Getting Started
Each SDK provides the same functionality but follows the idioms and best practices of its language. All SDKs support:
- Creating MCP servers that expose tools, resources, and prompts
- Building MCP clients that can connect to any MCP server
- Local and remote transport protocols
- Protocol compliance with type safety
Visit the SDK page for your chosen language to find installation instructions, documentation, and examples.
