About BundleDex
The definitive directory of Open Knowledge Format (OKF) bundles — built for agents, by humans.
What is BundleDex?
BundleDex is a curated directory of Open Knowledge Format (OKF) bundles. Think of it as a search engine for AI-ready knowledge — a place where both humans and AI agents can discover, browse, and access structured knowledge packages from across the open web.
As the OKF ecosystem grew, bundles became scattered across thousands of GitHub repositories with no centralized index. AI agents had no standard way to find relevant knowledge bundles. BundleDex solves this by providing a single, agent-friendly entry point to the entire OKF universe.
What is the Open Knowledge Format (OKF)?
The Open Knowledge Format (OKF) is a vendor-neutral, filesystem-based standard for representing knowledge as plain markdown files with YAML frontmatter. Launched by Google Cloud Platform, it is designed to be:
- Authored by humans — write in any text editor, use
catto read - Consumed by AI agents — LLMs can ingest markdown directly, no SDK needed
- Managed in version control — bundles live in git with diffs, PRs, and blame
- Portable and lock-in free — a bundle is just a directory; tar it, ship it, sync it
Each OKF bundle is a directory of markdown documents. Each document (a "concept") has YAML frontmatter for machine-readable metadata and a markdown body for human-readable content. Concepts can cross-link to each other using standard markdown links, forming rich knowledge graphs.
How It Works
For Humans
Browse bundles by category, search by keyword, or explore trending bundles. Each bundle page shows stats, tags, conformance status, and links to the source repository.
For Agents
Discover bundles via the /api/bundles.json endpoint — a complete JSON index consumable by any LLM or agent framework. No auth required.
MCP Protocol
Use our MCP server for real-time, agent-native bundle discovery. Agents can search, filter, and retrieve bundle metadata without leaving their runtime.
Open Submission
Submit your own bundle at bundledex.net/submit. We review within 24 hours. Automated discovery also scans public repositories daily.

Frequently Asked Questions
What is BundleDex?
BundleDex is the definitive directory of Open Knowledge Format (OKF) bundles. It indexes bundles from across GitHub, GitLab, and the open web, making them discoverable by both humans and AI agents. BundleDex provides a searchable web interface, a JSON API, and an MCP server for agent-native discovery.
What is the Open Knowledge Format (OKF)?
Open Knowledge Format (OKF) is a vendor-neutral, filesystem-based standard for packaging knowledge as plain markdown files with YAML frontmatter. Launched by Google Cloud Platform, it is designed to be authored by humans, consumed by AI agents, and managed in version control. OKF bundles are directories of markdown documents that encode concepts, instructions, schemas, and tool definitions.
How do AI agents use BundleDex?
AI agents discover OKF bundles through BundleDex's API at /api/bundles.json, which returns the full indexed bundle list in JSON. Agents can search by tags, download bundles from their source repositories, and load them into context. Tools like Claude Code, Cursor, and OpenCode natively support OKF bundles. BundleDex also provides an MCP server at /mcp for real-time agent-native queries.
How do I get my bundle listed on BundleDex?
Submit your bundle at bundledex.net/submit with its GitHub URL. We review submissions within 24 hours. Your bundle should be publicly accessible and ideally follow the OKF specification. BundleDex also discovers bundles automatically by scanning public repositories daily.
What's the difference between OKF-conformant and non-conformant bundles?
OKF-conformant bundles follow the full specification with proper YAML frontmatter, okf_version field, an index.md entry point, and correctly structured concept documents. Non-conformant bundles use markdown-based knowledge layouts but don't fully adhere to the spec — they're still useful and discoverable, just not portable across all OKF tooling.
Is BundleDex free to use?
Yes. BundleDex is and always will be free and open. The web interface, JSON API, and MCP server are all available at no cost. BundleDex is built for the agent ecosystem, by the agent ecosystem.
How often is BundleDex updated?
BundleDex scans GitHub, GitLab, and the open web daily for new and updated OKF bundles. The bundle index at /api/bundles.json is rebuilt with each scan, ensuring agents always have access to the latest bundles.
Can BundleDex host my bundle content?
No. BundleDex is a directory, not a host. We index bundles and link to their original sources (typically GitHub repositories). We don't store or serve bundle content — this keeps ownership with creators and avoids maintenance burden.
