Agent Friendly Apps

Apps and tools that work well with AI agents — have APIs, CLIs, MCP servers, or other programmatic interfaces that let agents interact without screenshots or manual UI automation.

Criteria

• Has an API, CLI, or MCP server

• Can be controlled programmatically

• Works well in headless/automated workflows

• Bonus: built with agent workflows in mind

Manually Added (Apps I Use)

Mac Apps (Agent-Friendly)

• Karabiner-Elements — Low-level key remapping via JSON config (~/.config/karabiner/karabiner.json). Alt to Keyboard Maestro which is GUI-only and NOT agent-friendly

• Espanso — Text expansion via YAML config + CLI (espanso restart). Alt to TextExpander which is GUI-only and NOT agent-friendly

• Hammerspoon — Lua-scripted macOS automation (~/.hammerspoon/init.lua), CLI reload. The most agent-friendly Mac automation tool

• AeroSpace — Tiling window manager, config-file driven. Alt to Rectangle/Magnet (GUI-only)

• OrbStack — Docker/Linux on Mac, full CLI (orb, docker)

• Tailscale — Mesh VPN with CLI (tailscale serve, tailscale status)

• Ghostty — Terminal emulator, config-file based

• 1Password CLI — op command for credential management from terminal

• superwhisper — Voice-to-text with CLI integration

• Peekaboo — macOS native app inspection via MCP server (by steipete)

Semi Agent-Friendly (Has Some Programmability, But Not Full)

These apps have some API/CLI support but still require the GUI for key operations. Notes on what's missing and how they could become fully agent-friendly.

NOT Agent-Friendly — And Their Alternatives

Apps that require GUI interaction for core operations, with agent-friendly replacements.

Directories of Agent-Friendly Sites

Curated Directories & Marketplaces

• Agentic Tools Directory — Curated collection of tools optimized for agent compatibility

• AI Agents Directory — Marketplace and discovery platform for enterprise-ready agents

• AIAgentsList — Community-driven resource for discovering AI agents and compatible tools

• AI Agent Store — Agent marketplace

• Agentic — Marketplace for LLM tools

Search APIs as Agent Gateways

Because many websites block bots, these services provide structured, LLM-ready data:

• Tavily — Search engine built specifically for AI agents and RAG

• Exa — Neural search using embeddings, built for agentic workflows

• Firecrawl — Turns websites into clean Markdown for LLMs

• Jina Reader — Agent-friendly web reading

Emerging Identification Standards

How to tell if a website is agent-friendly:

• llms.txt — Like robots.txt but for LLMs. Markdown summary of site content for AI consumption

• llmstxthub.com — Directory of 4,000+ sites implementing llms.txt

• Model Context Protocol (MCP) — Standard for AI agents to connect to services securely

• MCP Servers Repository — Official + community MCP server implementations

Mac-Specific Agent Tools

• Mac Agent Gateway (MAG) — Local macOS HTTP API exposing system capabilities (Reminders, Messages) as REST

• macOS-use — Agent browser automation for Mac

• BoltAI — Native Mac client with MCP tool integration

• Setapp AI Collection — Curated macOS apps with agent integration

Academic & Research
