@rog0x/mcp-file-tools

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.

Tools

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

Tool Details

dir_tree

Generate a visual directory tree like the tree command.

Code

Parameters:
  dir_path (required)     - Absolute path to the directory
  max_depth (optional)    - Max depth to traverse (default: 5, 0 = unlimited)
  ignore_patterns (optional) - Patterns to ignore (default: node_modules, .git, dist, etc.)

file_stats

Get a comprehensive analysis of a directory's contents.

Code

Parameters:
  dir_path (required)     - Absolute path to the directory
  max_depth (optional)    - Max depth to traverse (default: 10)

Returns: total files, total size, file counts by extension, top 10 largest files, top 10 newest/oldest files.

duplicate_finder

Find duplicate files using size pre-filtering and MD5 hashing.

Code

Parameters:
  dir_path (required)     - Absolute path to the directory
  min_size (optional)     - Minimum file size in bytes (default: 1)
  max_depth (optional)    - Max depth to traverse (default: 10)

Returns: duplicate groups with file paths, sizes, and total wasted space.

code_counter

Count lines of code across 20+ languages with comment detection.

Code

Parameters:
  dir_path (required)     - Absolute path to the directory
  max_depth (optional)    - Max depth to traverse (default: 10)

Supported languages: TypeScript, JavaScript, Python, Java, C/C++, C#, Go, Rust, Ruby, PHP, Swift, Kotlin, HTML, CSS, JSON, YAML, Markdown, Shell, SQL, Lua.

file_search

Search for files using multiple criteria simultaneously.

Code

Parameters:
  dir_path (required)        - Absolute path to the directory
  name_pattern (optional)    - Glob pattern (e.g. "**/*.ts")
  content_pattern (optional) - Regex to search file contents
  min_size (optional)        - Minimum file size in bytes
  max_size (optional)        - Maximum file size in bytes
  modified_after (optional)  - ISO date string
  modified_before (optional) - ISO date string
  max_results (optional)     - Max results (default: 100)
