In MT5, Claude or any other MCP client, your trading assistant answers a question about a market from what it remembers, or from a raw quote it has to interpret on the spot. Every answer is a fresh improvisation. Since today it can reach REVDEN instead: one URL, three tools, and a reading that was finished before the question arrived.
The market state arrives as finished labels such as Light Bearish, Aligned or Grade B, with the trend context, the structure and the risk context already attached. REVDEN classifies every covered market on a standing run and pulls fresh data every 5 minutes, so the assistant reads a verdict rather than working one out.
The calendar follows the same rule. Each release is graded by the reaction it actually produced, measured on 3,153 releases from 2021 to 2026, with the percent move and the ATR grading at 15 minutes, 1 hour and 4 hours behind every grade. That measured impact classification overrides the raw label a release arrives with.
New today is the third tool, the Research Register. Every entry in it comes from our own strategy work on the way to an Expert Advisor: the trading ideas we put to the test, and the refinements we tested on our own systems. Behind every verdict stands one standard: a simulation may sort out the hopeless, and the word tradeable is earned in the MT5 Strategy Tester alone, on real ticks, with the spread, commission and swap of a live symbol. Each entry names one rule, one instrument, one timeframe and one window, and the verdict holds for that scope alone. One entry is open in full for everyone: whether a candle strength signal lining up with a support or resistance level lifts a mechanical gold entry on M5. Measured over 28,861 bars, the answer came back no, and the entry says exactly why. That is what the register is for. You start at the edge of what has already been measured, instead of spending months on a direction that was closed here months ago.
The endpoint answers keyless. MetaTrader 5 from Build 6140 takes it under Tools > Options > MCP, Claude Desktop as a custom connector, Claude Code from the terminal, ChatGPT in developer mode, Cursor in its mcp.json, and next to cTrader AI Agent Connect it sits as a second server. Without a key you get the market pulse about two hours behind, the full analysis for the demo symbol of the day, the current calendar day, and the register's open entry.
Your MCP key lives in your profile under MCP Access and comes with the Pro and VIP memberships. Pro switches the same tools to live, refreshed every 5 minutes, across all 34 Forex and gold workspaces, with the calendar up to 72 hours ahead and 30 days back and the measured reaction per release. VIP adds indices and crypto, Deep Market Statistics on calendar events, and the verdicts in the register.
Everything the tools return is a past observation. They describe what has already happened, and the trading decision stays with you.
