OpenTools

OpenTools is a unified API that lets you connect any LLM to a growing ecosystem of Model Context Protocol (MCP) tools with a single line of code. Instead of wiring up individual integrations, you reference the tool by name in your request—like `google-maps`—and OpenTools handles the execution automatically. It's built for developers building agentic workflows that need real-world data: web search, location lookups, web scraping, and more, all through an OpenAI-compatible completions endpoint. The platform is model-agnostic, meaning you can switch between LLMs (e.g., Google Gemini) without changing your code. This also gives you resilience against provider outages—if one model goes down, you can route to another. The API is backwards compatible with traditional function calling, so teams with existing function-calling logic can migrate with minimal friction. Pricing is transparent: you only pay for tool execution, and tokens are passed through at cost. All usage is billed in one unified portal, eliminating the hassle of managing multiple LLM and external service accounts. No personal API keys are needed for tool access, which simplifies setup and reduces security overhead. For teams evaluating tool-use platforms, OpenTools offers a lightweight alternative to heavier integration layers like Composio or Zapier's AI agents, especially if you want to stay MCP-native and avoid vendor lock-in. The recent launch of OpenPrinter—an open-source project that gained traction on Hacker News—shows the team is actively contributing to the broader ecosystem.
