About File Merger MCP Server

File Merger MCP Server exposes a simple file-concatenation utility to MCP clients such as Claude Desktop. It merges multiple input files into one output file, works on files of any size, and reports a merge summary including file sizes. Access is sandboxed to the directories you pass as arguments when starting the server, so the model can only read and write inside paths you have approved.

Tools & capabilities (2)

merge_files

Merges multiple files into one. Inputs: inputPaths (string[]) — files to merge; outputPath (string) — output file location. Returns a success message with merge details.

list_allowed_directories

Lists the directories the server is allowed to access.

When to use it

  • Concatenate multiple log or text files into a single combined file
  • Merge split data or document fragments back into one file
  • Combine source or config files for review or processing while keeping access limited to approved directories

Security notes

The server can only access directories explicitly passed as command arguments at launch. Use the list_allowed_directories tool to confirm which paths are accessible.

File Merger MCP Server FAQ

Which directories can the server access?

Only the directories you pass as command-line arguments when launching the server. You can confirm them at any time with the list_allowed_directories tool.
