"How to Use a Web Browser" matching MCP servers:

Local MCP-to-browser signing bridge for EVM, Solana, and Sui, letting agents prepare and simulate transactions while users approve and sign in a browser wallet extension.

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.

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.

⚡ 87% Token-compressed clean web scraping, YouTube AI transcripts, and PDF extraction for LLMs. Instant Free Trial with zero setup (No wallet/crypto required). Supports gasless agent vaults and EIP-712 on-chain oracle verification on Polygon, Base & Arbitrum.

Pay-per-use semantic web search for AI agents. Powered by SearxNG, agents pay in sats via Lightning Network micropayments — no API keys required.

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.

Enables AI agents to create on-chain and web monitors, dead-man switches, cron triggers, and multi-agent coordination with pay-per-use x402 payments.

Use the microservice of testraptor

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

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.

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

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

mcp server that allows to do actual actions related to solana first version adds knowledge about RPC methods and how to call them

A Model-Context-Protocol server enabling users to perform basic operations on Solana and Ethereum blockchains through simple RPC endpoints.

Provides Model Context Protocol access to the ICON MCP v101 API with support for both Bearer token authentication and pay-per-use blockchain payments via the HTTP 402 protocol. It enables AI agents to interact with ICON API endpoints through standardized, asynchronous tools.

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.

Enables AI agents to make pay-as-you-go AI inference requests through x402 with automatic Solana USDC payments, no API keys or registration, while enforcing configurable spending limits.

Enables agents to search and inspect live service offerings, generate x402 payment snippets, and understand blockchain-only balance policies.

Live Proof-of-Work mining data for AI agents: difficulty, hashrate, solo-mining odds, cost of production and hardware profitability across 126+ networks and 770+ ASIC/GPU/CPU models. Sourced and timestamped, read-only.
