Common questions
Is Macro & Commodities Desk safe?
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed –, and the latest version (1.2.0) reached the registry 25 days ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.
What can I use instead?

PredictionMarketsPicks MCP
Canonical home: predictionmarketspicks.com/mcp — docs, setup, the live wall and the per-tool track record. This repo is the bridge and the offline calculators; the server lives on the site.
A hosted Model Context Protocol server that gives AI agents quant tools for Kalshi and Polymarket prediction markets — expected value, Kelly sizing, Bayesian updating, probability conversion, cross-platform price gaps, Fed rate odds, Kalshi's 15-minute markets and perps (with liquidation estimates), live edge signals, and the in-season NFL model: power ratings, win probability, The Ladder, the weekly prop board and game/prop edges.
Every signal our engines publish is graded against the market that priced it — per tool, wins and losses both, including the engines that lose money. The live record: predictionmarketspicks.com/track-record
- Endpoint (Streamable HTTP):
https://predictionmarketspicks.com/api/mcp/mcp?via=npm - Registry name:
com.predictionmarketspicks/quant(MCP registry) - 40 tools on the main endpoint (
/api/mcp/mcp), 45 across the two hosted servers: the fantasy-draft server addsadp_market_gaps,best_available,compare_players,draft_boardandwho_do_i_draft. No key needed for the free set. Counts read from the livetools/liston 2026-11-03. - Fantasy draft landing page: predictionmarketspicks.com/draft — the eight draft tools, connect instructions, and the model behind the board. During the season all eight answer week-by-week NFL market questions instead of draft questions.
See it work
- Gemini CLI: install in one command, ask which Kalshi 15-minute markets are open. (47s demo · setup)
- Kalshi vs Polymarket, in one question: ask where the two venues disagree, then whether they agree on the next Fed meeting. (50s demo · setup guide)
- Kalshi 15-minute gold & Bitcoin + the BTC perp: live boards and perp funding in one chat. (48s demo · commodity markets)
- Claude, ChatGPT & Cursor: paste one URL and ask. (40s demo · Cursor setup)
- Kalshi weather edges + Kelly sizing: forecast vs market, then the position size, in one chat. (46s demo · weather)
Connect
One click: Add to Cursor · Add to VS Code · Gemini CLI: gemini extensions install https://github.com/predictionmarketspicks/mcp
Any host that speaks Streamable HTTP (Claude Code, Claude.ai, ChatGPT, Cursor) — point it at the URL. Nothing to install:
claude mcp add --transport http predictionmarketspicks https://predictionmarketspicks.com/api/mcp/mcp?via=npmHosts that only speak stdio — this package bridges one to the other:
{"mcpServers": { "predictionmarketspicks": { "command": "npx", "args": ["-y", "@predictionmarketspicks/mcp"] } } }
That relays the hosted server verbatim — all 40 tools on the main endpoint, live data, tool schemas and result payloads untouched. Set PMP_API_KEY in the server's env to unlock the Pro tools; without one you get the free tools at free depth.
npx @predictionmarketspicks/mcp # bridge to the hosted quant server (default)npx @predictionmarketspicks/mcp --draft # bridge to the fantasy-draft server npx @predictionmarketspicks/mcp --local # 6 calculators, offline, no network at all
--local is a self-contained build of the six stateless calculators. It makes no network calls, so it runs in an air-gapped sandbox — but it cannot serve the live engines, the NFL model, or anything that reads a market.
