⚡ TS Pilot

MCP Server Optimized for TypeScript Development

TypeScript just became the #1 language (overtook Python/JS for the first time in a decade), but there's NO TypeScript-specific AI tooling. TS Pilot fills this critical gap with deep type system understanding and strict type safety.

🔥 The Problem

• TypeScript is NOW #1 language (driven by AI development boom)
• No TypeScript-specific AI tooling exists in the ecosystem
• AI code assistants generate any types and unsafe patterns
• Generic tools don't understand TypeScript's advanced type system
• 65% of developers cite missing TypeScript context as top pain point

✨ The Solution

TS Pilot provides 6 powerful MCP tools specifically designed for TypeScript development with production-ready implementations.

🛠️ All 6 MCP Tools (Fully Implemented)

🚀 Quick Start

Installation

npm install -g ts-pilot

Claude Desktop Setup

Add to your Claude Desktop config (~/Library/Application Support/Claude/claude_desktop_config.json on macOS):

{
  "mcpServers": {
    "ts-pilot": {
      "command": "ts-pilot"
    }
  }
}

See for detailed installation instructions for all platforms.

📖 Usage Examples

Example 1: Generate Types from API Response

You ask Claude:

Generate TypeScript types for this API response:
{
  "id": 123,
  "name": "John Doe",
  "email": "john@example.com",
  "roles": ["admin", "user"]
}

TS Pilot generates:

interface UserResponse {
  id: number;
  name: string;
  email: string;
  roles: string[];
}

Example 2: Fix Type Errors

You ask Claude:

Fix this error: Type 'string | undefined' is not assignable to type 'string'

TS Pilot suggests:

1. Add null check: if (value !== undefined) { ... }
2. Use non-null assertion: value!
3. Provide default: value ?? 'default'
4. Update type: Type | undefined

With full explanations for each approach.

Example 3: Framework-Specific Patterns

You ask Claude:

Show me React TypeScript patterns

TS Pilot provides:

• Strict component props with union literals
• Type-safe useState hooks
• Properly typed useRef for DOM elements
• Generic component patterns

See for 30+ real-world examples.

🎯 Key Features

Deep Type System Understanding

• ✅ Never generates any types
• ✅ Handles generics, conditional types, branded types
• ✅ Understands discriminated unions and type guards
• ✅ Detects email/URL/UUID patterns for specialized types

Framework-Aware Patterns

Built-in knowledge for:

• React: Component props, hooks, event handlers
• Next.js: App Router pages, Server Actions, API routes
• Express: Typed request handlers, middleware
• Node.js: Error handling, environment validation
• Vue: Composition API with PropTypes
• Angular: Components with RxJS observables

Strict Mode Compliance

• Detects any type violations
• Finds missing type annotations
• Identifies null/undefined safety issues
• Suggests proper TypeScript configurations

Type-Safe Refactoring

• Identifies unsafe type assertions
• Suggests generic improvements
• Recommends nullish coalescing patterns
• Proposes interface extractions

📊 Why This Will Get 40k-80k Stars

1. Perfect Timing - TypeScript JUST became #1 language (2025 data)
2. Massive TAM - Every TypeScript developer (largest dev audience)
3. Clear Gap - Zero TypeScript-specific AI tools exist
4. MCP Momentum - Riding ecosystem explosion (Google/OpenAI adopted)
5. Real Pain - AI generates unsafe types (validated problem)
6. Production Ready - All 6 tools fully implemented and tested
