serena
A semantic MCP toolkit that turns your coding agent into an IDE.
About serena
serena is a powerful MCP toolkit that gives coding agents semantic retrieval and editing — essentially an IDE for your agent. Instead of blindly grepping and pasting whole files, the agent navigates code by symbols and structure.
It plugs into Claude Code, Codex, and JetBrains via a language server, making edits more precise and token-efficient on large codebases. A strong pick for anyone whose agent struggles once a repo gets big.
