> Official SDKs for building with Model Context Protocol
Build MCP servers and clients using our official SDKs. SDKs are classified into tiers based on feature completeness, protocol support, and maintenance commitment. Learn more about [SDK tiers](/community/sdk-tiers).

## 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.
