"browser tool" matching MCP servers:

A tool that enables users to interact with blockchain data to retrieve token total supply, chain IDs, and filtered RPC endpoints across different blockchain networks.

A Model Context Protocol tool that provides weather information for cities, with London access requiring Solana devnet payment via the Latinum Wallet MCP server.

Pay-per-call ($0.005-$0.03 USDC) market and on-chain data API for AI agents and trading bots via the x402 protocol — no signup, no API key. Exposed as a remote MCP server with 12 tools — one free onboarding tool (dump-risk), the rest pay-per-call (kimchi premium, funding rate APR, DEX slippage, token security, arbitrage spread, and more).

MCP server for AI image generation with automatic USDC payments on Base mainnet. Generate, remove backgrounds, and upscale images via simple tool calls.

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

MCP server for Bags on Solana. Reads token analytics, creator-fee data and trade quotes; executes swaps and fee claims only behind a token gate, a hard SOL spend cap, and a single-use confirmation token bound to the exact arguments.
