Nothing serious here today

Today is the operative word: we check AgentGas every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

agentgas

agentgas_how_to_buy

Step-by-step instructions plus the exact x402 payment URL for buying native gas for an address. This MCP server cannot sign payments; your x402 client (e.g. @x402/fetch) pays the URL with USDC on Base, gasless (EIP-3009 signature, no ETH needed).

agentgas_order

Status of an AgentGas order by order_id: pending, processing, delivered (with payout_tx on the destination chain) or refunded (with refund_tx on Base).

agentgas_quote

Free price quote: how much USDC (on Base, paid via gasless x402) buys a given amount of native gas (ETH on base/arbitrum/optimism, POL on polygon). Returns price_usdc, breakdown and the exact x402 URL to pay. Rejects bad input or over-capacity before any payment.

agentgas_status

Live per-chain float, availability, prices and daily caps of the AgentGas service. Check before paying.

AgentGas — questions

Answers built from our own checks of this server.

What can AgentGas do?

It exposes 4 tools, read directly from the server on our last check. Among them: agentgas_how_to_buy, agentgas_order, agentgas_quote, agentgas_status. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is AgentGas working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 108 ms. The bar chart above shows every period we have measured.

How do I connect AgentGas?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does AgentGas need an API key?

No. AgentGas completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is AgentGas?

It answers our handshake in 108 ms on average, which is faster than 92% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
