Google's Agent Development Kit (ADK) is an open-source Python framework that brings software engineering discipline to AI agent development. It takes a code-first approach — developers define agent logic directly in Python, making agents testable, composable, and deployable across different environments without lock-in. ADK supports pre-built tools, custom functions, OpenAPI specs, and MCP integrations. It's designed for multi-agent architectures where specialized sub-agents are orchestrated into scalable hierarchies. A built-in development UI makes local testing and debugging far easier than most competing frameworks, and Cloud Run and Vertex AI deployments are first-class deployment targets. With 19,300+ stars and an Apache 2.0 license, ADK is gaining real traction. While optimized for Google's Gemini models, it's designed to be model-agnostic — an important choice that signals Google understands developers want flexibility, not a guided tour of their cloud bill.

IsItAgentReady is a free web scanner that audits any URL for AI agent readiness across 36 checkpoints organized in five categories: robots.txt compliance (covering all 13 major AI crawler bots), structured data (17 Schema.org types), llms.txt implementation, MCP endpoint detection, and OAuth/agentic commerce readiness. Each category gets a letter grade with specific, actionable fix instructions. The tool was built by a two-person team responding to a growing pain point: as AI agents replace search engine crawlers as the primary way content is discovered and consumed, most websites are not configured to be agent-accessible. A site might have perfect SEO but actively block Claude, GPT, or Perplexity crawlers in its robots.txt — effectively invisible to the AI-driven web. IsItAgentReady surfaces these gaps in about 15 seconds. It also ships as an MCP server, making it usable directly from Claude Code, Cursor, Copilot, or any MCP-compatible environment: run a scan from the terminal and get structured results without leaving your editor. The project is positioned as "Google PageSpeed Insights for the agentic web" — a framing that resonated on Hacker News where it appeared as a Show HN with strong engagement.
Reviewer scorecard
“ADK hits the sweet spot between the simplicity of a prompt wrapper and the complexity of LangChain. The MCP integration and built-in dev UI make it the most productive framework I've tried for real multi-agent systems. The Python-native design means you can test agents like real software.”
“The MCP server integration is the killer feature — I ran it directly from Claude Code on three client sites and had actionable fixes within a minute. The robots.txt check alone is worth the trip: most sites are blocking AI crawlers without realizing it.”
“It's a Google project, which means 'optimized for Gemini' in practice regardless of what the docs promise. The Apache license is great, but you're betting on Google's continued commitment — and Google has an impressive graveyard of abandoned developer tools.”
“The 36 checkpoints sound comprehensive but several are aspirational standards that haven't been widely adopted yet — like MCP endpoint detection and agentic commerce. You risk over-engineering your site for agent features that most users will never use in 2026.”
“ADK represents Google's serious entry into the agent framework wars. The code-first philosophy and MCP-native design suggest they studied what developers actually want. If Gemini and Vertex AI keep improving, this stack will be formidable.”
“This is the 2026 equivalent of Google's mobile-friendly test from 2015. Sites that fail that test eventually lost traffic — sites that fail agent-readiness checks will lose AI-driven discovery. IsItAgentReady is the early warning system before that penalty is enforced.”
“The dev UI for testing agents demystifies what your AI is actually doing — which matters enormously when you're building creative automation. Steep learning curve for non-engineers, but if you have a technical partner, ADK is worth exploring.”
“The graded report with step-by-step fix workflows is genuinely well-designed — it's the kind of output you can hand directly to a developer or a client without translation. Clean, actionable, and free.”
