Use it to prepare for exams, learn vocabulary, memorize technical terms and facts, improve your material with AI, and review with spaced repetition. The project also includes an external agent API for terminal and AI-agent workflows.\n\n## Available on\n\n- [iOS](https://apps.apple.com/us/app/flashcards-open-source-app/id6760538964)\n- [Android](https://play.google.com/store/apps/details?id=com.flashcardsopensourceapp.app&pcampaignid=web_share)\n- [Web](https://app.flashcards-open-source-app.com/review)\n- MCP server: https://mcp.flashcards-open-source-app.com/mcp\n- Agent API: https://api.flashcards-open-source-app.com/v1/\n\n## Card scheduling\n\nCard scheduling uses FSRS-based spaced repetition. Detailed scheduling rules live in [docs/fsrs-scheduling-logic.md](docs/fsrs-scheduling-logic.md).\n\n## MCP connector\n\nThe hosted MCP server is available at `https://mcp.flashcards-open-source-app.com/mcp` and is listed in MCP registries as `com.flashcards-open-source-app/flashcards`. It exposes three workspace-scoped tools: `list_workspaces`, `sql_query`, and `sql_execute`.\n\nInteractive clients authenticate with OAuth 2.1 authorization code + PKCE and Dynamic Client Registration. Headless clients can use an `fca_` Bearer token.\n\n- [MCP connector docs](https://flashcards-open-source-app.com/docs/mcp-connector/)\n- [Agent API docs](https://flashcards-open-source-app.com/docs/api/)\n- [Privacy](https://flashcards-open-source-app.com/privacy/)\n- [Support](https://flashcards-open-source-app.com/support/)\n\n## Docs\n\n- [iOS app](apps/ios/README.md)\n- [Android app](apps/android/README.md)\n- [Web app](apps/web/README.md)\n- [Architecture](docs/architecture.md)\n- [Backend and web deployment](docs/backend-web-deployment.md)\n- [Public site URLs (`PUBLIC_SITE_BASE_URL`)](docs/public-site-urls.md)\n- [Release gates and monitoring](docs/release-gates.md)\n- [Manual production release](docs/manual-production-release.md)\n- [iOS local setup](docs/ios-local-setup.md)\n- [iOS CI/CD](docs/ios-ci-cd.md)\n- [Android CI/CD](docs/android-ci-cd.md)\n- [Agent API](https://api.flashcards-open-source-app.com/v1/)\n\n## License\n\nThis project is licensed under the MIT License - see the [LICENSE](LICENSE) file for details.\n\n## Author\n\n- [Kirill Markin](https://github.com/kirill-markin)\n",
