Repomix

Repomix is an MCP server that provides AI assistants with access to the repomix packing tool, transforming local directories or remote Git repositories into structured, AI-friendly files. It connects large language model interfaces, such as Claude Code and Claude Desktop, directly to codebase packaging utilities. Developers and software engineers use Repomix to prepare code context for model evaluations, automated code reviews, architectural analyses, and complex debugging tasks without exceeding context window constraints. The server exposes tools to inspect codebases, calculate token consumption estimates, and compress output into xml, markdown, or plain text formats. Security controls restrict local file system operations strictly to the server launch directory, while temporary output files are automatically removed after content delivery. By enabling upfront size checks through dedicated estimation functions, the server allows AI models to verify payload limits before retrieving packed codebase content, preventing memory overflow and token exhaustion during deep analysis workflows.

How to install and configure Repomix

1. Clone the repository and navigate to the project root directory. 2. Install project dependencies and compile the TypeScript build by running npm install followed by npm run build. 3. For Claude Code, register the server by running: bash claude mcp add --scope user repomix node /path/to/repomix-mcp/dist/index.js 4. For Claude Desktop, edit claude_desktop_config.json to include the server configuration: json { "mcpServers": { "repomix": { "command": "node", "args": ["/path/to/repomix-mcp/dist/index.js"] } } } 5. Restart the MCP client to load the tools.

What you can do with Repomix

• Estimating the token count and file size of a target codebase before packing to ensure it fits context limits. - Packaging local application source directories into XML or Markdown summaries for end-to-end AI code reviews. - Extracting and consolidating remote GitHub repositories using compression flags to analyze third-party libraries. - Filtering specific code modules with inclusion and exclusion globs to isolate bug reproductions for AI debugging.

What can Repomix do?

Repomix packs local code directories or remote Git repositories into a single consolidated file structured for AI consumption. It offers tools to estimate file sizes and token counts, compress outputs to minimize tokens, and format codebases into XML, Markdown, or plain text.

How do I install Repomix?

Run npm install and npm run build inside the cloned repository. Then register the generated dist/index.js file with your client, such as executing claude mcp add for Claude Code or adding the node execution command to your claude_desktop_config.json file.

Which MCP clients work with Repomix?

Repomix works with any MCP-compatible environment, including Claude Desktop and Claude Code. Clients configure it as a local process executed via Node.js pointing to the compiled distribution script.

Is Repomix open source?

Yes, Repomix is open source. The server code and documentation are maintained in a public GitHub repository under the Aeolun user account.

How does Repomix handle file security?

The server restricts local directory reads exclusively to the folder from which it was started, blocking traversal attempts outside that scope. Generated outputs are written to temporary system directories and removed immediately after data transfer.
