SOLx402 MCP Server
MCP server bridging AI assistants to the x402 micropayment protocol on Solana, so agents can discover and pay for services in USDC.
Last commit Feb 6, 2026 · ★ 7
Overview
SOLx402 is an MIT-licensed, open-source MCP server that lets agents such as Claude or Cursor discover x402-enabled services from a facilitator, pay for them in USDC on Solana, and check wallet balances. It's listed on Smithery with setup guides for Cursor, VS Code, and Claude, and flags a 60-second minimum timeout to account for Solana confirmation delays.

State changed on 2026-07-20 (responding → unclear), 2026-09-01 (unclear → failing).
This is the share of our daily checks that succeeded — not an availability guarantee. A check can fail because the host was down, because our runner timed out, or because the network in between dropped it, and only the first of those is a fact about this project. Failures are split by what we can attribute; anything we cannot attribute is counted, not hidden. 44 of these checks predate 2026-09-01, when the probe counted a bot-block (HTTP 403) as a failure and recorded no reason for any failure. Rates spanning that date mix two definitions. Since then: 0%.
