) is a portable memory layer for autonomous coding agents. It enables developers to curate project knowledge into a context tree with git-like version control, sync it to the cloud, and share across tools. The tool provides an interactive REPL powered by choice of LLM, connects to 20+ providers, and offers 24 built-in agent tools for code execution, file operations, and knowledge search. It also supports MCP server integration for broader tool compatibility.
