- [agent-desktop](https://leyline.ahensya.com/components/agent-desktop.md): Gives agents structured desktop accessibility reads and actions through a CLI, C library and MCP server.
- [VUDA (Visual UI Debug Agent)](https://leyline.ahensya.com/components/vuda-visual-ui-debug-agent.md): An MCP server using Playwright to let AI models visually analyze, automate, test, and debug web interfaces.
- [Agentation](https://leyline.ahensya.com/components/agentation.md): Agentation is a visual feedback layer for agents working on web UIs. Humans click elements, annotate, optionally use layout mode (rearrange/resize), then copy structured markdown (or push via MCP/webhooks) so the agent gets element paths, CSS selectors, positions, and related context instead of vague prose.
- [Sitegeist](https://leyline.ahensya.com/components/sitegeist.md): Sitegeist is an AI assistant that lives in a Chromium side panel, plus a bridge so coding agents can use the same browser. README framing: collaboration over “autonomy theater” — you guide, it executes. Automates repetitive web tasks, extraction, navigation, forms, research → docs/spreadsheets; BYO API key or subscription login (Anthropic, OpenAI/ChatGPT, GitHub Copilot, Gemini, etc.); claims local-only / no tracking.
- [Firecrawl](https://leyline.ahensya.com/components/firecrawl.md): Crawl and extract clean page content for LLM pipelines. A common agent research tool and a Leyline evidence source class.
- [TinyFish](https://leyline.ahensya.com/components/tinyfish.md): Search, fetch, and browser automation for agents. Free Search and Fetch; metered browser runs. Leyline uses it as intake evidence crawl, not as a locked vendor.
- [Grok (xAI)](https://leyline.ahensya.com/components/grok-xai.md): Reasoning and tool-using models plus a CLI harness. Leyline's own intake processor runs on the Grok Heavy subscription.
- [Exa](https://leyline.ahensya.com/components/exa.md): Neural web search API aimed at agents. Search slice with citations, distinct from crawl-the-page tools.
- [Claude Code](https://leyline.ahensya.com/components/claude-code.md): Anthropic's terminal coding agent. Harness grid deep-link target for the Leyline scour skill.
- [Codex](https://leyline.ahensya.com/components/openai-codex.md): OpenAI coding agent / CLI. Another day-one harness on the Leyline install grid.
- [World Monitor](https://leyline.ahensya.com/components/world-monitor.md): Open-source real-time global intelligence / situational-awareness dashboard — AI-synthesized news, multi-layer maps, finance/infra/military/disaster signals, plus first-class agent surfaces (MCP, REST, CLI, SDKs). README one-liner: AI-powered news aggregation, geopolitical monitoring, and infrastructure tracking in a unified situational awareness interface.
- [Cursor](https://leyline.ahensya.com/components/cursor.md): Agentic editor harness. A day-one Leyline install target: scour skill via MCP or rule file.
- [Executor](https://leyline.ahensya.com/components/executor.md): Landing hero: Connect any agent to everything. Tagline: The gateway to connect your agent to everything. Page: Executor is an MCP gateway. Anything that speaks MCP, like Claude Code, Cursor, or Codex, points at one endpoint and reaches every tool you connect.
- [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.
- [ElevenLabs](https://leyline.ahensya.com/components/elevenlabs.md): Developer interfaces for speech generation, transcription, audio and voice-agent workflows.
- [cognee](https://leyline.ahensya.com/components/cognee.md): Open-source memory system for agents and teams. It connects company sources such as Slack, GitHub, and Linear so agents can recall shared context through one memory API, an SDK, or an MCP server, with an optional Cognee Cloud for managed scale.
- [ffmpeg-skill](https://leyline.ahensya.com/components/ffmpeg-skill.md): Local media-editing tools and an agent skill with a machine-readable contract and MCP server.
- [memini](https://leyline.ahensya.com/components/memini.md): Self-hosted persistent memory service for MCP-capable agents. It stores and recalls memories in a tiered store using hybrid vector and keyword retrieval, ships as a single Go binary with SQLite or Postgres, and exposes REST, MCP, and an embedded admin UI.
- [REA](https://leyline.ahensya.com/components/rea.md): README tagline: "One MCP for reverse engineering across binaries, applications, and runtime behavior." The agent calls REA through MCP to inspect a local target and trace relevant code; REA returns findings with their evidence, and the agent uses them to explain the behavior or write and test an implementation.
- [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.
- [Local FAISS MCP Server](https://leyline.ahensya.com/components/local-faiss-mcp-server.md): Local FAISS vector store exposed as an MCP server for document ingestion, embeddings, persistent indexes, semantic search, optional re-ranking, and RAG-style retrieval with MCP prompts.
- [Lore](https://leyline.ahensya.com/components/lore.md): Open-source shared persistent memory for AI agents, backed by Notion. A Lore vault is a Notion page with Projects, Topics, Memories, Entities, and Facts databases so later sessions and people can reuse experiential knowledge, follow-up tasks, decision records, and procedures.
