MCP Server - File Search Tool 🗂️

An MCP (Model Context Protocol) server that provides powerful file system search and inspection capabilities via the MCP protocol. Use this tool to list directories, search file names, read file contents (including PDF and DOCX), and perform regex‑based content searches with context.

Features

• List file paths: Breadth‑first or depth‑first listing, with paging and nested‑level control.

• Search file names: Regex‑based file name search.

• Read files: Read text, PDF, and DOCX files with optional character limits.

• Search file contents: Regex‑based content search with configurable context lines.

• Allowed paths: Restrict server to only browse and search within configured directories.

• Exclude paths: Prevent sensitive directories from being accessed.

• Hide hidden files: Optionally ignore files and directories beginning with a dot.

• Path masking: Replace configured path segments with tokens for privacy.
