universal-plugins-for-ai-agents

Universal plugin catalog for AI agents.

This repository holds portable, production-ready plugin directories that already support multiple agents:

• Claude
• Codex
• Gemini
• OpenCode
• Cursor

slack intentionally remains Claude and Cursor only because Slack's hosted MCP flow is currently documented with client-specific app identity for that path.

Discovery And Marketplace Use

This repository now ships the root discovery artifacts each ecosystem actually supports:

• Claude Code marketplace catalog: .claude-plugin/marketplace.json
• Codex repo marketplace catalog: .agents/plugins/marketplace.json
• Cursor marketplace catalog: .cursor-plugin/marketplace.json
• Gemini bundled root extension: gemini-extension.json

Claude Code can add this repository directly as a marketplace:

/plugin marketplace add 777genius/universal-plugins-for-ai-agents

Then install any listed plugin:

/plugin install context7@universal-plugins-for-ai-agents

Codex reads repo-local marketplaces from .agents/plugins/marketplace.json. Clone this repository, open it as the working repo in Codex, and the marketplace will be available from the local repo catalog.

Cursor now follows the official repo-level marketplace layout used by Cursor plugin repositories and team marketplaces: .cursor-plugin/marketplace.json in the root, plus generated plugins/*/.cursor-plugin/plugin.json manifests for every installable plugin.

Gemini is different. Official Gemini gallery indexing is repository-rooted and expects a public repository with gemini-extension.json at the repository root or archive root plus the gemini-cli-extension GitHub topic. This repository now publishes a bundled root Gemini extension for gallery and scanner visibility, while keeping the authored per-plugin gemini-extension.json files under plugins/*/. The bundled root extension mirrors the 23 Gemini-compatible plugins from this catalog.

OpenCode still relies on the native opencode.json artifacts committed inside each plugin directory.

Marketplace drift is also gated in CI:
