"An open-source penetration testing framework" matching MCP servers:

Enables AI agents to inspect and measure live crypto charts, read indicator and market-structure data, add native indicators, and create editable annotations through a local MCP bridge.

Enables AI agents to perform gasless cross-chain transactions by paying with supported tokens on one chain and executing on another, all without exposing private keys.

MCP server for Pi Network that enables AI agents to query Pi chain data (balances, transactions) and verify user tokens, with optional payment sending that is off by default.

An MCP server that mints STAS, DSTAS, and BSV-21 tokens into a BSV Desktop wallet in seconds, enabling rapid token testing and development.

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.

Open-source routing layer that splits compute jobs and inference prompts across resources using Gemini, with MongoDB-backed route books and priced allocations.

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

Enables AI agents to analyze Hyperliquid accounts by retrieving positions, PnL, fills, open orders, and funding through an x402 micropayment MCP server, with no API key or signup required.

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.

A cryptocurrency price service that provides real-time crypto pricing information through an MCP (Model Context Protocol) framework with CoinMarketCap API integration.

Enables searching and retrieving live Solana bounties from Superteam Earn, including full bounty details and currently open feeds, without requiring an API key.

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

Hourly news sentiment and typed market events (hack, regulation, listing, delisting, legal) for 30 crypto pairs, with source links on every signal. Four tools cover the latest score per symbol, history, classified events and the symbol list, and a free API key works out of the box

Enables AI agents to read and bid on a paid message slot on Solana, with enforced spend limits, dry-run proposals, and an append-only audit log for every write.

Keyless MCP exchanger for AI agents — pay an exact amount to one deposit address, EMC delivered to any address. USDT(Tron) > EMC. Live at https://swap.emercoin.com/mcp

Lets an AI agent hire and pay a verified human: post real-world tasks (voice, observation, judgment) and pay in USDC via a non-custodial x402 auth-capture escrow on Base, budget frozen at deploy. Humans verify their X identity before submitting.

pay-per-call x402 API endpoints as MCP tools — web search, page-to-markdown, PDF extract, JSON repair/validate, crypto price, weather, IP geo, DNS, markdown lint + 20 agent-commerce aliases. Each tool proxies to vibes-coded.com and settles via x402 (USDC/Solana). Free-trial endpoints need no auth; paid ones need an x402 signature. Catalog is fetched live, so new endpoints appear automatically.

Keyless CEX/DEX order signing for AI trading agents (Binance, OKX, Bybit, KuCoin, Hyperliquid, Asterdex). Exchange keys stay inside an AWS Nitro Enclave — the agent gets policy-bounded signatures, never credentials. Built to survive prompt injection and supply-chain key leaks.

An MCP server that enables cross-chain token transfers via the Stargate protocol.
