### Description (declared)

# lighter-mcp

A [Model Context Protocol](https://modelcontextprotocol.io) server for [Lighter](https://lighter.xyz) — a zero-fee zk-rollup perpetual DEX on Ethereum.

Connect any MCP-aware client (Claude Desktop, Cursor, Hermes, custom Anthropic SDK apps) and trade Lighter perpetuals natively: place orders, manage positions, set on-chain stop-loss / take-profit, query markets and account state.

## Free + sustained by a small optional fee

**This MCP is free and open-source.** You can install it, run it, and trade through it without paying anyone.

If you find it useful, you can opt-in to a small fee that helps keep the project sustained — one on-chain transaction, no recurring action. The fee is **1 bp maker (0.01%) / 2 bps taker (0.02%)** on your own trades:

| Your trade volume | Per-trade cost (taker) | Yearly cost (50 trades/month) |
|---|---|---|
| $1,000 | $0.20 | ~$120 |
| $100 | $0.02 | ~$12 |
| $50 (lighter sub-account default) | $0.01 | ~$6 |

The fee routes via Lighter's permissionless partner-integrator program to the maintainer's account `725426`. **No fees flow until you sign an on-chain `ApproveIntegrator` once.** It's strictly opt-in: you can install + trade without ever approving.

**Honest disclosure about Lighter's standard fees:**
- Lighter **Standard Accounts** (retail default) currently trade with **0 maker / 0 taker fees**. Approving the integrator means you pay 1-2 bps that wouldn't otherwise apply.
- Lighter **Premium Accounts** trade with 2/20 bps. Approving the integrator gives you 1/2 bps instead — you save money.

For Standard Accounts the approve is a small "thanks" contribution. For Premium Accounts it's a clear win-win.

## How to opt in (or out)

**Opt in (one-time, ~60 seconds, recommended browser flow):**

```bash
lighter-mcp-approve
```

A localhost web page opens; connect Metamask/Rabby; click *Approve*; sign the EIP-191 message in your wallet. Your L1 wallet key never leaves the wallet UI — only an EIP-191 personal signature …
