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 5.1 | $0.00087 | $0.04152 |
| Opus 5 | $0.00044 | $0.02076 |
| Sonnet 5 | $0.00017 | $0.00830 |
| Haiku 4.5 | $0.00009 | $0.00415 |
Grade A, and why
metatradermcp 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 11d 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.
How it starts
The opening of the file, as written. The whole thing — 296 lines — stays where its author put it; the contents beside it link to each section on GitHub.
MetaTraderMCP Server Skill
When to Use
Trigger when the user is working with any of the following:
- MQL4 - MetaTrader 4 programming language (legacy)
- MQL5 - MetaTrader 5 programming language (current)
- MetaTrader 4 (MT4) / MetaTrader 5 (MT5) - trading platforms
- Expert Advisors (EAs) - automated trading bots
- Custom Indicators - technical analysis indicators
- Scripts - one-time execution utilities
- MetaEditor - the MQL compiler/IDE
- MQL4-to-MQL5 migration - modernizing legacy code
Trigger Keywords
mql4, mql5, metatrader, expert advisor, EA, indicator, script, OrderSend, iMACD, iRSI, CopyBuffer, MT4, MT5, MQL, MetaEditor, OnTick, OnInit, OnCalculate, OnStart, PositionOpen, CTrade, SymbolInfoDouble, AccountInfoDouble, iMA, iCustom, OrdersTotal, MarketInfo, .mq4, .mq5, .mqh
Server Overview
The MetaTraderMCP server provides complete local reference documentation for both MQL4 and MQL5, the programming languages used in MetaTrader 4 and MetaTrader 5 trading platforms.
Coverage: 4863 entries across 2 MQL versions, 37 documentation sections, all indexed in ChromaDB.
- MQL5: 2471/2471 sitemap URLs (100%)
- MQL4: 656/656 sitemap URLs (100%)
- 33 MetaTrader5 Python API pages included
- Real MetaEditor compiler integration (local, Wine/CrossOver, or SSH to Windows)
Unlike static docs, this server can actually compile MQL code via the real MetaEditor compiler and return diagnostic reports with error-to-doc cross-referencing.
Mandatory Usage Pattern (NON-NEGOTIABLE)
When working on ANY MQL file (.mq4, .mq5, .mqh, or any file containing OnTick, OnInit, OnCalculate, OnStart, #property indicator, or int OnInit), you MUST consult this server before writing code. Do NOT rely on training data or assumptions.
BEFORE writing a function call or using a built-in:
mql_lookup(name)- exact symbol docs (auto-detects function/variable/type/constant/keyword/operator)- If unsure of the name:
mql_search(query)for semantic hits
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.
