An MCP server that records consented, attributed, paid-for receipts for open-source dependencies, settling per-call USDC payments on Algorand with on-chain attribution.

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.

An MCP server that classifies Polymarket wallets as human or bot, scores their trading edge from 0–10, and streams current open positions.

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.

About An MCP server that provides real-time access to the latest news from Cointelegraph.

Enables querying Polymarket prediction market data, including top active markets and order books, without an API key or database.

CheapestInference — unlimited flat-rate API for frontier open-source LLMs

Enables MCP hosts like Cursor and Claude to query StellarExpert's public Open API for directory entries, asset information, and ledger helper data through exposed tools.
