- [MCP / AI Gateway](https://leyline.ahensya.com/components/mcp-ai-gateway.md): Gateway layer that routes model calls, discovers MCP tools, and applies identity, policy, and spend controls before invocations.
- [Casdoor](https://leyline.ahensya.com/components/casdoor.md): An open-source, self-hosted identity and access management platform and authentication server with a web console, supporting SSO, multiple identity protocols, policy-based authorization, APIs, SDKs, and MCP.
- [Rikyū](https://leyline.ahensya.com/components/rikyu.md): Rikyū (named for the tea master) is an AI design SaaS: describe what you need in a sentence and it generates a coherent brand/asset set — logo, web, social, print — carried across one visual identity. Positioning: "skip the design work" — no design skills, no asset hunting, one design language across everything that follows.
- [Invisible Playwright MCP](https://leyline.ahensya.com/components/invisible-playwright-mcp.md): A locally run MCP browser agent and optional web UI that automates a stealth Firefox browser for web browsing, scraping, and page interaction.
