"A tool for accessing real-time data and making transactions on Solana Blockchain" matching MCP servers:

An open-source, zero-dependency Model Context Protocol (MCP) server and HTTP 402 payment gateway built for Cloudflare Workers and Node.js. This project enables AI agents (Claude Desktop, Cursor, etc.) to natively discover, negotiate, and autonomously pay for digital resources over Solana USDC using standardized MCP tools and standard HTTP 402 Payment Required headers.

Client-side MCP wrapper for Orisha Data's public x402 endpoints, providing free preview tools and paid market data access via x402 payments.

An open-source, zero-dependency Model Context Protocol (MCP) server and HTTP 402 payment gateway template built for Cloudflare Workers and Node.js. This repository provides an automated store API on Solana (USDC) alongside a native MCP Server interface. It enables AI agents (Claude Desktop, Cursor, etc.) to discover, pay for, and consume paid digital assets via standardized MCP Tools.

Provides a three-layer payment firewall for AI agents, enabling identity verification, risk screening, and execution authorization with on-chain policy enforcement for secure and auditable transactions.

Turns messy real estate data into clean, scored, AI-ready property intelligence for Columbus, OH metro, with pay-per-query via x402 micropayments. Enables natural-language search, investment scoring, and enrichment tools for MCP clients.

Enables users to retrieve BIN data for a given BIN number, with optional enhanced attributes for richer insights.

Credit and payments for AI agent developers — over MCP. No crypto required

Free x402 endpoint checker plus paid report and metadata tools. Remote MCP server for agents. Written by AI named Nock, not a human.

Pay-per-call USDC payment proxy for AI agents. Issue scoped Pay Tokens with hard spending caps and auto-journal every charge to freee / Money Forward / QuickBooks.

Enables MCP clients to access all endpoints of an x402 gateway by paying real-time microtransactions (USDC on Base) per API call, with automatic tool discovery and spend guardrails.

A read-only MCP server for securely accessing Xendit payment platform data. It enables querying balances, invoices, transactions, disbursements, refunds, and virtual account payments while preventing any money-moving operations.

agenticpay lets MCP server developers monetize tools via per-call USDC micropayments on Solana, using the x402 protocol. Each tool declares a price; agents pay via signed Solana transactions; settlement happens on-chain in ~1.5–2 seconds.

Fail-closed live-endpoint x402 router. Pay $0.01 USDC on Base, Solana, or Algorand for a live payable URL or an honest miss.

A one-command paywall for local servers that enables testing AI agents' payment flows by simulating HTTP 402 Payment Required responses. It proxies requests with valid payment headers to the actual server, making it easy to develop and test x402 client logic without real blockchain transactions.

RailRouter Lite is a real, production-ready MCP server implementing the Model Context Protocol. It exposes one tool: route_payment. This tool intelligently routes payments to the optimal rail (Stripe MPP, Coinbase x402, or Google AP2) in real time, choosing based on cost, latency, and success rate. Every decision is logged to a Cloudflare D1 database, creating compounding routing intelligence

Provides a 1-line USDC paywall wrapper for any FastMCP tool using the Coinbase x402 protocol, enabling pay-per-call endpoints settled on Base, Polygon, Solana, or Bitcoin Lightning.

MCP server enabling agents to pay for x402 services on the Kaspa blockchain, with tools for checking address, balance, inspecting offers, and making capped payments.

An MCP server that tests agent payment capabilities by making a real x402 payment ($10 USDC on Base) and returning a signed diagnostic report covering the entire payment flow.

Enables human-in-the-loop authorization for AI agent transactions, allowing real-time approval or denial of purchases based on configurable spending limits, vendor blocklists, daily caps, and category restrictions.

A production-ready template for building monetized MCP servers that require per-call payments via the Mainlayer infrastructure. It provides a structured payment gate that ensures AI agents pay for tool usage before accessing server logic or data.
