FNEWSTEER MCP
Claude Installation Guide

Give Claude live awareness of high-impact economic events so you never enter a trade during a news blackout window.

01PREREQUISITES

ℹClaude Desktop only — MCP tools are not available in the claude.ai browser interface. Download at claude.ai/download

04AVAILABLE TOOLS

Tool	What it does
`check_safe_to_trade_now`PRIMARY	Returns SAFE / NOT SAFE for a symbol right now with full blocking event details
`get_upcoming_events`	Lists all high-impact events for the current week
`get_blackout_zones`	Returns avoid-windows as human + machine-readable JSON — ideal for backtesting configs
`refresh_calendar`	Force-busts the cache if you suspect stale data
`get_server_health`	Verifies the data layer is up — use first in automated pipelines

05PROMPT EXAMPLES

BASIC SAFETY CHECK

Is it safe to trade EURUSD right now?

MULTI-PAIR CHECK

Check if any of these are safe to trade right now: EURUSD, GBPUSD, USDJPY

SESSION PLANNING

I'm about to start my trading session. What high-impact news events should I be aware of this week for USD and EUR pairs?

BACKTESTING JSON

Give me all the blackout zones for USD this week in JSON format so I can paste them into my backtest config

FULL WEEK BRIEFING

Give me a complete news risk briefing for this week. Organise it by day, show all high-impact events and their blackout windows.

INCLUDE MEDIUM IMPACT

Check AUDUSD but also include medium impact events in the assessment

⚡ AGENTIC GUARD — PASTE AS SYSTEM PROMPT IN A PROJECT

Before taking any action involving a trade entry, exit, or modification, you must call check_safe_to_trade_now with the relevant symbol. If NOT SAFE, halt and report which event is blocking and when the window clears. Never skip this check.

06NOTES

⚠Cold Starts — The server runs on Render and may sleep after inactivity. The first request after a sleep can take 30–60 seconds. Subsequent requests are fast.

🕐All Times Are UTC — All event times and blackout windows are returned in UTC. Convert to your local timezone as needed.

↺Re-check Before Entry — A SAFE result is a point-in-time snapshot. If more than a few minutes pass between checking and entering, ask Claude to check again.

07TROUBLESHOOTING

Symptom	Fix
Tools don't appear in Claude	MCP is Desktop-only. Confirm JSON is valid (no trailing commas). Fully quit and relaunch.
Connection timeout on first use	Cold start — wait 60s and ask again.
Stale event data	Ask Claude to run `refresh_calendar`
