Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00000 | $0.00303 |
| Opus 5 | $0.00000 | $0.00151 |
| Sonnet 5 | $0.00000 | $0.00061 |
| Haiku 4.5 | $0.00000 | $0.00030 |
Grade A, and why
fx scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
/fx — FX Rate Analysis
Quick FX analysis using the xe-mcp tools. Usage:
/fx NZDUSD → current rate + 30d optimal send window
/fx NZDUSD vol → 30-day volatility analysis
/fx NZDUSD history → last 30 days of daily rates
/fx convert 1000 NZD USD → convert amount
Instructions
When this command is invoked, parse the argument and call the appropriate xe-mcp tool:
$ARGUMENTSis a currency pair (e.g.NZDUSD) → split into from=NZD, to=USD, then call get_rate AND optimal_send_window together and present both results.$ARGUMENTSends invol→ call volatility_analysis for the pair.$ARGUMENTSends inhistory→ call get_historical_rates for the pair.$ARGUMENTSstarts withconvert→ parseconvert AMOUNT FROM TOand call convert.
Present results in a clean, readable format. If the MCP server is not connected, explain how to add it:
claude mcp add xe-mcp node /path/to/xe-mcp/dist/index.js
No credentials needed — Frankfurter (ECB) data works out of the box. Set XE_ACCOUNT_ID and XE_API_KEY for Xe's live rates.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

fx is a command published in the GitHub repository CedricConday/xe-mcp (1 stars, last pushed 1mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 303 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
