Eterna MCP Gateway

The fastest way to give your AI agent real trading capabilities.

No KYC. Sandboxed TypeScript SDK. Isolated sub-accounts. 0.014% maker fees on futures.

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.

SDK methods (via execute_code)

29 methods on the eterna object inside the sandbox:

Example:

const balance = await eterna.getBalance();
const ticker = await eterna.getTickers("BTCUSDT");
return { equity: balance.totalEquity, last: ticker[0]?.lastPrice };

Why Eterna?

What you don't have to build

• Sub-account provisioning

• Rate limiting and request validation

• Deposit address management and fund routing

• Error handling for exchange API changes

• A Deno sandbox + typed trading SDK

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

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

Markets
