30-Second Install

Add to your MCP client and complete OAuth when prompted:

{
  "mcpServers": {
    "eterna": {
      "type": "streamable-http",
      "url": "https://mcp.eterna.exchange/mcp"
    }
  }
}

Your agent is auto-provisioned on first sign-in. There is no register_agent tool.

See QUICKSTART.md for Claude, Cursor, and Openclaw walkthroughs.

How it works

Eterna is not a one-MCP-tool-per-exchange-endpoint server.

1. Agent calls search_sdk to find the right eterna.* method.
2. Agent calls execute_code with TypeScript that uses the full SDK in one round-trip.
3. Code runs in a sandboxed Deno runtime. Result is returned as JSON.

That model uses ~90% fewer tokens than wrapping every Bybit call as a separate MCP tool.

Works with your stack

Claude (claude.ai)

Add a custom connector with URL https://mcp.eterna.exchange/mcp, complete OAuth, Approve.

Claude Code / Cursor

Use the JSON config above (Claude Code: .mcp.json, Cursor: .cursor/mcp.json). Complete OAuth when prompted.

Openclaw

openclaw plugins install @eterna-hybrid-exchange/openclaw-plugin
npm install -g @eterna-hybrid-exchange/cli
eterna login

Any Streamable HTTP MCP client

Point the client at https://mcp.eterna.exchange/mcp and authenticate with OAuth (mcp:full) or a legacy Bearer API key. Polished guides for LangChain / CrewAI / AutoGen / ChatGPT are expanding.

---

Authentication

Preferred: OAuth via https://ai-auth.eterna.exchange with scope mcp:full.

Legacy: long-lived agent API keys as Authorization: Bearer … (Argon2 hashed at rest).

Details: docs/authentication.md

Roadmap

See ROADMAP.md.

Shipped: code execution sandbox, OAuth agent provisioning, 29 SDK methods, technical analysis, funding/withdrawal flows.

Next: broader SDK coverage, cron strategy runtime, backtesting, spot.
