Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Runs an external command npm/bin/lucyd-mcp.js:72, [пакет] bin/lucyd-mcp.js:72 
    const child = spawn(bin, process.argv.slice(2), { stdio: 'inherit' })

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Full details of one market, including its rules and the ids of its up and down outcome tokens.
markets
list_markets
List prediction markets on Lucyd. Each market asks whether the BTC price will be Up or Down at its end date versus the strike (strike is the price times 1e8). Returns address (the market id), state, period, start and end dates, strike, winner and volume.
order
get_order_book
Order book of a market outcome: bids (best first) and asks with prices in USDC per token and sizes in tokens, plus best bid, best ask and mid. Buying down at p is the same book as selling up at 1 - p.

Lucyd — questions

Answers built from our own checks of this server.

What can Lucyd do?
It exposes 9 tools, read directly from the server on our last check. Among them: get_market, get_order_book, get_pnl_history, get_positions, get_status, get_trader_stats and 3 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Lucyd working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 114 ms. The bar chart above shows every period we have measured.
How do I connect Lucyd?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Lucyd need an API key?
No. Lucyd completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 9 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Lucyd?
It answers our handshake in 114 ms on average, which is faster than 89% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
How many people use Lucyd?
The npm package @lucyd/mcp was installed 103 times in the last week. Week over week that is +296%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Lucyd open source?
The code is open source: it is published under the MIT licence, written in Rust and 0 stars on GitHub. The licence covers the code in the repository, not the hosted service at mcp.lucyd.trade, which runs on its operator's own terms.
