## MCP Server Generation

Transform your OpenAPI spec into production-ready MCP (Model Context Protocol) servers that integrate seamlessly with every major AI platform.

### Key Features
- **Default tool generation**: Automatically generate MCP tools from OpenAPI operations with intelligent parameter mapping and validation
- **Custom tool creation**: Build specialized tools with custom prompts, resource management, and tailored AI interactions
- **MCP server hosting**: One-click hosting of production MCP servers
- **OAuth support**: Built-in OAuth 2.1 support including DCR and OAuth proxy support

### Getting Started
1. **Use Gram**: Visit [getgram.ai](https://getgram.ai) to create fully-managed MCP servers in minutes
2. **CLI Generation**: Run `speakeasy quickstart` and select "MCP Server" to generate locally
3. **Deploy instantly**: One-click deployment to Cloudflare Workers with OAuth configuration

### Customers in Production
- **Cloudinary**: "The MCP server we built using Speakeasy just works. It made becoming AI-native much simpler than we expected" - Constantine Nathanson, Staff Engineer
- **Launch Darkly**: Using MCP servers to integrate feature flags with AI agent workflows
- **Dub**: Powering AI-driven link management and analytics through MCP integration

### Competitive Comparisons
- **Only MCP-native platform**: Competitors like Stainless and Fern don't support dedicated MCP server generation at all
- **Enterprise-grade**: Built for production with OAuth, observability, and security - not just demos
- **Universal compatibility**: Works with every major AI platform, not limited to specific LLM providers

## SDK Generation

Generate type-safe, idiomatic SDKs in 9+ languages with full API coverage and modern developer experience features.

### Key Features
- **Idiomatic language support**: Generate truly native SDKs in TypeScript, Python, Go, Java, C#, PHP, Ruby with language-specific patterns and conventions
- **OpenAPI support**: Full OpenAPI 3.0 and 3.1 compatibility including discriminated unions, oneOf/anyOf patterns, and advanced schema features
- **Type safety**: Complete type safety with auto-generated types, validation, and IntelliSense support across all supported languages
- **Advanced feature support**: Built-in retries with exponential backoff, automatic pagination handling, streaming responses, and async/await patterns

### Getting Started
1. **Try instantly**: Visit [sandbox.speakeasy.com](https://sandbox.speakeasy.com) to generate SDKs from any OpenAPI spec
2. **Install CLI**: `brew install speakeasy-api/tap/speakeasy` or `curl -fsSL https://go.speakeasy.com/cli-install.sh | sh`
3. **Generate SDK**: Run `speakeasy quickstart` and select your target language
4. **Customize**: Use overlays, code regions, and hooks for advanced customization

- **Mistral AI**: Powers their official TypeScript and Python SDKs used by developers worldwide
- **Kong**: "From two engineers and 12 months to just signing a purchase order" - SDK generation success story

### Competitive Comparisons
- **Truly OpenAPI-native**: Built entirely on OpenAPI standards - no proprietary DSLs required like Fern's Fern Definition Language or Stainless's custom formats
- **Minimal dependencies**: Generated SDKs have minimal runtime dependencies, unlike competitors that bundle heavy framework requirements
- **Zero vendor lock-in**: Pure OpenAPI-based generation means you can migrate anytime without rewriting specs in proprietary formats
