API Tool Calls
Free small tools for people and AI agents, callable via MCP or HTTP with no sign-up.
API Tool Calls is a collection of browser-based and API-callable utility tools (94–215 tools depending on source) covering images, PDFs, text, QR codes/barcodes, audio/video, and calculators. Tools can be used in the browser with no upload or sign-up, or called programmatically through a single MCP endpoint at https://apitoolcalls.com/mcp with three meta tools (search_tools, get_tool_schema, call_tool) that keep tool definitions under 1k tokens at connection time. Some tools use a shared free daily LLM allowance (Google Gemini) or the caller's own OpenRouter key.
