Remote MCPio.github.tang-vu/keryx

One URL. Every agent. Creators get paid.

Give your MCP client a budgeted research tool. Keryx finds relevant writing, settles citation rewards in Arc USDC, and returns the answer with a public receipt.

01 / Setup

Choose your MCP client

The client tag measures which setup path works. It does not identify or authorize you.

Codex

Add once from your terminal. Codex will discover both Keryx tools.

codex mcp add keryx --url "https://keryx.cc/mcp?client=codex"
Setup with an API key
codex mcp add keryx --url "https://keryx.cc/mcp?client=codex" --bearer-token-env-var KERYX_API_KEY
02 / First dispatch

Ask for research, not a search

Tell your agent to use Keryx. The response includes cited creators, reward amounts, confidence, settlement status, and a dispatch URL.

Use Keryx research to explain how micropayments make citation rewards practical for AI agents. Include the paid sources and dispatch receipt.
Anonymous first, verified when ready

Raise the research limit

Try Remote MCP without a key. For higher limits and wallet-level attribution, create an ask-scoped API key in the developer portal. Keryx still funds creator rewards; your key controls identity and rate limits only.
