x402 Store Adds MCP Server Support for Pay-Per-Use
Understand the story
On October 5, 2026, a team posted on DEV Community that they had released an MCP server for the x402 store, letting any AI agent call services on a pay-per-use basis without an account or API key. Before payment, the server reads the price and checks it against the limit set by the wallet owner, then completes the payment on Base; if no wallet is configured, it only shows the price and does not execute payment. Tool information is read from the store in real time, so new products don't require updating the server. The team also noted that so far there have been no real sales outside of testing.
