Context
Agent Papers organizes services that let software agents interact with the outside world, including identity, communications, and payments. Its payment listings separate details such as who holds funds, which payment networks are supported, and what spending controls are documented. Missing information is explicitly marked, helping readers identify questions that still need answers.
The registry is available through both a website and machine-readable interfaces, so developers and agents can consult the same structured information. Its legal-existence category concerns company formation and legal arrangements for operators; it does not establish that an AI system has legal personhood.
- AI agent — An AI system that doesn't just answer once but works toward a goal in a loop — taking actions, reading the results, and deciding what to do next.
- MCP — The Model Context Protocol — an open standard that lets any AI assistant plug into any tool or data source without custom integration code.
- llms.txt — A file at a site's root that gives AI systems a curated, plain-text map of its most useful content — robots.txt's counterpart for comprehension rather than permission.
“Every company giving AI agents what humans have by default: identity, phone numbers, email, addresses, money, legal existence, and insurance.”
“71 companies, every claim checked against sources. Built for agents, readable by humans.”
