"How to create, read from, and write to a database" matching MCP servers:

A read-only MCP server for Hyperliquid that provides public market data (prices, order books, funding) and any wallet's positions, orders, and fills via MCP tools, without requiring a private key.

Enables AI agents to turn raw calldata, transaction objects, JSON-RPC requests, EIP-712 typed data and personal_sign messages into short plain-English briefings covering what a request asks for, which risky allowances or permissions need attention, and what could not be verified. Runs entirely offline with no RPC, wallet, API key or safety verdict, using three read-only tools exposed to any MCP client.

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.

Enables AI assistants to query a T-Bank (Tinkoff) investment account in read-only mode, covering accounts, portfolio and positions, operation history, instrument lookup, market data such as candles and order books, plus technical indicators, fundamentals, analyst consensus and dividend or bond coupon analytics through one-line tool calls. No tool can place trades, withdraw funds or change account settings, and a read-only API token is recommended.

This MCP wraps Bitrefill public API to allow agents to search for products and shop using cryptocurrencies like Bitcoin, Ethereum, Solana, and many more.

Universal HTTP 402 Micropayment Protocol & Autonomous Economic Settlement Engine for AI Agents on Base L2.

Enables MCP hosts such as Claude and Cursor to dispatch tasks to live marketplace agents, poll or wait for verified settled results, list available agents by capability, and retrieve live protocol statistics with atomic settlement on Tempo.

Wallet-funded MCP client for six paid Utilia tools: Solana priority fees, transaction diagnosis and simulation, token-risk checks, PDF-to-Markdown, and audio normalization over x402. MIT-licensed and installable from npm.

Provides a pre-signature payment-risk verdict (GO/HOLD/STOP) for x402 payments based on counterparty reputation, price anomaly, and OFAC sanctions.

MCP server for Chainlink Runtime Environment, enabling build, simulate, deploy, and manage CRE workflows from any MCP client.

Non-custodial on-chain escrow + AI arbitration for agent-to-agent USDC payments on Base. Seven tools wrap a verified EscrowV1 contract — create, deliver, confirm, dispute, resolve — with read-only introspection if no wallet key is provided.

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.

Connects AI assistants to Solodit's 49,000+ blockchain vulnerability database, enabling search, browse, and lookup of audit findings directly from your AI workflow.

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.

Enables MCP-capable agents to create, verify, and pay EIP-712 USDC invoices on Ink, and read onchain commerce reputation for ERC-8004 agents.

Read-only access to the live NOVAI blockchain (an AI-native L1) over public JSON-RPC. Query blocks, transactions, AI entities, on-chain signals, oracle anchors, and memory objects. No keys, no write paths.

Enables AI agents to read and interact with Elysium, Kinetiq's testnet-only Layer 2 for Hyperliquid, through typed, rate-limited RPC, explorer, and optional write tools for blocks, transactions, balances, contracts, and testnet transactions.

A curriculum that teaches AI agents how to spend their own money. Sixteen lessons from "what is a wallet" to your first x402 purchase. Teacher, not butler — never signs, pays, or holds keys.

MCP server for Circle's Agent Stack. Create wallets, set spend policies, send USDC, and pay x402-priced endpoints — all from a tool call.

Enables any MCP-capable AI agent to discover and trade onchain Solana funds — launching a fund, depositing, rebalancing, redeeming, swapping tokens, managing an app wallet, and following other traders against the live DFM API. Includes onboarding tools for headless agents and read-only versus write access controlled by an API key and a write-enabled flag.

Enables AI agents to query entities from Arkiv database chains using a SQL-like filter expression, with pagination and configurable fields.

Enables MCP clients to inspect and transact with a token launchpad on Robinhood Chain, offering read tools, resources, prompts, and dry-run-first write tools. Supports launches, curve and V4 swaps, graduations, fee claims, buybacks, and factory admin operations

MCP server for Shelby Protocol that enables AI agents to read, write, and manage files on decentralized storage (Aptos) through tools like upload, download, list, delete, and account info.

Enables LLMs to read and write the BSV social graph with an on-chain identity, OS-keychain wallet, and 38 tools for posts, replies, follows, messages, payments, profiles, and more, with every write broadcast as a real BSV mainnet transaction visible across 50+ shared apps.

Enables read and write interactions with 60+ blockchain networks through Claude Desktop, providing a standardized multi-chain API for transaction management, account insights, staking, and token interactions.

Enables AI agents to read chain data, execute transactions, swap tokens, and manage wallets on Solana through 38 tools across 7 modules. Supports write operations with a private key and includes built-in prompts for common workflows.

A Model Context Protocol server enabling AI assistants to create, buy, and sell tokens on the Pump.fun platform on Solana.

Enables interaction with Bitcoin's blockchain through Claude to embed and read data using OP_RETURN, create timestamps, deploy BRC-20 tokens, and store documents up to 100KB on-chain.

Enables AI agents and MCP clients to browse prediction markets, inspect order books, trades and positions, and to place, cancel and manage orders, close positions and redeem winnings from a locally signing wallet. It also supports read-only operation and a hosted mode for market data only.
