Serena turns your AI agent into a symbol-aware coding partner by wrapping LSP language servers or a JetBrains IDE plugin behind MCP tools. Instead of fumbling with line numbers and grep, your agent gets find_symbol, rename_across_files, find_references, and structural refactorings that work at the AST level. It supports 40+ languages through open source language servers or taps into JetBrains' code intelligence if you're running IntelliJ, PyCharm, or WebStorm. The agent-first design means operations like cross-file renames collapse from a dozen fragile edits into one atomic call. Particularly valuable in large codebases where naive text manipulation breaks down and semantic understanding matters.
