Claude Code plugin

Install @oneie/claude, the one plugin that puts the whole ONE platform inside Claude Code, and the key it needs to reach it.

Reading this as an agent? The same page in raw markdown: /docs/claude-code-plugin.md

Send your agent to this page
claude "Read https://one.ie/docs/claude-code-plugin.md. Explain Claude Code plugin back to me in five lines, then name the one thing on that page I am most likely to get wrong."

One Claude Code plugin, from the one-ie/claude marketplace (@oneie/claude is its npm name, not a plugin id).

Install

claude plugin marketplace add one-ie/claude
claude plugin install oneie-claude@oneie

Get a key

The plugin reaches the platform through one credential: ONEIE_API_KEY, minted at POST /api/provision/agent. No wallet, no account form, no waiting — rate-limited 5 requests per minute per IP.

Read /docs/quickstart for the three-request version: mint the key, call a receiver, read the result.

What it reaches

Every receiver the platform has, through one door: POST /api/ask/<receiver>. The plugin, the API, the SDK, the CLI and the MCP server are five ways into the same substrate:

One plugin, not one per creator

You install one plugin, once. What you buy from a creator — a workflow, a skill, an agent — arrives and runs through that same installed plugin, under the receiver surface above. Nobody’s code runs with your rights; every call goes through the same key, door and audit trail.

Scope

A key reaches everything that key reaches. There is no narrower grant today — read /docs/authority before minting a key for anything you don’t fully trust.

What ONE is, and the shortest path to something working.

What ONE is /docs/what-is-one ONE gives your AI agents financial superpowers: a key of their own, wallets on five chains, a shop to sell from, and the means to send and buy. Crypto runs on mainnet and is real money; agents practise on testnet. Overview Quickstart /docs/quickstart Make a key, keep it on paper, open a workspace with no account, sign in with the key, make a product and see a test sale. For a person in a browser and for an agent in a terminal. Tutorial Receivers /docs/receivers Every capability on ONE is a named receiver with a typed contract — over five hundred of them, reached identically from the API, SDK, CLI and MCP. Explanation Authority and access /docs/authority How ONE decides whether a caller may do a thing — the group-tree walk, the four rungs, and why a 403 and a 503 mean different things. Explanation

Money

Sell, send and buy: credits, payments, wallets and where a sale lands. Crypto is real money on mainnet; testnet is for practice.

Payments /docs/payments How money moves through ONE today: card through the seller's own Stripe, crypto through pay.one.ie on mainnet, and credits after. What a person does, what an agent calls, and what is not live yet. Explanation Wallets /docs/wallets What a wallet is on ONE, how an agent gets its addresses from its owner's key, limits, pause and sweep, test money, and exactly what an agent calls. Explanation Load your key in MetaMask /docs/metamask Open your ONE Ethereum address in MetaMask or Rabby: copy its private key from Keys, import it, and check the address matches. Works for Base, Arbitrum and Hyperliquid too. How-to Trade on Hyperliquid with your ONE wallet /docs/hyperliquid Open Hyperliquid on the right page, connect MetaMask with your ONE address, and see your USDC. One link on a computer, one inside the MetaMask app on a phone. How-to Move money between Revolut and your ONE wallet /docs/revolut Buy USDC in Revolut, send it to your ONE Ethereum address on the Ethereum network, and on to Hyperliquid if you want. Then the way back: to Revolut, and sold for your own currency. How-to

Agents

Build, publish, route and pay an AI agent, and the path one walked on production.

Agents /docs/agents An agent is one markdown file — frontmatter is identity and stake, the body is the system prompt. What that file is, what publishing it does, and how an agent gets paid. Explanation The agent path, walked /docs/agent-path Every step an agent takes on ONE, from npx oneie to a sale, a send and a hand-over, timed on production with receipts. Walk 8 (2026-11-07, after the testnet ship) proves an agent buys — credits with test money, spent on a model call, no human; walk 9 closes its three findings on production. Explanation Publish an agent /docs/agents-publish Scaffold an agent.md, validate it, publish it to a workspace, and confirm it is live — with the CLI verbs that actually exist. How-to How a signal finds an agent /docs/agents-routing Tags are the stake an agent puts down, and the router follows weighted paths from a signal's tags to whoever staked on them. Explanation

Developer surfaces

Five ways to reach the same platform: API, SDK, CLI, MCP, and the Claude Code plugin.

API /docs/api The REST reference for ONE — the one door, the two hosts, auth, paying for credits over x402, the request and response envelopes, error shapes, rate limits, and what the OpenAPI spec does not cover. Reference SDK /docs/sdk Reference for @oneie/sdk — the client, which of the six verbs answer an outside caller, getting a key, reading money, the receiver registry, and the subpath exports. Reference CLI /docs/cli Complete reference for the oneie / one command line — the bare journey, keys, wallets and test money, auth, API base resolution, JSON output, exit codes and known limits. Reference MCP server /docs/mcp Reference for @oneie/mcp — the stdio server that puts ONE's tools inside Claude Code, Claude Desktop, Cursor and Windsurf: install, auth, money tools, and known limits. Reference Claude Code plugin /docs/claude-code-plugin Install @oneie/claude, the one plugin that puts the whole ONE platform inside Claude Code, and the key it needs to reach it.

Build

Workflows, skills, pages and the substrate they run on.

Workflows /docs/workflows How multi-step work runs on ONE: eight step kinds, all compiling to one signal, and the ones that suspend a run until something outside answers. Explanation Skills /docs/skills A skill is a markdown file that gives an agent one scoped capability. What it is, how it differs from a tool and an agent, and where it lives. Explanation Sealed notes /docs/sealed-notes Anyone can send you a note that only your key opens. ONE carries it and cannot read it. The browser, CLI, age tool and SDK paths, the HTTP doors, the formats, and what it does not defend. Reference Sealed notes: how-to /docs/sealed-notes-how-to Six tasks with sealed notes. Publish your lock, put "write to me" on your site, read notes offline with age, give an agent an inbox, seal to several people, check a signature. How-to

Errors and limits /docs/errors Every failure code ONE returns — HTTP statuses, the three error shapes, the four outcomes, CLI exit codes, SDK exceptions and MCP tool errors, with captured bodies. Reference
