Asta Agents/MCP

Asta Agents (Ai2) is an open-source AI research assistant ecosystem: it uses the Model Context Protocol (MCP) to access and synthesize evidence from a 200M+ scientific corpus.

Asta Agents, developed by the Allen Institute for AI (Ai2), is a robust, open-source AI research assistant designed to accelerate scientific discovery. It acts as a transparent, source-cited collaborator, executing complex, multi-step tasks like literature review, evidence synthesis, and data analysis (in beta). The core functionality leverages the Model Context Protocol (MCP) to provide agents with standardized, real-time access to external resources; this includes the Scientific Corpus Tool, an MCP extension of the Semantic Scholar API that indexes over 200 million papers. The full Asta ecosystem also features AstaBench (a rigorous benchmarking suite with 11 benchmarks) and Asta Resources (a developer toolkit), ensuring trustworthy and verifiable scientific AI performance.
