Repomix MCP Server: Setup for Claude Code, Cursor and Other Apps

• Packs a local folder into one file for the assistant to read

  Bundles a code folder into a single file with a file tree and size metrics, in XML, Markdown, JSON or plain text. You can include or exclude files by pattern and shrink it by keeping only code signatures.

  Try: “Pack /Users/me/projects/shop and tell me which files are largest.”

  Files · pack_codebase

• Downloads a GitHub repo and packs it into one file

  Clones a GitHub repository (owner/repo or a full link, with an optional branch) and packs it the same way. It skips files that look like secrets, though the README calls that scan a best guess.

  Try: “Pack the GitHub repo yamadashy/repomix and explain how it is organized.”

  Network · pack_remote_repository

• Opens a packed file you made before

  Registers an existing Repomix output file, or a folder holding one, so the assistant can read it without packing again. Not available in sandbox mode.

  Try: “Use the repomix-output.xml in my project folder.”

  Files · attach_packed_output

• Reads a packed file, or part of it by line range

  Returns the contents of a packed output by its id. You can ask for a line range so a large file does not flood the chat.

  Try: “Read lines 1 to 200 of that packed output.”

  Read · read_repomix_output

• Searches inside a packed file

  Searches a packed output with a regular expression and shows matching lines with optional lines before and after, like grep.

  Try: “Find every use of fetchUser in the packed output.”

  Read · grep_repomix_output

• Turns a code folder into a Claude skill

  Creates a Claude Agent Skill from a folder: a SKILL.md plus reference files with a summary, the structure and file contents. It is written under .claude/skills inside that project. Not available in sandbox mode.

  Try: “Generate a skill called myapp-reference from /Users/me/projects/myapp.”

  Write · generate_skill

• Reads one file inside the sandbox folder

  Reads a single file. It only exists in sandbox mode, where it cannot reach outside the folder you chose.

  Try: “Read src/index.ts.”

  Files · file_system_read_file

• Lists a folder inside the sandbox folder

  Lists the files and folders in a directory. It only exists in sandbox mode, where it cannot reach outside the folder you chose.

  Try: “List the files in src/.”

  Files · file_system_read_directory

Watch out for

• It can read any folder you can read

  Without the sandbox option, pack_codebase accepts any absolute path your user can open. Use the sandbox option or only point it at project folders. github.com

• A repo's config file can run code

  The README says a repomix config file is code and can run when loaded, so packing a cloned third-party repo is risky. Turn on the sandbox option to skip config files. github.com

• Skill generation writes into your project

  generate_skill creates files under the project's .claude/skills folder. Check the new folder before you commit it. github.com

• Secret filtering is a best guess

  Remote packing skips files that match known secret formats, but the README calls this a heuristic. Do not pack folders that hold keys you cannot share. github.com
