"How to connect to a SQL Server database" 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.

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.

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.

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.

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.

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 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 agents to query Base blockchain data using natural language by providing contract addresses, SQL templates, and direct access to Coinbase's SQL API for realtime on-chain analytics including DeFi, NFTs, and wallet activity.

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 to discover, purchase, and query blockchain-based datasets using Filecoin/IPFS storage with Ethereum NFT access controls and Lit Protocol encryption. Provides a decentralized marketplace for secure dataset trading with automatic purchase workflows and SQL query capabilities.

Rescues USDC, USDT and USDG from wallets with no gas. Agents check a wallet for stuck or frozen stablecoins, quote a send or a swap into the gas coin, collect the wallet signature and track the transfer. Base, Arbitrum, Ethereum, Polygon, Avalanche, BNB Chain, HyperEVM, Robinhood Chain, Solana and Tron.

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.

MCP server that enables AI signing agents to pre-flight transactions by checking ERC-7730 descriptor safety, explaining function semantics, and scanning contracts for danger primitives.

MCP server that builds unsigned Paraswap token swap transactions for self-custody wallets, holding no keys and signing nothing. It returns raw transaction data for a human to review and approve before execution.

MCP server for OrcaTrace, a pay-per-call Polymarket intelligence feed for AI agents. It provides tools to track smart money, whale entries with calibration, market repricings, and digests across 42K prediction markets, with payments settled via x402 on Base.

Provides live cross-DEX market data on six EVM chains, including per-venue prices, liquidity, and gross spreads with optimal trade sizes. Enables AI agents to query real on-chain data for BSC, Polygon, Arbitrum, Base, Avalanche, and Optimism via MCP tools.

Provides AI agents with direct access to the Ray Group DeFi UX rubric, named patterns, and cognitive-bias glossary for grounded UX assessments of DeFi protocols.

Gives MCP-compatible LLM agents direct access to real-time MEV and DeFi data via Valorem's x402-paid API endpoints, with payments in USDC on Base mainnet.

WaxSeal MCP gives AI agents cryptographic identity — verify any WaxSeal fingerprint, check Ed25519 signatures, and gate irreversible actions with human-signed approval tokens before execution. It connects Claude Desktop, Cursor, and Windsurf to the WaxSeal trust network so agents can prove who authorized an action and reject tampered credentials in under a second.

Enables checking whether a crypto link is a phishing lookalike of a wallet, exchange or dapp by comparing it against official domains and flagging lookalike characters, typosquats, punycode and bait words, fully offline. An optional paid full check adds domain registration age, DNS, redirect tracing and a page scan for seed-phrase prompts and drainer code.

An MCP server that provides real-time web search to AI agents via a pay-per-search USDC microtransaction system.

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