The universal registry for AI agent capabilities
OpenBooklet — one registry
for every AI agent
OpenBooklet is the open registry for AI agent skills, workflows, MCP servers, and collections. Publish once — any agent discovers and uses them instantly. Free, open, verified.
const capabilities = "Everything your agent needs"
Four primitives. One registry. Any agent.
Skills
Single-task instructions — the atomic building blocks of agent behavior. Versioned, verified, and auto-converted to your agent's native format.
skills: - openbooklet.com/s/code-review - openbooklet.com/s/security-audit@^2.0
Workflows
Multi-step skill chains with SHA-256 locked dependencies. One request fetches everything — deterministic, every time.
lint → test → review → deploy
MCP Servers
Pre-configured server definitions agents discover and connect to instantly. 17 tools, 7 resources, zero setup.
npx -y @openbooklet/mcp-server
Collections
Curated sets of skills, workflows, and MCP servers — grouped by topic, team, or use case. Public or private. Subscribe once, stay current.

publish().then(discover)
.then(consume)
From publishing to agent consumption in three steps.
Publish
Create a skill, workflow, or MCP server. We handle validation, versioning, and format conversion automatically.
Discover
Search by keyword or describe what you need in natural language. AI-powered search finds the best match across the entire registry.
Consume
Fetch via URL, API, MCP, CLI, or SDK. Auto-converted to your agent's native format. Cached globally, delivered in under 50ms.
type Registry = Verified & Open & Free
Every capability designed for AI-first consumption with human oversight.
12 Agent Formats
Write once, auto-convert to Claude Code, Cursor, Windsurf, Copilot, GPTs, LangChain, and more.
AI-Powered Discovery
Describe what you need in natural language. Semantic search finds the best match — not just keywords.
Workflow Engine
Chain skills into multi-step pipelines. Dependencies are locked and delivered as a single bundle.
MCP Servers
Pre-configured server definitions agents can discover and connect to. Extend capabilities across the registry.
Verified Ownership
Every asset is content-hashed and timestamped at publish. Permanent, tamper-proof authorship proof.
Safety First
Automated safety scanning catches prompt injection, data exfiltration, and malicious patterns before publishing.
Global Edge Delivery
330+ edge locations worldwide. Sub-50ms response times. Smart caching with ETag validation.
Semantic Versioning
Pin versions, auto-update within ranges, view changelogs, and roll back from the dashboard. Dependencies are SHA-256 locked.
const { workflows, collections } = registry
Workflows for multi-step automation. Collections for curated grouping.
Workflows
Multi-step skill chains with locked dependencies. One request fetches everything — deterministic, every time.
Collections
Personal or team-curated sets. Mix skills, workflows, and MCP servers. Public or private — your choice.
await registry.publish(skill)
Publish once, reach every AI agent on Earth. Your reputation grows with every pull.
Verified trust tiers
Progress from New → Rising Star → Pro → Master as your contributions earn recognition across the ecosystem.
Real-time analytics
Pull counts, agent compatibility scores, and rating distributions. Always know exactly who's using your work.
Global leaderboard
Top publishers surface organically. Get discovered by agents and developers building the next generation of AI.
import { URL, API, MCP, CLI, SDK } from "@openbooklet"
Six ways to integrate. From zero-config URL fetching to deep MCP tooling. All open, all documented.
Direct URL
Any agent that can fetch a URL — zero setup.
# In your CLAUDE.md or agent config skills: - openbooklet.com/s/code-review - openbooklet.com/s/security-audit@^2.0
REST API
70+ endpoints for search, fetch, publish, and analytics.
curl https://openbooklet.com/api/v1/skills/code-review-pro \ -H "Authorization: Bearer ob_live_..."
MCP Server
17 tools + 7 resources for native AI agent integration.

TypeScript SDK
Zero-dependency client library.
import { OpenBooklet } from "@openbooklet/sdk";
const ob = new OpenBooklet({ apiKey: "ob_live_..." });
const results = await ob.search("security audit");GitHub Import
Import skills from any public repo or raw URL.
# Import from a raw URL $ ob import https://raw.githubusercontent.com/ you/repo/main/SKILL.md # Or scan a repo for SKILL.md files $ ob import github.com/you/your-repo
