SWE-smith creates Docker execution environments from GitHub repositories, synthesizes tasks such as file localization and program repair, filters instances that break one or more tests, and generates issue text. The resulting tasks and trajectories can support SWE-agent training or evaluation. It requires Docker and was developed for Ubuntu 22.04; Windows and macOS are not planned targets.

langgraph-bigtool stores tool names, descriptions, namespaces, and other metadata in a LangGraph Store so an agent can search for relevant tools before calling them. It is designed for registries containing hundreds or thousands of tools, supports in-memory and PostgreSQL backends, and lets developers replace the default retrieval logic with a custom function.

MCP-Zero is the open-source code accompanying a paper on active tool discovery and retrieval for autonomous LLM agents. It includes instructions for an MCP-tools dataset covering 308 servers and 2,797 tools, plus code under MCP-tools/build_data for constructing a custom server dataset. The data file must be obtained separately and placed at the path expected by the evaluation code.

ToolRAG registers tools from MCP servers, embeds their descriptions, and uses semantic retrieval to select the functions relevant to a user query. The selected definitions can be passed in an OpenAI-compatible format and executed against the corresponding servers, while LibSQL stores the tool index and embeddings. It is aimed at assistants that need access to many APIs without sending every tool definition on every request.
