Trade on Epsilon — the limit-order DEX on Robinhood Chain — straight from your AI agent, in about 30 seconds: install, paste a free API key, then say "buy $20 of WETH if it dips 3%". Non-custodial: orders are EIP-712 messages signed locally, your keys never leave your machine, and funds stay in your wallet until fill.
This plugin bundles:
- MCP server — 12 tools: quotes, token search, portfolio, and non-custodial limit / stop-loss / DCA order placement. Orders are signed locally; keys never leave your machine.
epsilon-tradingskill — teaches the agent the safe trading workflow: quote → approve → place → review, confirmation gates, spend caps, and scheduled position-check recipes.epsilon-api-devskill — teaches the agent to integrate the Epsilon REST API and TypeScript/Python SDKs into bots and apps.- Robinhood Chain rules — chain facts and conventions so code the agent writes for chain id 4663 lands on the right endpoints and signing scheme.
npx skills add alienbase-xyz/epsilon-plugin
Installs the epsilon-trading and epsilon-api-dev skills into Cursor,
Claude Code, Codex, Cline, and 13+ other agent runtimes. Then tell your
agent to set up the MCP server (config below) for live tools.
This repo is also a Claude Code plugin marketplace:
/plugin marketplace add alienbase-xyz/epsilon-plugin
/plugin install epsilon
In Cursor, the plugin prompts for these at install (Configure on the plugin card); elsewhere set them as environment variables:
EPSILON_API_KEY(required) — free self-serve key from developers.epsilon.exchange/dashboard.EPSILON_WALLET_KEY(trading only) — private key of a dedicated trading wallet with limited funds, never your main wallet. Leave empty for read-only mode (quotes, market data, portfolio).EPSILON_REFERRER(optional) — a 0x address that earns the on-chain referral leg of fills you route (permissionless rev-share).
Safety rails are on by default in this plugin's MCP config:
EPSILON_MAX_ORDER_USD=250 (per-order cap, fails closed) and
EPSILON_REQUIRE_CONFIRM=true (the agent must show you a preview and get
your confirmation before any order). Adjust in your MCP settings.
- MCP directly:
npx -y @epsilon-exchange/mcp· hosted read-only:https://api.epsilon.exchange/mcp(X-API-Keyheader) - SDKs:
@epsilon-exchange/sdk(npm) ·epsilon-exchange(PyPI) - Docs: developers.epsilon.exchange · API reference · llms.txt
Trading is at your own risk. Orders placed by an AI agent are your orders. Use a dedicated wallet, keep the spend cap on, and review every confirmation. Epsilon is non-custodial: funds stay in your wallet until a keeper fills your signed order on-chain.
