Free
What is Serena?
Serena is an open-source MCP toolkit from Oraios AI that gives coding agents IDE-like abilities, finding and editing code by symbols such as functions and classes instead of reading whole files.
Serena uses language servers to understand code structure across more than 40 languages, including Python, JavaScript, TypeScript, Java, Go, Rust and C and C++. It works as an MCP server with Claude Code, Codex, Claude Desktop, Cursor, JetBrains IDEs and VS Code. The Serena application is GPL-3.0-or-later and the SolidLSP component MIT; a paid JetBrains plugin with a free trial offers an alternative back end. Oraios AI lists Germany as its location on GitHub. The GitHub API showed about 29,900 stars and a push on September 24, 2026.
Serena AI features and use cases
- Finds code by meaning of symbolsAgents look up a function, its references and callers instead of scanning files. They need less context, which lowers token costs and helps in large code bases.
- Refactors across filesSymbol-level editing supports cross-file renames and structured changes. Agents make fewer broken edits when changing shared code.
- Adds IDE knowledge to any agentBecause it is an MCP server, the same capabilities work in several coding assistants. Teams can keep their preferred agent and still get language-server precision.
What sets Serena apart
- Works at the level of code symbols through language servers, covering more than 40 languages.
- Maintained by Oraios AI in Germany, with an optional paid JetBrains back end.

Questions to ask before you buy Serena
Serena runs locally with access to your code base and can edit files, so use it with version control and review changes. The GPL-3.0 license matters if you plan to distribute modified versions. Code snippets still go to the model provider of your coding agent.
