mcp-win-stdio

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

🌟 Highlights (214 Tools Across 9 Modular Servers)

• Interactive CLI 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> / mws add <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).

• Dynamic Guide Merging (mws guide [server]): View comprehensive tool schemas, prompt recipes, and diagnostic checks for individual servers (mws excel-db guide, mws ssh guide, mws git guide, mws db guide) or all installed servers merged (mws guide all).

• Excel MCP (44 Tools): High-speed Pandas data queries, multi-column reconciliation with RapidFuzz, native styled Excel Tables (ListObjects), row/column structural mutations, formula templates, cell merging, workbook diffing, and native Windows Excel COM automation (PDF exports, recalculation, pivot refreshes, VBA macros).

• Git & GitHub MCP (46 Tools): Unified local Git repository management (init, remotes, restore, bookmarks, branching, commits, paginated diffs, conflicts) and remote GitHub CLI (gh) operations (PR checks, releases, issues, Actions) with hybrid synergy workflows.

• Multi-SSH & Remote Management MCP (34 Tools): Advanced multi-host connection pooling, auto-discovery of ~/.ssh/config aliases/identity files/ProxyJump, sticky active host routing, command execution, elevated sudo automation, interactive PTY terminal sessions, detached background jobs, systemd/docker/pm2 service inspection, package listing, log tailing, comprehensive SFTP file management, and background local port forwarding tunnels.

• Polyglot Database MCP (31 Tools): Unified PostgreSQL & MySQL database manager with cross-database switching, cross-schema auto-resolution, fast JSON queries, DBA administrative operations (safety-guarded DROP, CREATE, CLONE), active connection monitoring, index health audits, schema diffing with migration SQL, Mermaid ERD diagrams, row-level data diffing, slow queries, lock blocking trees, CSV/JSON streaming export, and transactional batch CSV import.

• Word MCP (20 Tools): Multi-unit page layout geometry (margins in inches, cm, mm, pt), multi-column layout analysis, paragraph spacing/indentation, typography (fonts, sizes, hex colors), floating/inline header image extraction, document authoring, template placeholder filling, and native Word COM PDF export.

• Workspace Explorer MCP (14 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.

• Excel & DB Power Engine MCP (9 Tools): Zero-context streaming from database to Excel, chunked Excel-to-DB upserting, in-memory cross-source SQL joins, automated reconciliation diffs, multi-master datasets comparison with tolerance, transactional migration generation, and custom Python template pipelines.

• TypeScript Diagnostic Watcher MCP (8 Tools): Persistent background tsc compiler watchers maintaining an in-memory cache for instantaneous (0ms latency) error inspection across multi-tsconfig projects.

• RAG MCP (8 Tools): Multi-collection asynchronous Playwright web crawling, codebase indexing with incremental SHA-256 caching, zero-clone remote GitHub streaming, and hybrid BM25 + dense semantic vector search.

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

📦 Modular Architecture & Installation

Each server is published as an independent, lightweight PyPI package. Installing any standalone package automatically installs the mws CLI orchestrator.

Install Individual Servers:

pip install mcp-win-stdio-excel
pip install mcp-win-stdio-git
pip install mcp-win-stdio-ssh
pip install mcp-win-stdio-db
pip install mcp-win-stdio-word
pip install mcp-win-stdio-explorer
pip install mcp-win-stdio-excel-db
pip install mcp-win-stdio-tsc
pip install mcp-win-stdio-rag

Or Install the Complete Suite:

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 .

   mws guide <server>    -> View complete tool reference & Claude prompts
   mws doctor            -> Run health checks (COM, Python, DB, Git)
   mws run <server>      -> Launch MCP server over stdio
   mws list              -> List all servers and custom plugins
============================================================================

2. Configure a Server for Claude

mws setup git
# or:
mws add db

mws verifies dependencies, generates absolute-path configurations (preventing Windows PATH lookup failures), and optionally writes directly to your Claude Desktop config with automatic backup.

📖 CLI Commands

python -m mcp_win_stdio run git
python -m mcp_win_stdio update all
python -m mcp_win_stdio doctor
