Major Features

MCP Adapter API Refactoring

The MCP adapter has been completely refactored for better type safety and developer experience:

• New Function Signature: Changed from createMcpAdapter(router, options) to createMcpAdapter(options) where router is now a required property in the options object

• Custom Resources: Expose resources that AI agents can read
• OAuth Authorization: First-class support for OAuth-based authorization with automatic Bearer token verification

New Bot Package

Introducing @igniter-js/bot - a comprehensive package for building chatbots with adapters for Telegram and WhatsApp:

• Type-safe bot adapters
• Command handling system
• Message types and middleware support
• Comprehensive documentation and examples

Core Improvements

• Improved Type Inference: Enhanced type inference for server caller with InferServerRouterCaller
• Builder Pattern API: Updated API to use builder pattern consistently
• Request Raw Access: Added request.raw access in controller actions
• Caller Property: Added caller property to router (replacing $caller)
• Procedure Context: Improved procedure context with better type inference

Breaking Changes

MCP Adapter Migration

If you're using the MCP adapter, you'll need to update your code:

// Before (v0.2.x)
const handler = createMcpAdapter(AppRouter, {
  serverInfo: { name: 'My Server', version: '1.0.0' },
  context: (req) => ({
    context: { user: 'test' },
    tools: [],
    request: req,
    timestamp: Date.now()
  })
});

// After (v0.3.x)
const handler = createMcpAdapter({
  router: AppRouter,
  serverInfo: { name: 'My Server', version: '1.0.0' },
  // context is automatically inferred!
});

Caller Property Rename

The $caller property has been renamed to caller:

// Before
const result = await router.$caller({}).action();

// After
const result = await router.caller({}).action();

Middleware Removal

Middlewares have been removed from the Igniter Builder. Use procedures with middleware instead.

• @igniter-js/adapter-mcp-server - MCP Server adapter for AI integrations

Real-Time System

• Type-Safe Events: Type-safe, context-aware event publishing and subscription

• Schema-Based Client: Create schema-based client that eliminates bundle contamination
• Type-Safe Client: Generate type-safe client with zero server code contamination
• Framework Detection: Automatic framework detection and auto-configuration

Turborepo Migration

Migrated repository to Turborepo monorepo structure for better build performance and developer experience.
