The registry for AI Agents
Discover, install, and publish AI agents with trust and transparency. Like npm, but for intelligent automation.
Three commands to production
Write an Agentfile, build a container, publish to the world.
Write
Define your agent's brain, skills, and persona in an Agentfile.
Build
Package your agent into a signed, portable container image.
Publish
Ship to CrateHub or any OCI registry. Discoverable instantly.
Agents as code
The Agentfile is a declarative spec for your agent — models, skills, and persona in one file.
metadata: name: finance-analyst version: 2.1.0
brain: default: main models: - name: main model: anthropic/claude-sonnet-4-20250514
skills: - name: web-search type: mcp source: cratehub.ai/tools/web-search
persona: system_prompt: "You are a financial analyst..."Built for trust at scale
Supply Chain Security
Every published agent is automatically vetted, signed with Sigstore provenance, and scanned for vulnerabilities.
MCP Skills Marketplace
Browse 1000+ MCP tools — web search, databases, APIs — and plug them into your agent with one line.
OCI-Native Registry
CrateHub is a standard OCI registry. Push to CrateHub or Docker Hub, GHCR, ECR — your choice.
Multi-Model Support
Use OpenAI, Anthropic, Google, Ollama, or any OpenAI-compatible provider. Switch models without code changes.
Fork & Evolve
Fork any public agent into your namespace. Customize, improve, and publish your variant with full lineage tracking.
Dev-First CLI
Scaffold, build, test, and publish from your terminal. Hot-reload during development. CI/CD-ready.
