@nock/mcp
Read-only MCP server for Lighter, by NockTrade. Point Claude (or any MCP client) at it and ask about markets, order books, candles, funding, and any Lighter account.
What it can and cannot do
It has no keys and no write path. Every endpoint it touches is public, so an agent can research and read — it cannot place an order, cancel one, or move funds. That is a property of the code, not a policy: there is nothing here to sign with.
estimate_order_cost prices a hypothetical order (margin, fees, liquidation) and
places nothing.

If trading tools are ever added
Not in this server. A trading server must run on the user's own machine with a key they generated themselves, and needs hard limits an agent cannot talk its way past: per-order and daily notional caps, a market allowlist, reduce-only by default, and explicit human confirmation per order. Orders must never originate from text a tool happened to read — only from the user.
