About Obol
Obol is an MCP server published by the GitHub account superbigroach. Find, pay for & call APIs in USDC from AI agents - gasless, sub-cent, 0% commission.
It runs on your own machine: your AI client starts it from the npm package @superbigroach/obol-mcp at version 0.2.2.
It asks for 2 secrets: OBOL_API_KEY and OBOL_AGENT_KEY. Give it a key with the least access that still works.
Version 0.2.2 was published on 30 June 2026, and the source code is public, so you can read it before installing.
Written from the registry entry. 9 automated checks on the registry entry and the package code: 7 pass, 0 warn, 0 fail, 2 info. How we check.
What it asks for
| Variable | Required | Secret | Description |
|---|---|---|---|
OBOL_API_KEY | Yes | Yes | Your Obol API key (obl_sk_live_...) from obol-arc.web.app/settings — identifies your account for listing services and metered calls. |
OBOL_AGENT_KEY | No | Yes | 32-byte hex Arc wallet private key that signs gasless x402/EIP-3009 payment authorizations. Needed only for paying (pay_and_call); discovery and listing work without it. |
