Graph Tool Call

Graph Tool Call is a Python-based tool that models tool APIs as a graph to enable workflow-aware retrieval and planning for LLM agents. Unlike standard vector search, it returns relevant multi-step tool chains, not just single matches, thereby overcoming context overflow and improving accuracy in scenarios with hundreds or thousands of tools. It enables flexible ingestion (OpenAPI, MCP, Python), history-aware ranking, and integration as a package, CLI, or MCP server for use in AI agent ecosystems and developer workflows.
