"How to Connect to a PostgreSQL Server" matching MCP servers:

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

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

A server that exposes blockchain data (balances, tokens, NFTs, contract metadata) via the Model Context Protocol, enabling AI agents and tools to access and analyze blockchain information contextually.

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

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 compile and verify Tolk smart contract code for the TON blockchain.

Enables AI agents to certify documents, prove agreements, and verify counterparty claims with on-chain receipts on Hedera Hashgraph. Provides tools for document certification, two-party attestation, and agent registration with zero-config setup.

Enables agents to mint Ashfields NFTs on Ethereum by burning 100,000 $ASH per token, check wallet and mint status, approve allowances, and trigger royalty distributions.

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

Enables AI agents to look up XRPL domain availability, pricing, profiles, portfolios, and transaction status, and to get registration links for signing in the user's own wallet.

A read-only Model Context Protocol server for the Thru blockchain alphanet, enabling account queries, transaction status, program events, name service resolution, faucet status, and network health via the official @thru/sdk.

A read-only MCP server that lets any MCP-compatible AI agent inspect wallets and contracts on Base directly through natural conversation.

Provides MCP tools to query Etherscan for Ethereum blockchain data—ETH balances, ERC-20 tokens, transactions, contract ABIs, and gas prices—without requiring an API key.

Provides cross-chain bridge and swap tools for AI agents using the Relay Protocol to interact with multiple blockchain networks. It enables agents to query supported chains, obtain transaction quotes, and generate unsigned transaction data for token transfers and swaps.

Thin MCP wrapper around the SQD Portal API for blockchain data queries across multiple networks including EVM, Solana, Bitcoin, Substrate, and Hyperliquid. Provides 25 public tools for discovery, cross-chain queries, and chain-specific operations.

An MCP server for Klever blockchain smart contract development, providing contextual knowledge including code patterns, best practices, and runtime behavior.

Enables AI agents to build, test, deploy, invoke, and inspect Soroban smart contracts on the Stellar network through structured MCP tools and resources.

Read-only MCP server for querying DERO blockchain — blocks, smart contracts, transactions, network info. Privacy-first, runs locally.

Hashlock Markets (hashlock.markets) — sealed-bid intent-based crypto trading protocol with HTLC atomic settlement. AI agents can create, commit, and validate trading intents on Ethereum, Bitcoin, and Sui. Canonical npm package: @hashlock-tech/mcp. Not the cryptographic hashlock primitive, not Hashlock Pty Ltd (hashlock.com).
