Serena is the IDE for your coding agent.

• Serena provides essential semantic code retrieval, editing and refactoring tools that are akin to an IDE's capabilities, operating at the symbol level and exploiting relational structure.
• It integrates with any client/LLM via the model context protocol (MCP).

Serena's **agent-first tool design** involves robust high-level abstractions, distinguishing it from approaches that rely on low-level concepts like line numbers or primitive search patterns.

Practically, this means that your agent operates **faster, more efficiently and more reliably**, especially in larger and more complex codebases.

[!IMPORTANT] Don't install Serena via an MCP or plugin marketplace! They contain outdated and suboptimal installation commands. Instead, follow our [Quick Start](#quick-start) instructions.

How Serena Works

Serena provides the necessary [tools](https://oraios.github.io/serena/01-about/035_tools.html) for coding workflows, but an LLM is required to do the actual work, orchestrating tool use.

Serena can extend the functionality of your existing AI client via the **model context protocol (MCP)**. Most modern AI chat clients directly support MCP, including

• terminal-based clients like Claude Code, Codex, OpenCode, or Gemini-CLI,
• IDEs and IDE assistant plugins for VSCode, Cursor and JetBrains IDEs,
• desktop and web clients like Claude Desktop or OpenWebUI.

To connect the Serena MCP server to your client, you either

• provide the client with a launch command that allows it to start the MCP server, or
• start the Serena MCP server yourself in HTTP mode and provide the client with the URL.

See the [Quick Start](#quick-start) section below for information on how to get started.
