# AI use cases for Serena (oraios/serena) Repo: [oraios/serena](https://github.com/oraios/serena) | Use cases: 3 | Page: https://dedupedai.com/use-cases/oraios-serena/ Serena is an MCP server that gives coding agents IDE-like tools: semantic code retrieval, symbolic editing, refactoring and debugging that work at the symbol level instead of line numbers and text search. It runs on language servers for over 40 programming languages by default, or on a paid JetBrains plugin for extra refactoring and interactive debugging, and adds a memory system and YAML configuration for long-lived agent workflows. This file holds every use case of this repo. Each one starts with a "## " heading and ends with its URL. - Give your coding agent IDE-level code navigation: https://dedupedai.com/use-cases/oraios-serena/give-your-coding-agent-ide-tools/ - Rename a symbol across a codebase in one call: https://dedupedai.com/use-cases/oraios-serena/rename-symbols-across-files-in-one-call/ - Tune Serena's tools and memory per project: https://dedupedai.com/use-cases/oraios-serena/configure-serena-per-project/ ## How to give your coding agent IDE-level code navigation with Serena Repo: [oraios/serena](https://github.com/oraios/serena) | Difficulty: Beginner | Time: 20 minutes | Basis: From the README Install Serena and connect it over MCP so your agent finds symbols and references instead of grepping files. **Who it is for:** A developer whose Claude Code or Codex sessions burn tokens reading whole files in a big repository. **The problem:** Agents that rely on text search and line numbers waste context and make fragile edits in large codebases. **The outcome:** An agent that uses find symbol, symbol overview and find referencing symbols to explore code at the symbol level. ### Steps 1. Install uv, then run `uv tool install -p 3.13 serena-agent` 2. Check that the Serena command is available, then run Serena init to initialise and verify the setup 3. Do not install Serena from an MCP or plugin marketplace; the README warns those commands are outdated 4. Connect it to your client either with a launch command or by starting Serena in HTTP mode and giving the client the URL 5. Install any extra language server dependencies your languages need from the Language Support page ### Prompt to paste into your agent ```text Install oraios/serena with `uv tool install -p 3.13 serena-agent`, run serena init, and connect it to my as an MCP server. Then use its find symbol and find referencing symbols tools to map how is used across this repo. ``` ### Caveat Serena only supplies tools; the quality of the work still depends on the LLM driving your client.

Set up Serena as an MCP server in your client as in the Quick Start 2. Ask the agent to use Serena's rename tool for the symbol; with language servers it renames symbols only 3. Use replace symbol body, insert after symbol and safe delete for targeted edits 4. For file and directory moves, inline or propagate deletions, use the JetBrains plugin backend 5. Run your tests afterwards with your harness's shell tool ### Prompt to paste into your agent ```text Using oraios/serena's refactoring tools, rename to across this project, then safe delete . List every file that changed and run the tests. ``` ### Caveat Move, inline and propagate deletions are JetBrains plugin only, and that plugin is paid after the free trial.

Install Serena with `uv tool install -p 3.13 serena-agent` 2. Adjust global configuration, then add per-project configuration with local overrides 3. Use execution context-specific configuration for particular clients and modes for composable fragments 4. Leave basic tools such as search_for_pattern and execute_shell_command disabled inside harnesses that already provide them 5. Turn on the memory system, or disable it if you use another, and combine it with your AGENTS.md files ### Prompt to paste into your agent ```text Configure oraios/serena for this repository: per-project configuration with only the retrieval and symbolic editing tools active for , the memory system on, and a short note in AGENTS.md on how agents should use Serena memories. ``` ### Caveat The README describes the configuration levels but the YAML keys are in the docs, so check the configuration page for exact names.
