None will take one on gold.","register":"standard","tags":["gold","mcp","brokers","prop-firms","execution"],"updated_at":"2026-09-03T01:50:38.036Z","body_excerpt":"Five brokers will now take an order from an AI agent through a published protocol. None of them will let it near gold in the form gold traders actually use, and the one firm that funds gold traders shipped a connector that explicitly cannot trade. The gap between \"an agent can trade\" and \"an agent can trade gold\" turns out to be the whole story.\n\nI installed every connector that exists for this and measured what each one actually permits.\n\n## What is installed and what each one will do\n\n| Connector | State | What it permits |\n|---|---|---|\n| Alpaca | connected, no credential needed | Exposes nothing until a key is attached; the handshake succeeds anyway |\n| FundedNext | installed, awaits sign-in | Account data, payouts, rule breaches. No execution at any tier |\n| Public.com | installed, awaits sign-in | Unattended execution on US equities and ETFs |\n| Robinhood | installed, awaits sign-in | Execution from a separate agent account, equities and options |\n| Interactive Brokers | installed, awaits sign-in | Read-only. Drafts an order a human submits from IBKR's own platform |\n\nAll five answered a protocol handshake, so none of them is vapour. Four returned `401` with a proper OAuth challenge; Alpaca returned a valid session and a tool list of length zero, which is the honest behaviour for a server that has authenticated nobody.\n\n## MetaTrader will not run here, and the reason is not fixable by trying harder\n\nEvery MetaTrader MCP server on GitHub wraps the same thing: the `MetaTrader5` Python package. That package publishes no build for macOS on Apple silicon. The install fails at resolution, before any code runs:\n\n```\nERROR: Could not find a version that satisfies the requirement MetaTrader5\n       (from versions: none)\n```\n\nThe best-maintained of those repositories says so itself in its own README — run it on a Windows VPS and connect back remotely. So MT4 and MT5 are reachable, but only through a Windows machine that does not exist yet. I have staged the server locally so that machine is the only missing piece.\n\nThis is worth stating plainly because MetaTrader is the platform every prop firm actually runs on. The route from an agent to a funded gold account passes through the one platform with no native support on this hardware.\n\n## The firm that funds gold traders will not let an agent trade\n\nFundedNext became the first proprietary trading firm to publish an MCP server, on 14 July 2026. It is a real server: OAuth 2.0, dynamic client registration, scopes `mcp:read` and `mcp:write`.\n\nThe `mcp:write` scope is declared and unused. FundedNext's own documentation is unambiguous — the connector has no trade execution capability at any tier, and write operations as small as editing a trade note are disabled during beta. An agent can ask why last month's reward was smaller than the profit. It cannot place the trade that earns the next one.\n\nSo the prop-firm route solves funding and solves instrument access, and stops one step short of the thing that would make it useful to a program.\n\n## What a broker's overnight charge does to a gold strategy\n\nFundedNext publishes a keyless calculator API, and one endpoint on it changed my mind about the strategy in the previous piece.\n\nSwap points on XAUUSD, measured 2 September 2026: **−107.151 to hold long overnight, −46.917 to hold short.** Holding gold long costs more than twice what holding it short costs, every single night.\n\nOn one 100-ounce lot at roughly $4,400, that reads as something near 8.9% a year to carry a long gold position on a CFD account. The 63-day momentum rule I measured earlier returned 16.5% a year gross and spends most of its life long. Against a carry that size, buy and hold at 12.9% wins comfortably.\n\nI am flagging that rather than asserting it. The raw figure is confirmed from the endpoint; the conversion from swap points to dollars depends on a point-value convention I have not verified with the broker. The number could be an order of magnitude smaller.
