### Description (declared)

# mcp-win-stdio-tsc

Windows-optimized **Model Context Protocol (MCP)** server for TypeScript diagnostics: persistent background compiler watchers (`tsc --watch`) maintaining an in-memory cache for **0ms latency** error inspection across multi-project and monorepo repositories.

Part of the **`mcp-win-stdio`** Windows-optimized suite.

## 🚀 Features (12 Tools)

- **Dynamic Zero-Env Project Hub**: Track and switch between multiple TypeScript projects dynamically using `list_projects`, `add_project`, and `use_project`. All settings are persisted to `~/.mcp-win-stdio/tsc_projects.json` with zero environment variables required.
- **0ms Diagnostic Cache**: Checks compilation errors instantaneously from memory without spawning slow CLI processes on each turn.
- **Actionable Fix Suggestions (`suggest_error_fixes`)**: Built-in intelligent fix engine for common TypeScript errors (nullish checks, type assertions, missing imports).
- **Categorized Error Breakdown (`get_error_category_breakdown`)**: Groups diagnostics by type, syntax, import/module, and declaration categories.
- **Multi-Project Auto-Discovery**: Automatically scans and watches all `tsconfig.json` configurations across project subdirectories.
- **Token-Safe Error Summaries**: Provides high-level error counts, affected files, and top error codes (e.g. `TS2322`) to avoid flooding Claude's context window.
- **Zero Admin / AppData Crawling**: Quarantines user profile roots (`C:\Users\admin`), `AppData`, and Windows system directories from unintended scans.

## 🛠️ Included Tools (12 Tools)

### Project & Watcher Management
1. `list_projects`: Lists all configured TypeScript workspace projects with live watcher status and active project indicator.
2. `use_project`: Sets the active workspace project for subsequent diagnostic queries.
3. `add_project`: Dynamically registers a TypeScript workspace directory and starts background watchers.
4. `remove_project`: Unregisters a project and stops its compiler watc…
