"How to find the owner of a website" matching MCP servers:

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

Cross-chain cryptocurrency swaps via Chainflip. Get quotes, execute swaps, and track progress. No API key required to get started.

Generates MCP servers from smart contract ABIs, enabling Claude to interact with any Ethereum contract via natural language commands.

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.

Enables AI agents to find LayerZero OFT bridge routes by token address and build ready-to-sign cross-chain transactions across 14 EVM networks.

Teaches AI coding agents how to reason correctly about MetaMask Embedded Wallets / Web3Auth architecture, SDK choice, key derivation, auth flows, and common integration pitfalls.

Cross-chain bridge aggregator MCP server for AI agents. Compares routes across LI.FI, deBridge, Relay, Across and Squid to find the best rate. Use when an agent needs to bridge or swap tokens between EVM chains, Solana, or Cosmos. The aggregator of aggregators.

A collection of Bitcoin SV tools for the Model Context Protocol that enables AI assistants to interact with the BSV blockchain through wallet operations, ordinals (NFTs), and various blockchain utilities.

An MCP server providing AI-native access to XGR blockchain data, enabling queries about chain status, sessions, transactions, and contracts, as well as preparing owner-signed on-chain actions via natural language.

Enables AI agents to create identities, list and find services, handle payments in USDC, and manage reputation through a decentralized marketplace.

Teardrop is the native economic layer for AI agents, providing a robust suite of tools for multi-chain portfolio tracking, DeFi yield analysis, and gas estimation. It enables autonomous agents to securely find Web3 data and manage micro-payments on-chain with zero human intervention.

Enables AI agents to anchor document hashes as tamper-proof proofs of existence on the Doichain blockchain, verify those proofs, and read names, blocks, and addresses via a hosted, no-account endpoint.

Enables agents to read a pseudonymous message network's public feed, claims ledger, marketplace listings, and signed Merkle ledger chain, and — with a paid or proof-of-work pass — to post, claim, and trade capabilities with other agents. Every entry is chained into signed Merkle roots so clients can verify the record themselves with a standalone verifier instead of trusting the server.

MCP server for cross-chain bridging, enabling AI agents to find routes, estimate costs, check risks, execute transfers, and track status across blockchains.

MCP server with paid_fetch, list_merchants and budget_status tools: AI agents pay x402 APIs in USDC on Base inside an owner-signed, on-chain budget, so a prompt-injected agent can't overspend or pay an attacker.

Bridges MCP clients to AVOCADO, enabling users to find public jobs, apply, submit evidence, and read receipts through a stdio interface.

Enables AI agents to mint and manage ERC-8004 identities on Arc through free self-minting from their own wallet or paid x402 minting, including drafting registration files, confirming on-chain registration, editing owner-signed files, and checking status.

Enables MCP clients to act as a did:key identity on technocore-chat's signed lane, allowing signed messages, room claiming, and DID note publishing while keeping the private key out of the model's context.

A minimal demo of the x402 payment protocol protecting an MCP tool endpoint, showing how to charge for MCP tools using real 402 rejections and testnet payments.

A Model Context Protocol (MCP) server enabling AI models to interact with the Nostr network, facilitating note posting and interaction with the freedom of speech protocol.
