"How to Create Workflows in n8n" matching MCP servers:

MCP server for local transaction signing across EVM, UTXO, Tron, and XRP blockchains, with no network calls or API keys required.

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

MCP server for Crypto APIs Prepare Transactions product that builds unsigned EVM transactions for native coin, fungible token (ERC-20), and NFT (ERC-721) transfers.

Enables creating and managing webhook subscriptions for blockchain events such as new blocks, confirmed transactions, and token transfers across major blockchains (EVM, UTXO, Solana, XRP).

MCP server for Crypto APIs Transactions Data. Enables lookup of transaction details by hash across EVM, UTXO, Solana, XRP, and Kaspa blockchains.

Enables AI agents to create wallets, sign transactions, and manage blockchain operations across multiple chains like Ethereum, Solana, and more via Privy.

Enables agents and developers to generate and verify Poseidon Merkle membership proofs, verify Groth16 zk-SNARK proofs, construct and verify Merkle Mountain Range proofs, create SHA-256 Merkle inclusion proofs, and hash EIP-712 typed structured data for private identity and Web3 workflows.

Enables to simulate EVM transactions (dry-run) to preview results, gas usage, and state changes before broadcasting on supported blockchains.

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

MCP server for witnessd, enabling agents to create tamper-evident, signed, and Merkle-anchored certificates of any public URL or API response at a moment in time.

Enables secure management of Squads multisig accounts on the Solana blockchain, allowing LLMs to create proposals, vote, and manage assets. It features built-in security auditing and local private key storage to ensure safe interaction with multisig configurations.

Enables AI agents to create and manage self-custodial ERC-4626 vaults holding a rebalanced basket of tokenized US stocks (NVDA, META, AAPL, GOOGL) on Base, with tools to quote, buy, sell, rebalance, redeem in USDC or in-kind, and transfer shares. Also provides USDC bridging between Base and Arc, gas sponsorship payable in USDC, and x402 payment utilities, with every write returned as unsigned calldata the agent signs itself.

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.

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

mcp server that allows to do actual actions related to solana first version adds knowledge about RPC methods and how to call them

Enables AI agents and LLMs to interact with USDC API endpoints through a standardized Model Context Protocol interface. It provides tools for efficient async handling and seamless integration of USDC functionalities into automated workflows.

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.

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 interact with the AT Protocol ecosystem, including Bluesky, through natural language. Supports public data access without authentication and full write operations with authentication.

Trust infrastructure for AI agents on Base. DEX Spread Oracle (live Uniswap V3 prices), on-chain escrow, insurance pool, and collective knowledge base. 7 smart contracts. Pay-per-query via x402 micropayments in USDC.
