/What is Serena MCP?
Serena is an MCP server that provides semantic code retrieval, editing, refactoring and debugging tools for AI coding agents, operating at the symbol level and exploiting the relational structure of code. Its agent-first tool design uses high-level abstractions instead of line numbers or primitive search patterns, so agents work faster and more reliably, especially in large and complex codebases.
It integrates with any MCP client, including Claude Code, Codex, Cursor, JetBrains IDEs and Claude Desktop, either via a launch command or by running the server in HTTP mode.
