HKUDS/AnyTool

⭐ 703 Python repository created 2025-12-09

AnyTool from HKUDS is a universal tool-use layer that sits between an AI agent and the tools it can call. It targets three problems the authors identify with current agent tooling: contexts that become overwhelming once many tools are registered, community-published tools of uncertain reliability, and coverage limited to whatever a single integration supports. The retrieval path uses a multi-stage progressive filtering pipeline that narrows a large catalogue to the few tools relevant to the current request in milliseconds, so the prompt is not polluted with unused definitions. Embeddings are precomputed and initialisation is lazy, which the project describes as removing redundant work between executions. For scale, adaptive Model Context Protocol tool selection combines caching with selective re-indexing, with the stated aim of holding performance roughly constant from ten tools up to ten thousand as the ecosystem grows. A persistent memory records how tools have behaved, and this reliability tracking feeds a quality-aware selection step alongside execution safeguards, so poor or unsafe tools are avoided over time rather than retried. The backend architecture is multi-modal in the operational sense: beyond web APIs it can drive shell and system operations, GUI automation and deep-research flows through one unified interface, and the shell and GUI backends can run either locally or against a server. Integration is deliberately small: importing AnyTool and using it as an async context manager, then passing a natural-language instruction to execute, runs the whole orchestration, as shown by an example that researches AI coding tools across GitHub and news sources and produces a comparison report. Setup uses a conda environment on Python 3.12 with ffmpeg for video recording, dependencies from requirements.txt, and API keys in a .env file. It runs on macOS, Linux and Windows under the MIT licence.
