"Using the Browser-use library" matching MCP servers:

Provides pay-per-use tools for AI agents like web screenshots and crypto intelligence using automatic USDC micropayments on the Base network. It simplifies access to premium APIs by handling blockchain transactions automatically when a payment is required.

An MCP server that lets AI agents autonomously buy physical hats using USDC on Base — no credit card, no checkout, no human required. Browse the catalog, get a real-time shipping quote, send crypto, and we ship the hat.

A TypeScript library that lets you build MCP servers whose tools charge stablecoins per call and AI agents that pay for those tools automatically via the Machine Payments Protocol on Tempo.

Sovereign, MIT-licensed MCP server for professional service workflow, wrapping the FallRecruit US SDK, enabling offline-capable, Ed25519-signed listing and transaction operations.

A local signing MCP server that lets Claude Code use private keys without ever exposing key material to the model's context window.

Enables ChatGPT and Codex to request public keys, prepare and sign exact Nostr events, encrypt or decrypt NIP-04/NIP-44 payloads, and publish with per-relay acknowledgement, while the private key stays in the user's Alby, nos2x, or remote NIP-46 signer. Every operation is queued for local browser approval, with one-use signing intents and verification before anything is broadcast.

Enables querying indexed blockchain data via subgraph GraphQL queries, part of the Pipeworx MCP gateway.

Enables AI agents to programmatically purchase physical and virtual goods from platforms like Amazon and Shopify using stablecoins, without the need for virtual debit cards or browser automation.

Enables AI agents to use pay-per-use web scraping, Base blockchain analytics, and PDF text extraction tools, monetized via x402 USDC micropayments.

Enables autonomous agents to purchase specialized XRPL market, risk, liquidity, and allocation analysis via MCP and use the results in their economic decisions.

Checks live x402 routes across Base, Solana, and Algorand before agents spend. $0.003 USDC settles only for a valid live eligible route; normal typed misses are not settled. Free preview and validate tools. Seller payment is separate; the agent keeps its wallet. Optional signed route-binding receipts support buyer-side checks.

Provides read-only tools to query live Polymarket prediction-market data via the public Gamma API, enabling search, browsing, and detailed market and event information.

Read-only on-chain query surface for the AgentCivics civil registry on Sui — soulbound AI-agent identities, on-chain memories, reputation, refusal records. Hosted, no install, no keypair. For write tools (register, write_memory, record_refusal), install the npm package @agentcivics/mcp-server locally and supply your own keypair.

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.

Screens the counterparty of an x402 payment before an agent pays it. One tool, screen_payment, checks address sanity, dynamic-payTo swaps, transport safety and your spend policy, then returns allow / review / block with the reasons — advisory only, and by default it runs with no key, no account and no network call.

fomox402 broker + MCP server for last-bidder-wins games on Solana. Drop one URL into Claude / Cursor / Goose / Cline and the agent auto-registers a Privy-managed Solana wallet (faucet-funded with ~0.0024 SOL + $fomox402), bids via x402 micropayments, claims dividends, and plays autonomously. 14 tools wired up — register_agent, place_bid, claim_winnings, claim_dividend, list_games, get_me, etc. Str

Keyless CEX/DEX order signing for AI trading agents (Binance, OKX, Bybit, KuCoin, Hyperliquid, Asterdex). Exchange keys stay inside an AWS Nitro Enclave — the agent gets policy-bounded signatures, never credentials. Built to survive prompt injection and supply-chain key leaks.

Scores and groups caller-supplied Solana launch records using heuristic evidence, exposing tools to analyze deployer reputation through stdio, HTTP API, and Apify integration.

An MCP server that enables cross-chain token transfers via the Stargate protocol.
