PayAI x402 Facilitator is an MCP server with 5 tools an agent can call, among them get_discovery_stats, get_supported, list_discovery_resources. It answers at https://facilitator.payai.network/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 6 of 6 times since 12 September 2026; the last check, on 24 October 2026, succeeded.
Verify and settle x402 stablecoin payments; browse the PayAI Bazaar of x402-payable resources.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
get_discovery_stats | Returns aggregate statistics for the PayAI Bazaar catalog and its settlement activity. Use it for a compact view of catalog size and payment volume rather than individual resources. |
get_supported | Returns the payment networks, schemes, assets, and facilitator addresses currently supported by PayAI. Use it before constructing payment requirements when you need live capability data. |
list_discovery_resources | Lists x402-payable resources published in the PayAI Bazaar catalog. Use limit and offset to page through APIs, MCP tools, and agent services available for discovery. Inputs: limit, offset |
settle_payment | Broadcasts the payment on-chain and moves real funds; it is idempotent per signed payload, so resubmitting the identical payload returns the recorded outcome. Treat errorReason "settlement_pending" as unresolved and call again with the iden Inputs: paymentPayload, paymentRequirements, serverExtensions, x402Version |
verify_payment | Verifies a signed x402 payment payload against the supplied payment requirements. It checks validity but moves no funds. Inputs: paymentPayload, paymentRequirements, serverExtensions, x402Version |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://facilitator.payai.network/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.

First indexed 10 September 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
