Currently no self-serve marketplace submission. Plugins are distributed via local marketplaces (~/.agents/plugins/marketplace.json), repo marketplaces ($REPO_ROOT/.agents/plugins/marketplace.json), or GitHub repos by pointing a marketplace source at a repo. OpenAI has stated third-party marketplace submissions are coming soon.
Before submitting a plugin, run the codex-plugin-scanner to check for security issues and best practices. It scores your plugin from 0-100 and generates actionable findings.

Every plugin in this list is automatically ingested by the HOL Plugin Registry, which runs each through the codex-plugin-scanner to produce a trust score and security analysis.
Each plugin gets a detailed breakdown across six factors:
- Installability - Can the plugin be installed and run without errors?
- Maintenance - Is the repo actively maintained with clear documentation?
- MCP Posture - How securely are MCP servers configured?
- Plugin Security - Does the manifest follow security best practices?
- Provenance - Can the publisher's identity be verified?
- Publisher Quality - Does the publisher have a track record of quality releases?
You can embed a trust badge in your plugin's README:
[](https://hol.org/registry/plugins/OWNER%2FREPO)
Replace OWNER%2FREPO with your plugin's GitHub owner and repo name (URL-encoded slash). Metrics available: trust, security. Styles: flat, flat-square, plastic, for-the-badge, social.
