"An overview of end-to-end testing" matching MCP servers:

Enables AI assistants to interact with the Solana blockchain, manage accounts and tokens, and develop and deploy smart contracts end-to-end.

An MCP server that exposes live cryptocurrency market data from CoinGecko as 12 typed read-only tools, including prices, market charts, OHLC candles, trending coins, and global market overview.

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

Real-time crypto market intelligence MCP. Get prices, trending coins, market overview, top coins by market cap, and portfolio value — all through natural language in Claude, Cursor, or any MCP client

TON Data MCP Server — real-time blockchain data for AI agents. Provides wallet balances, token prices, STON.fi liquidity pools, market overview, transactions, and network state. 6 MCP tools, free tier, Docker-ready.

Integrates with Rotki portfolio tracker to provide portfolio overview, prices, transaction history, and analytics through intuitive tools for AI assistants.

Enables AI agents to accept non-custodial crypto payments by creating hosted checkout sessions and invoices, tracking payments and wallets, registering and verifying signed webhooks, purchasing prepaid credits, and querying or exporting the book of record. Test-mode payment simulation lets agents verify the full flow end to end.

Enables access to Coinpaprika cryptocurrency data, including coin listings, prices, historical OHLC, market overview, and search through MCP tools.

Enables AI agents to pull end-of-day and historical stock prices, ticker metadata with available date ranges, crypto pair prices at a chosen resample frequency, and recent financial news filtered by ticker or tag. Runs either against a hosted gateway endpoint or locally over stdio, with API-key handling for the account tiers each data source requires.

Enables AI agents and MCP-compatible clients to query live crypto market intelligence—including kimchi premium, DeFi yields, ETF flows, Fear & Greed, funding rates, and market overview—through a hosted standby endpoint without API keys or setup.

Enables an AI agent to settle HTTP 402-gated resources end-to-end: quote conversions, choose from the seller's accepted rails, sign gasless EIP-712 authorizations under enforced per-call and lifetime caps, and verify settlement receipts while tracking wallet balance. Runs self-hosted over stdio or Streamable HTTP, defaulting to testnet with mainnet requiring explicit confirmation.

Travala Travel MCP is the first end-to-end agentic AI travel protocol. It lets AI/ MCP clients search live hotel inventory on 2.2M+ properties, compare room packages and complete bookings, with payment settled on-chain in USDC on the Base network via x402 protocol. OAuth-secured; booking & cancellation are identity- & OTP-protected. Developers earn rewards on bookings driven through their agents.

Lets an agent run a crypto inheritance timer end to end: create switches with recipients and intervals, seal encrypted notes and files locally, check in to restart the countdown, and read or open bundles once they are released — all without leaving the chat client.

Enables AI coding agents to integrate stablecoin crypto checkout into applications by registering workspaces, configuring settlement wallets and webhooks, creating payment links and invoices, and verifying payment status and webhook signatures. It exposes these payment operations as tools over stdio so agents can complete end-to-end payment setup without manual dashboard work.

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

Live Proof-of-Work mining data for AI agents: difficulty, hashrate, solo-mining odds, cost of production and hardware profitability across 126+ networks and 770+ ASIC/GPU/CPU models. Sourced and timestamped, read-only.

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.
