DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

> 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).

See [SDK Tiering System](/community/sdk-tiers) for details on what each tier means.

## 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.
