Overview
Serena transforms a large-language-model into a full-featured autonomous coding agent. It builds rich symbol graphs using Language Server Protocol back-ends, enabling precise code navigation, refactors and multi-step edits even in huge monorepos.
Key Capabilities
- Semantic code search – find functions, classes and references at symbol level across many languages.
- Automated refactoring tools – safely rename, extract methods, reorganize files and update imports.
- Multi-language support – out-of-the-box LSP adapters for Python, TypeScript/JS, Go, Rust, Java, C#, PHP and more.
- Project indexing & caching – incremental indexer maintains fast look-ups and minimizes token usage.
- Flexible integration – works as an MCP server (Claude Code, Cursor, VS Code, JetBrains) or via Agno agent framework.
