"Using Claude to Create Flowcharts" matching MCP servers:

Provides a pre-signature payment-risk verdict (GO/HOLD/STOP) for x402 payments based on counterparty reputation, price anomaly, and OFAC sanctions.

Pulls Binance spot candle data, computes technical indicators (RSI, MACD, EMAs), and evaluates user-defined bias and risk rules without needing a TradingView session.

Enables interaction with Bitcoin's blockchain through Claude to embed and read data using OP_RETURN, create timestamps, deploy BRC-20 tokens, and store documents up to 100KB on-chain.

Enables ChatGPT users to create and manage Circle developer-controlled wallets on Arc Testnet, check USDC balances, estimate and send USDC using Circle App Kit, and view transaction history.

Enables AI agents to call paid APIs and settle HTTP 402 payment challenges with USDC on Base, without private keys ever being involved.

Enables agents to search and inspect live service offerings, generate x402 payment snippets, and understand blockchain-only balance policies.

MCP server for RugGuard, enabling AI agents to perform pre-trade rug checks on tokens, with paid tools for token scanning and pre-trade verification, and a free metrics resource.

Non-custodial on-chain escrow + AI arbitration for agent-to-agent USDC payments on Base. Seven tools wrap a verified EscrowV1 contract — create, deliver, confirm, dispute, resolve — with read-only introspection if no wallet key is provided.

MCP server for l402-kit — enables AI agents (Claude, Cursor, etc.) to autonomously pay Bitcoin Lightning-protected APIs. Tools: l402_fetch, l402_balance, l402_spending_report. Run with: npx l402-kit-mcp

Converts PDF, Word, Excel, and PowerPoint documents to Markdown using a pay-per-conversion model with USDC on Base via the x402 protocol.

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.

Enables AI agents to discover and pay for x402-gated HTTP APIs, handling 402 Payment Required flows with local signing. Supports EVM and Solana with non-custodial wallet management.

Keyless crypto payments for AI agents. One MCP call turns any wallet address into a non-custodial crypto payment link or tip jar, no API key and no account, with funds settling straight to your wallet at a 0% platform fee (USDC/USDT, BTC, LTC, DASH, DOGE, ZCASH).

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

Enables AI assistants to access live mining data for 126+ proof-of-work networks and 770+ hardware models, including network difficulty, hashrate, solo-mining odds, cost of production, hardware profitability, and mining news.

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.

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.

Enables LLMs to read Binance account history (deposits, withdrawals, trades, balances), market data, and — when trading is enabled — place and manage spot, OCO, TWAP, and convert orders via a plain API key.

fomox402 broker + MCP server for last-bidder-wins games on Solana. Drop one URL into Claude / Cursor / Goose / Cline and the agent auto-registers a Privy-managed Solana wallet (faucet-funded with ~0.0024 SOL + $fomox402), bids via x402 micropayments, claims dividends, and plays autonomously. 14 tools wired up — register_agent, place_bid, claim_winnings, claim_dividend, list_games, get_me, etc. Str

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.
