mcp-win-stdio

Windows-optimized Model Context Protocol (MCP) suite and non-invasive CLI hub (mws) for local stdio execution across all major AI IDEs, CLI agents, and desktop apps (Gemini, Antigravity, Claude, ChatGPT, Cursor, Kiro, OpenCode, Windsurf, Copilot, Codex).

🌟 Highlights (230+ Tools Across 10 Modular Servers)

• Unified On-Demand Gateway & Workflow Engine (mws server): Configure just mws server (or python -m mcp_win_stdio.server) in Claude Desktop, Cursor, Gemini, or Antigravity. Instead of dumping 200+ tools (35,000+ tokens) into the context window, it exposes 10 lightweight meta-tools (~500 tokens) that lazily spawn child servers and execute agent-synthesized multi-step workflows in 0 LLM turns!

• Agent-Synthesized Workflows (.mws/workflows/): AI agents and developers can chain multiple MCP tools into named composite pipelines with argument templating and error halting.

• 100% Dynamic & Zero-Env Architecture: All configurations (databases, TypeScript projects, SSH hosts, Git repositories) are managed interactively and stored in ~/.mcp-win-stdio/. No environment variables required in client configs!

• Universal Multi-Agent Guide (mws guide): Generates tailored copy-paste configuration snippets and exact configuration file paths for 10 major AI agents without mutating user files.

• Cascading Clean Uninstallation (mws uninstall self): Dynamically discovers and purges all installed mcp-win-stdio-* distributions in one atomic batch.

• Excel MCP (44 Tools): High-speed Pandas queries, multi-column reconciliation with RapidFuzz, native Excel Tables, row/col mutations, formulas, cell merging, workbook diffing, and Office COM automation.

• Git & GitHub MCP (46 Tools): Unified local Git management (init, remotes, restore, bookmarks, branches, commits, diffs) and remote GitHub CLI (gh) operations (PR checks, releases, issues, Actions).

• Multi-SSH MCP (34 Tools): Multi-host connection pooling, auto-discovery of ~/.ssh/config, interactive PTY terminal sessions, detached background jobs, systemd/docker services, SFTP file management, and port forwarding.

• Polyglot Database MCP (34 Tools): PostgreSQL & MySQL manager with dynamic connection hub, cross-schema resolution, index health audits, schema diffing with migration SQL, Mermaid ERD, slow queries, lock trees, and streaming export/import.

• Word MCP (20 Tools): Multi-unit geometry (in, cm, mm, pt), multi-column layout, typography, document authoring, template placeholder filling, and native Word COM PDF export.

• Workspace Explorer MCP (14 Tools): Token-safe directory exploration, collapsible heavy folders, .gitignore resolution, in-file regex grep, RapidFuzz fuzzy search, and Python/TypeScript AST outlines.

• Excel & DB Power Engine MCP (9 Tools): Zero-context streaming from database to Excel, chunked upserting, in-memory cross-source SQL joins, automated reconciliation diffs, and migration planning.

• TypeScript Diagnostic Watcher MCP (12 Tools): Persistent background tsc compiler watchers maintaining an in-memory cache for instantaneous (0ms latency) error inspection and actionable fixes.

• RAG MCP (10 Tools): Multi-collection web crawling, incremental local and remote repository indexing, hybrid BM25 + TF-IDF search, and knowledge trees.

• Architecture Knowledge Graph MCP (5 Tools): Full-stack vertical blueprint flowcharts, execution trace down to storage entities, ERD diagrams, and blast-radius impact analysis.

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

📦 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
pip install mcp-win-stdio-arch

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 .

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

mws follows a zero-mutation, non-invasive philosophy: it never automatically modifies your agent's configuration files. Use mws guide to inspect copy-paste configuration snippets and exact file paths for your AI client.
