"Setting up SQL Server connections for agent querying" matching MCP servers:

Pay-per-task AI agent for writing, research, code, DeFi & blockchain. Pay in USDC on Base or Solana. Supports A2A, MCP, x402 and Agentmail protocols.

Enables agents to purchase and use compute resources on Robinhood Chain via x402 payments. Provides tools for thinking, renting GPUs, checking balances, and viewing the compute menu.

A local, self-custody MCP server that lets an AI agent trade the Cessio RFQ desk as both maker and taker, holding its own key and signing trades with operator-set limits.

MCP server that lets AI agents scrape web pages as clean markdown for a micro-payment in USDC, using the x402 protocol on Base network. No API keys or signup required.

Agent-Q is an MCP server that separates execution surfaces from signing authority, enabling secure Sui signing flows where the signing device holds keys and policy while requesters submit bounded signing requests through a local host process.

An MCP server that audits ERC-8004 agent registrations, diagnosing issues and providing fix lists.

An autonomous MCP server that fetches datasets from IPFS/Filecoin, performs computation (anomaly detection, statistics, data quality scoring), and stores results via Multi-Chain Storage simulation.

Provides MCP tools to enforce spend policies (allow, deny, step-up, allowlist) on agent wallets with an immutable audit trail.

Enables AI agents to inspect the public NFH protocol corpus, verify census status, and prepare bounded Ethereum wallet intents for claims and non-custodial market actions while never signing or submitting transactions.

Enables AI agents to securely execute peer-to-peer tasks on the XRP Ledger by locking payment in escrow, submitting proof of completion, and receiving an objective PASS/FAIL judgement from an independent AI referee.

An MCP server that gives autonomous coding agents deterministic, schema-validated tools for EVM smart contract development — security scanning, gas profiling, compiler diagnostics, and transaction simulation.

Deploys AI agents on-chain into the Metaplex Agent Registry on Solana, minting Core assets with EIP-8004 identity. Supports self-custodial signing via server keypair or external wallets, with devnet support for free rehearsal.

Reputation scoring for AI agent wallets on Base. 9 tools for trust scores, fraud checks, blacklist lookups, leaderboard, badge generation, and agent registration with x402 payment verification.

An MCP server that lets your AI coding agent (Claude Code, OpenClaw, Codex, Cursor, etc.) discover and pay on-chain agents registered on ERC-8004, using Coinbase's official x402 protocol. No smart account. No bundler. No relay. Just your EOA, an HTTPS request, and an automatic 402 → sign → retry flow.

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

This MCP server enables agents to trade LOOT tokens, play the full loot game loop, and launch their own tokens on Robinhood Chain, all at the same prices and rules as human wallets.

The MCP gateway that lets any AI agent discover and pay metered APIs on Base or Solana — without the user wiring payments themselves.

Read-only MCP server for discovering and ranking on-chain agents on Stellar mainnet via natural language search, reputation probes, and profile lookups.

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.

Paper-trade crypto spot, futures, and prediction markets on CoinRithm with a user-minted API key. Simulated funds only; includes 21 MCP tools and Agent Arena performance tracking.
