io.github.rog0x/file is an MCP server that dir tree, file stats, duplicates, LOC for AI agents. Its tool list has not been published yet over stdio and http, requires no API key, and scores 48/100 on MCPpedia's security, maintenance and efficiency rubric.
Config is the same across clients - only the file and path differ.

Packing does not respect root-level ignore files in workspaces
### Impact `npm pack` ignores root-level `.gitignore` & `.npmignore` file exclusion directives when run in a workspace or with a workspace flag (ie. `--workspaces`, `--workspace=<name>`). Anyone who has run `npm pack` or `npm publish` with workspaces, as of [v7.9.0](https://github.com/npm/cli/releases/tag/v7.9.0) & [v7.13.0](https://github.com/npm/cli/releases/tag/v7.13.0) respectively, may be affected and have published files into the npm registry they did not intend to include. ### Patch - Up
Incorrect Permission Assignment for Critical Resource in NPM
An issue was discovered in an npm 5.7.0 2018-02-21 pre-release (marked as "next: 5.7.0" and therefore automatically installed by an "npm upgrade -g npm" command, and also announced in the vendor's blog without mention of pre-release status). It might allow local users to bypass intended filesystem access restrictions because ownerships of /etc and /usr directories are being changed unexpectedly, related to a "correctMkdir" issue.
Local Privilege Escalation in npm
Affected versions of `npm` use predictable temporary file names during archive unpacking. If an attacker can create a symbolic link at the location of one of these temporary file names, the attacker can arbitrarily write to any file that the user which owns the `npm` process has permission to write to, potentially resulting in local privilege escalation. ## Recommendation Update to version 1.3.3 or later.
npm CLI exposing sensitive information through logs
Versions of the npm CLI prior to 6.14.6 are vulnerable to an information exposure vulnerability through log files. The CLI supports URLs like `<protocol>://[<user>[:<password>]@]<hostname>[:<port>][:][/]<path>`. The password value is not redacted and is printed to stdout and also to any generated log files.
npm Vulnerable to Global node_modules Binary Overwrite
Versions of the npm CLI prior to 6.13.4 are vulnerable to a Global node_modules Binary Overwrite. It fails to prevent existing globally-installed binaries to be overwritten by other package installations. For example, if a package was installed globally and created a `serve` binary, any subsequent installs of packages that also create a `serve` binary would overwrite the first binary. This will not overwrite system binaries but only binaries put into the global node_modules directory. This b

MCP server providing file and directory analysis tools for AI agents. Gives Claude (and other MCP-compatible AI) the ability to explore, analyze, and search file systems.
| Tool | Description |
|---|---|
dir_tree | Generate a visual directory tree structure with configurable depth and ignore patterns |
file_stats | Analyze a directory: total files, size breakdown by extension, largest/newest/oldest files |
duplicate_finder | Find duplicate files by size + MD5 hash, report wasted space |
code_counter | Count lines of code by language: code, comments, and blank lines (like cloc/scc) |
file_search | Search files by name glob, content regex, size range, and date range |
git clone https://github.com/rog0x/mcp-file-tools.git
cd mcp-file-tools
npm install
npm run build
claude mcp add mcp-file-tools node /absolute/path/to/mcp-file-tools/dist/index.js
Add to your claude_desktop_config.json:
{
"mcpServers": {
"mcp-file-tools": {
"command": "node",
"args": ["/absolute/path/to/mcp-file-tools/dist/index.js"]
}
}
}
Generate a visual directory tree like the tree command.
Parameters:
dir_path (required) - Absolute path to the directory
max_depth (optional) - Max depth to traverse (default: 5, 0 = unlimited)
