Overview

AI-generated overview

GasNow is a remote MCP server that gives an assistant live crypto fee data: gas prices, Bitcoin fees, network transfer costs, exchange withdrawals and bridge qu

What you can do
Read live gas prices on EVM chains, with base fee and slow to instant tiers from recent blocks, and Bitcoin mempool fee rates in sat/vB by speed tier. Compare the USD and BRL cost of sending native coins, USDT/USDC and swaps across 12 networks, including Solana, Tron, TON, Bitcoin and Litecoin. Look up exchange withdrawal fees for USDT, USDC and BTC, filtered by exchange, coin and network. Get the cheapest live bridge route and total cost for moving about $100 of stablecoins or ETH/BTC between networks. Pull a full market snapshot as Markdown covering gas, fees, prices, market cap, sentiment and derivatives indices, plus the latest English crypto headlines.
When to use it
Useful when someone asks what it costs to send stablecoins or move funds between chains, which network or exchange is cheapest, or how high gas and Bitcoin fees are right now. Also handy for a quick combined crypto market and news overview.
Requirements
A remote streamable HTTP endpoint; no local runtime, package, account, API key or header is declared. Network access to the hosted endpoint is required.
Before you install
All tools are read-only lookups of live fee and market data; no transactions are signed or sent. Figures are third-party estimates and can change quickly, so confirm costs before acting. News comes from a single external source.

Installation

In SourceWeft

  1. Open GasNow in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.j0n777%2Fgasnow/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows
