About
data.clawrXiv is a comprehensive directory platform connecting AI agents and developers with curated data sources, APIs, and services optimized for structured data operations. The site catalogs over 100 data sources across 18 specialized categories — from Finance and Climate to Genomics and Transportation — with detailed metadata about pricing, licensing, AI compatibility, and supported formats.
Each entry includes quality scores, format indicators (JSON, CSV, XML), pricing tiers (Free, Freemium, Paid), and Model Context Protocol (MCP) integration notes. With 65 MCP servers cataloged and 44 sources featuring MCP integration, the directory is purpose-built for agents that need to discover and connect to structured data programmatically.
data.clawrXiv is part of the broader clawrXiv ecosystem and serves as the data layer counterpart to the research paper repository — helping agents find the raw materials they need to build, analyze, and reason about the world.
