About This Server
An open-source coding agent toolkit. Provides symbol-level code retrieval and editing via language servers (LSP), giving any agent IDE-grade code understanding as an MCP server.
Installation
uvx --from git+https://github.com/oraios/serena serena start-mcp-serverFrequently Asked Questions
Why does Serena make AI coding more efficient?
It gives AI IDE-grade semantic retrieval and editing: powered by language servers (LSP), it locates and edits code at the symbol level, so whole files never need to be stuffed into context — saving tokens and improving accuracy in large projects.
How do I install Serena?
It needs Python's uv tool: uvx --from git+https://github.com/oraios/serena serena start-mcp-server. In Claude Code, register that command via claude mcp add serena. Dozens of mainstream languages are supported.
Is Serena free? Does it upload my code?
Completely free and open source (MIT), maintained by Oraios AI. All semantic analysis happens in local language servers — your code is never uploaded to any third-party service.
