- [Model Context Protocol](https://leyline.ahensya.com/components/model-context-protocol.md): Open protocol so tools, data, and prompts plug into many harnesses. The connect slice Leyline ranks, not a marketplace.
- [GitHub](https://leyline.ahensya.com/components/github.md): Repo host whose stars, commits, and issues feed Leyline GitHub health — a Score factor, not the whole reputation story.
- [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.
- [CamoFox Browser Server](https://leyline.ahensya.com/components/camofox-browser-server.md): A TypeScript browser-automation server for AI agents that exposes the Camoufox stealth browser engine through REST APIs, a CLI, OpenClaw-compatible endpoints, and stated MCP compatibility.
- [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.
- [Treg](https://leyline.ahensya.com/components/treg.md): Treg is an agent-oriented tool registry and credential-injection proxy. Its hosted catalog claims roughly 2,600 endpoints across about 40 providers, searchable by task with request/response shape and per-call prices. A team can also register its own API credentials, OAuth connections, CLIs, and SKILL.md bundles; callers use one Treg token while upstream credentials remain server-side.
- [Railcode](https://leyline.ahensya.com/components/railcode.md): Railcode is Yakko Majuri’s secure / governed cloud for internal software — apps and agents (“internal Vercel” framing on the launch post). Build with your own tools; deploy into a company-governed sandbox with auth, permissions, data, and connectors centralized.
- [ASP.NET Core](https://leyline.ahensya.com/components/asp-net-core.md): A free, cross-platform, open-source framework for building web apps and services with .NET and C#.
- [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.
- [TinyFish Search API](https://leyline.ahensya.com/components/tinyfish-search-api.md): Web search API that returns structured titles, snippets, URLs, and ranked results for LLM or programmatic use.
- [Vellum Assistant](https://leyline.ahensya.com/components/vellum-assistant.md): Vellum Assistant is a personal AI assistant product (OSS + managed cloud) in the same broad class as Hermes / OpenClaw / NanoClaw: multi-channel agent, skills, memory, computer use, OAuth-connected tools, managed or self-hosted runtime. Entry capture was the OAuth Integrations key-concept doc: browser OAuth2 instead of pasting API keys; each integration is a bundled skill with tools (e.g.
