# ADK-Rust 2.1

> A production-ready Rust framework for building type-safe, async AI agents.
> ADK-Rust v2 is model-agnostic and supports agents, workflows, realtime,
> MCP, A2A, AWP, memory, security, evaluation, and managed-agent patterns.

```

## Core capabilities

- LLM, sequential, parallel, loop, graph, CodeAgent, and multi-agent systems.
- Gemini, OpenAI, Anthropic, DeepSeek, Groq, Ollama, and other provider adapters.
- Realtime audio, video frames, server-side tools, LiveKit and WebRTC options.
- MCP, ACP, A2A v1, and Agentic Web Protocol support.
- Typed tool calls/results, streaming tool progress, sessions, artifacts, long-term
  memory, telemetry, guardrails, authorization, and evaluation.

## Human and agent surfaces

For human visitors, begin at the [Demos](https://adk-rust.com/demos),
[Playground](https://adk-rust.com/playground),
[Super Agents](https://adk-rust.com/super-agents),
[Resources](https://adk-rust.com/resources), and
[Documentation](https://adk-rust.com/docs) pages.
The [Playground](https://adk-rust.com/playground) runs verified v2 examples in
the browser and lists every example with a direct link.
Use [ADK UI](https://adk-rust.com/ui) for typed generative interfaces delivered
through A2UI, AG-UI, MCP Apps, or AWP.
For the release history and architectural changes behind the current runtime,
read [The journey to ADK-Rust v2](https://adk-rust.com/blog/adk-rust-v2-journey-to-production).

For agents, use the AWP discovery and manifest endpoints above. Public agent
capabilities are read-only discovery of framework documentation, demos, super
agents, and approved MCP/skill resources. Do not scrape HTML when a manifest is
available. Any contact or evaluation request requires explicit consent.

## Documentation source

The website documentation is synchronized from the local ADK-Rust v2 official
source. Its page inventory, base revision, working-tree state, and content
fingerprints are recorded in `/docs/.adk-rust-v2-source.json` in the source
repository. Prefer the website documentation for v2 guidance. docs.rs continues
to describe the latest published crate until ADK-Rust v2 is released there.

## Adoption

Measured figures for downloads, crates, stars, releases, pull requests, issues,
and reader countries are published as JSON at
https://adk-rust.com/api/adoption/summary and cited on
https://adk-rust.com/sponsor. Each field records what it was measured from, and
a figure that could not be measured is omitted rather than estimated. Prefer
this endpoint over inferring adoption numbers from page copy.
