AgentGas MCP

AgentGas provides cross-chain gas for AI agents, allowing users to pay USDC on Base via x402 to receive native gas on Base, Arbitrum, Optimism, or Polygon. The MCP server exposes read-only tools for quoting, checking status, and retrieving order details.

Endpoint and access

No sign-in to connect and list tools. Individual tools may still need a vendor account, credentials, or permissions; check the documented prerequisites.

Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Read-only helper for AgentGas: quote, live capacity, order status and how-to-buy. Payment itself is an x402 call to /v1/gas (USDC on Base).

agentgas_quote — Quote native gas
Advertised by the server during the last successful anonymous check.
Advertised read-onlyOpen-world

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_order — Order status

Advertised read-onlyOpen-world

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_how_to_buy — How to buy gas
Advertised by the server during the last successful anonymous check.
Advertised read-onlyOpen-world

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).

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http agentgas-mcp https://agentgas.madebydevx.com/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add agentgas-mcp --url https://agentgas.madebydevx.com/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable agentgas-mcp in your MCP settings.
Cursor configuration

}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.
Gemini CLI configuration
gemini mcp add --transport http agentgas-mcp https://agentgas.madebydevx.com/mcp

Claude Desktop

Merge this into claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\), then restart Claude Desktop.

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.
Windsurf configuration
