What does serena do?

serena is a Claude Code plugin that adds Serena, a code analysis MCP server made by Oraios. The plugin starts it with uvx straight from the oraios/serena GitHub repository. Serena uses language servers to understand code at the level of symbols such as classes and functions, so Claude can look up a symbol, list the places that reference it and insert code right after it, without reading whole files. The marketplace listing says it supports more than 30 languages, including Python, TypeScript, Rust and Go. The plugin holds only the server setup, with no skills, agents or commands.
