"How to connect to a database" matching MCP servers:

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

Lets AI agents check whether an EVM wallet address carries an EIP-7702 delegation across eight chains (Ethereum, Base, BNB Chain, Arbitrum, OP, Polygon, Gnosis, Unichain) and learn how to obtain a deeper paid report with delegate bytecode heuristics and risk levels. Read-only, never touching private keys or seed phrases.

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).

Enables MCP clients to connect to Walrus Memory for persistent memory operations like remember, recall, analyze, and restore, with browser-based wallet login and local credential storage.

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 interact directly with the DUAL Web3 Operating System for minting tokens, managing templates, and executing blockchain actions. It provides over 60 tools for handling wallets, organizations, and ZK-rollup infrastructure natively via the Model Context Protocol.

Connects a Bitcoin Lightning wallet to your LLM using Nostr Wallet Connect, enabling payments and interactions with Lightning Network features.

Connect any AI agent to Arcis Protocol DeFi vaults through natural language, enabling deposit, withdrawal, and status queries without SDK or code.

An MCP server that provides access to Stern, a philosophical AI mentor combining rationalist thinking with stoic philosophy to guide users through personalized mentorship and smart contract accountability on Solana.

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

Enables compatible AI clients to connect to a local Coinbase Agentic Wallet through stdio MCP, so they can read wallet status, public address, Base USDC balance, and saved operations without signing, transferring, trading, or making payments.

Enables AI assistants to query evidence-backed DeFi yield data across roughly 17,000 pools — what each pool pays, whether yield comes from base or reward tokens, and how rates have moved over 7/30/90 days. Every figure is dated and linked to its source, and access is read-only without touching wallet keys.

Provides access to Polymarket prediction-market data via Gamma and CLOB public APIs, enabling AI agents to query market information.

An MCP server enabling natural language queries for TON blockchain data, including balance checks, transaction analysis, hot trends, trading patterns, and forensic investigations.

Connect AI agents to the Aevo trading platform. Retrieve market data, manage accounts, and execute trades easily

Provides instant, offline access to a curated intelligence database of 25 Solana/web3 earning platforms, with tools to search topics, retrieve detailed evidence notes, and view verdict, payout rail, and KYC gate statistics.

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.

Enables AI agents to interact with the AI Network blockchain by managing accounts, submitting transactions, and reading database values. It supports registering Hyper Agents and accessing a Layer 2 DAG-based shared agent memory system based on staking status.

A Model Context Protocol server that enables natural language interaction with the TON blockchain, allowing users to perform queries for balances, analyze trading patterns, detect hot trends, and conduct forensic investigations on blockchain data.

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.

Enables users to connect Claude or ChatGPT to a custodial NFT collection and trade by chatting, including minting, buying, selling, listing, checking balances, and withdrawing test tokens.

Enables resolving ENS names to Ethereum addresses and profile records, and reverse-resolving addresses to ENS names, all without requiring an API key.

Enables Claude to increment and query a counter deployed on the Linera blockchain via natural language, using an Apollo MCP server bridge.

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

Provides access to an EVM chain registry, allowing users to browse chains, fetch details by ID or name, and find RPC endpoints with optional filtering.

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

Automated risk triage, liquidity checks, and security guardrails for AI agents operating on the AO / Arweave network.
