opencli

OpenCLI turns any website, Electron app, or local binary into a CLI command your AI agent can call. Think of it as a universal adapter — 50+ sites (Reddit, HackerNews, Bilibili) already have adapters, and it auto-discovers APIs for new ones. Your agent runs "opencli list" and instantly knows every tool available.

If you're building agent workflows that need to interact with the web — scraping, posting, automating — OpenCLI is a shortcut past writing custom integrations. It reuses your Chrome's logged-in state, so credentials never leave the browser. The dual-engine architecture (YAML declarative + TypeScript injection) covers both simple scraping and complex interactions.

Alternatives: Puppeteer/Playwright give you more control but need custom code per site. Browser-use is AI-native but heavier. MCP servers are the Claude-native approach but require per-service setup.

The catch: the AGENT.md integration is clever but couples you to a specific agent paradigm. Coverage outside the built-in 50 sites requires writing your own adapters. And scraping-based approaches are inherently fragile — one site redesign breaks your workflow.
