Serena is a symbol-aware coding agent toolkit that uses the Language Server Protocol (LSP) to provide deep semantic understanding of codebases within Claude Code.

How do I use Serena in Claude Code?

Serena can be used via direct MCP tools like find_symbol or through CLI commands using the execute_command tool with uvx.

Which languages does Serena support?

It supports over 30 languages out-of-the-box, including Python, TypeScript, JavaScript, Rust, Go, Java, C++, and many more via standard LSP servers.

How does Serena differ from ripgrep?

Unlike ripgrep's text-based search, Serena understands code semantics, allowing it to distinguish between a function definition, an import, and a call site.

Can Serena help with refactoring tasks?

Yes, it provides tools to track every reference of a symbol across your project, enabling safe renames, method insertions, and surgical code replacements.

Provides deep code understanding and precise semantic navigation using Language Server Protocol (LSP) for over 30 programming languages.

关于

Serena transforms Claude into a symbol-aware coding agent, moving beyond simple text searches to understand the true semantic structure of your codebase. By leveraging Language Server Protocol (LSP) integration, it provides IDE-like capabilities such as locating symbol definitions, tracking all cross-file references, and performing surgical code insertions. This skill is indispensable for complex refactoring, impact analysis, and navigating large, multi-file projects where structural understanding is more critical than pattern matching.
