"The official Python standard library documentation" matching MCP servers:

Enables querying indexed blockchain data via subgraph GraphQL queries, part of the Pipeworx MCP gateway.

An MCP server that exposes the python-bitcoinlib API. It provides tools for Bitcoin key management, address generation, transaction building, script operations, and cryptography.

Provides comprehensive access to Ethereum blockchain data through the Etherscan API, including account, block, contract, transaction, token, gas, statistics, logs, and RPC proxy tools.

Enables AI agents to access and search up-to-date Solana documentation, get canonical spec references, and fix Anchor/Pinocchio Solana programs via MCP tools.

An MCP server that lets AI agents autonomously buy physical hats using USDC on Base — no credit card, no checkout, no human required. Browse the catalog, get a real-time shipping quote, send crypto, and we ship the hat.

Reasoning-puzzle arcade for AI agents with seven generated puzzle families, free samples, automatic answer checking, and ranked play from $0.02 USDC on Base via x402. Connect through MCP or HTTP. Browse and try samples without a wallet; run paid tools locally with an explicit spending limit.

498 MCP tools across 12 industry verticals. Marketplace, escrow, DeFi, legal, healthcare, insurance, construction, and trades. USDC payments on Base L2.

Counterparty risk scoring for agentic commerce. Scores wallets, domains, IPs, and companies 0-100 before AI agents transact via x402 micropayments on Base

Enables MCP hosts such as Claude and Cursor to dispatch tasks to live marketplace agents, poll or wait for verified settled results, list available agents by capability, and retrieve live protocol statistics with atomic settlement on Tempo.

On-chain crypto indicators (EMA, RSI, VWAP, Bollinger) via Chainlink oracles.

基于FastMCP的HyperLiquid交易MCP服务器，为AI助手提供市价/限价订单、仓位管理、市场数据等工具，支持与HyperLiquid永续合约和现货交易平台交互。

A backend service that enables interaction with the Binance exchange API, allowing users to view their portfolio, convert tokens, and execute trades with minimal market impact.

Provides programmatic access to the Regen Network blockchain, allowing AI agents to interact with ecological credit markets and track carbon or biodiversity assets. It includes over 45 tools for querying blockchain modules, analyzing marketplace dynamics, and performing portfolio impact assessments.

MCP server for TRON blockchain integration, enabling AI assistants to check balances, manage transactions, interact with smart contracts, and access real-time blockchain data.

A backend service for executing transactions on Binance Smart Chain, enabling secure transfers of BNB and BEP-20 tokens, smart contract interactions, and token creation through structured MCP integration.

Lets a user connect their own AI agent with a personal read-only token so it can read that user's XRPL lending data — vault series, positions, loans, projects and operator queues — as that user sees it, without any ability to buy, sign or change anything.

An MCP server enabling AI agents to browse, claim, submit, and manage paid tasks on the SYNAI Relay agent-to-agent task protocol, with on-chain USDC settlement via x402.

Provides tools for querying onchain data across 12+ blockchain networks, including token balances, transaction analysis, and smart contract security auditing. It enables users to interact with multiple EVM-compatible chains and perform deep contract evaluations through natural language interfaces.

Enables AI agents to interact with the Lido protocol for ETH staking, position management, and governance participation across Ethereum and L2 networks. It provides tools for querying balances, simulating transactions, and executing complex workflows like withdrawals and DAO voting through a safety-first interface.

Pre-trade safety for EVM, Solana and TRON: simulates a real buy and a real sell against live liquidity, so a honeypot shows as a sell that fails instead of a vendor score, and audits a wallet's standing approvals across the three chains. Python standard library only, no API key.
