Install

One package, no service:

pip install ratel-ai

The base SDK needs Python 3.10 or newer for the examples in these guides and has no runtime dependencies.

Prebuilt wheels

The SDK bundles Ratel's Rust core as a native module. Prebuilt abi3 wheels ship for:

• macOS: darwin-arm64, darwin-x64
• Linux (glibc): linux-x64-gnu, linux-arm64-gnu
• Windows: win32-x64-msvc

On these targets nothing compiles at install time and no Rust toolchain is needed.

Extras

• mcp: pip install 'ratel-ai[mcp]' pulls the official MCP client for register_mcp_server. Lazily imported: the base SDK installs and runs without it.
• otlp: pip install 'ratel-ai[otlp]' pulls the ratel.* span vocabulary and the OTLP exporter behind configure_telemetry(). See Telemetry & OTel.
• Semantic & hybrid retrieval: not an extra. Opting in downloads the default local embedding model on first use; see The embedding cache and Semantic & hybrid search.
