mcp-win-stdio

Windows-optimized Model Context Protocol (MCP) suite and interactive CLI hub for local stdio execution with transparent Claude Desktop & Claude Code CLI configuration.

🌟 Highlights

• Interactive Terminal Hub (mws): Run mws alone to view all servers, live installation status ([Installed] vs [Not Installed]), and quick commands.

• Safe, Transparent Setup (mws setup <server>): Installs missing dependencies on-demand, generates exact copy-pasteable JSON configuration for Claude Desktop and Claude Code CLI, and asks confirmation before making any automated edits (always creating .bak backups).

• Excel MCP (20 Tools): High-speed Pandas data queries, multi-column reconciliation with RapidFuzz, cell & formula editing, and native Windows Excel COM automation (PDF exports, recalculation, pivot refreshes, VBA macros).

• Word MCP (10 Tools): Multi-unit page layout geometry (margins in inches, cm, mm, pt), multi-column layout analysis, paragraph spacing/indentation, typography (fonts, sizes, hex colors), and floating/inline header image extraction.

• Workspace Explorer MCP (11 Tools): Token-safe directory exploration, collapsible heavy folders (node_modules, .next, .git), dynamic .gitignore parsing, in-file regex grep, RapidFuzz fuzzy search, and Python/TypeScript AST outline extraction.

• TypeScript Diagnostic Watcher MCP (6 Tools): Persistent background tsc compiler watchers maintaining an in-memory cache for instantaneous (0ms latency) error inspection across multi-tsconfig projects.

• Extensible User Plugins: Drop any standalone Python MCP script into ~/.mcp-win-stdio/plugins/ and it is immediately discovered, runnable, and configurable.

📦 Installation

Install base package (CLI Hub & Discovery Engine):

pip install mcp-win-stdio

Or install with specific optional modules:

# Excel MCP (Pandas + OpenPyXL + RapidFuzz + PyWin32)
pip install "mcp-win-stdio[excel]"

# Word MCP (Python-Docx + PyWin32)
pip install "mcp-win-stdio[word]"

# Explorer MCP (PathSpec + RapidFuzz)
pip install "mcp-win-stdio[explorer]"

# All modules & dependencies
pip install "mcp-win-stdio[all]"

For local development:

git clone https://github.com/indala/mcp-win-stdio.git
cd mcp-win-stdio
pip install -e .

🔌 Custom Plugins from Other PCs

Have custom MCP Python scripts? Simply place your script into:

%USERPROFILE%\.mcp-win-stdio\plugins\my_custom_mcp.py

mcp-win-stdio automatically discovers it:

• View it in mws list

• Run it via mws run my_custom_mcp

• Add it to Claude via mws setup my_custom_mcp
