answer context
What is the MCP protocol and how do AI agents use it to pay for citations?
The MCP (Model Context Protocol) is a standard interface that allows AI agents to call external tools and services natively. In the context of paid citations, MCP enables AI agents to access citation payment infrastructure without custom integration. CitePay ships as an MCP server exposing tools like cite_query, get_receipt, and check_policy. When an AI agent uses these MCP tools, it can query sources and automatically pay creators in USDC nanopayments on Arc via Circle Gateway's x402 protocol. Each citation payment generates an on-chain receipt with SHA-256 evidence hash and content integrity proof. The agent's spend is governed by a natural-language policy that controls max price per citation, relevance thresholds, session caps, and deduplication windows. This creates a transparent, verifiable citation economy where creators are paid per use of their work, and agents maintain auditable proof of every payment.
