"Using AI to control and access data from Home Assistant and smart home devices" matching MCP servers:

A production-ready Model Context Protocol server implementation that connects AI assistants to the TON blockchain, allowing them to query wallet balances, transaction details, smart contracts, and other blockchain data.

This MCP wraps Bitrefill public API to allow agents to search for products and shop using cryptocurrencies like Bitcoin, Ethereum, Solana, and many more.

An MCP server that statically audits Solidity smart contracts for common vulnerabilities like reentrancy and access control, enabling developers to identify and fix security issues via natural language.

Enables AI agents to fetch live multi-chain portfolio, token info, gas prices, and token prices across Ethereum, Base, Polygon, Arbitrum, and Optimism with a single call. No API key required.

Wallet-funded MCP client for six paid Utilia tools: Solana priority fees, transaction diagnosis and simulation, token-risk checks, PDF-to-Markdown, and audio normalization over x402. MIT-licensed and installable from npm.

Signed, outcome-verified smart-money data for Polymarket: which wallets actually win, scored from real on-chain settlement (95% Wilson lower bound over resolved markets) and ed25519-signed so an agent can verify it offline. Whale trades, smart-money consensus and wallet track records, paid per call in USDC over x402, with no account and no API key.

Enables secure interaction with blockchain smart contracts across multiple chains, including ABI analysis, contract method invocation (view/nonpayable/payable), and local wallet management for Ethereum and Base networks.

Monero/Zcash payment webhooks + DeFi liquidation & Ethereum builder data over MCP. Free tier; x402.

Enables AI assistants to access live blockchain data across multiple networks, including wallet holdings, payment verification, token prices, swaps, and scam checks.

Enables scanning Solidity smart contracts for 13 vulnerability classes using pattern-based analysis; provides full audit, quick scan, gas analysis, and detector catalog through MCP tools.

Zero-knowledge proof generation MCP server. AI agents can prove identity claims (Coinbase KYC, Country, Google OIDC, Google Workspace, Microsoft 365) without revealing personal data. Runs in AWS Nitro Enclave TEE with x402 USDC payments.

Enables AI agents to fetch crypto market and on-chain data, including prices across venues, token facts, OHLC candles, market overview, DeFi TVL, and wallet balances, with two free tools and the rest paid per call in USDC on Base via x402.

Enables MCP-capable AI agents to access pay-per-call Solana data such as health, token prices, account balances, transactions, and trending DEX pairs, with automated x402 USDC settlement and no signup or API key required.

Enables MCP-capable AI agents to make pay-per-call Solana data requests (snapshots, risk checks, token reports, health, balances, transactions, trending pairs) with automatic USDC settlement over x402.

23 agent tools: DEX token prices, liquidity, slippage, gas and arbitrage across BNB Chain, Polygon, Arbitrum, Base, Avalanche and Optimism, plus geocoding, weather, web search, URL-to-Markdown, RSS, IP geolocation, holidays, GLEIF LEI lookup and the US Treasury yield curve. 22 are free with no API key, wallet or signup. One paid cross-DEX spread tool pays from your wallet, with hard spend caps.

MCP server for Crypto APIs Block Data product. Get block details by height or hash for EVM, UTXO, and XRP blockchains.

Enables AI assistants to access AnChain.AI blockchain intelligence APIs for risk assessment, sanctions screening, and transaction analysis on blockchain addresses and transactions.

A production-ready MCP server providing comprehensive DevOps capabilities for the Internet Computer blockchain, enabling AI agents to authenticate, manage canisters, handle finances, and build/deploy projects.

Enables AI agents to query crypto data through a hosted remote endpoint: on-chain wallet and token analytics across Ethereum, BNB Chain, Base and HyperEVM, Hyperliquid perp positions and market stats, cohort-based long/short positioning, and Polymarket markets and smart-money flows. Connects via OAuth 2.1 or an API key header from Claude, Cursor, VS Code, and other MCP clients.

Made-to-order data for AI agents via x402 micropayments on Base. Describe a need in plain language, get a custom quote, pay per call. No signup, no API keys. HTTP + MCP transports. 5 tools.
