Introduction

The Delta Exchange MCP server exposes Delta Exchange's market and account data — and, when you opt in, live trading — as Model Context Protocol tools. Install it once and any MCP client (Claude Desktop, Claude Code, Cursor, VS Code, Codex, Zed, or Windsurf) can read live tickers, order books, your positions, and fills, and manage orders, in plain language.

What it does

The server ships 27 read-only tools across two groups, plus 13 trading tools you enable explicitly:

• Market data (14 tools, no key): tickers, order book, candles, open interest, funding, options chain, indices, recent trades, settlement prices, product and reference metadata.
• Account data (13 tools, Read Data key): positions, wallet balances, fills, order history, open orders, wallet transactions, bulk CSV export, configured leverage, profile, trading stats.
• Trading (13 tools, Trading key + DELTA_MCP_MODE=trade): place, edit, and cancel orders (single and batch), brackets, leverage, position margin, and close-all. Off by default.

See the full Tool Reference.

Read-only by default, trading by opt-in

Out of the box every tool is a read-only GET — the server cannot place an order or move funds. Trading registers only when you set DELTA_MCP_MODE=trade and supply a key with Trading permission. Even then, every mutation is dry-runnable, written to a local audit log, and never auto-retried, and the server has no withdrawal path at all. More in Security.

How it runs

The server runs as a local subprocess on your machine and talks to your AI client over stdio. Your API credentials are read from your local environment and used only to call Delta's API directly from your machine. They never pass through the AI model or any Delta server beyond the normal trading API.

Who it's for

• Traders who want a conversational morning brief, funding monitor, or risk scan — and, when they opt in, to place and manage orders in plain language.
• Quants and developers who want Delta market and account data inside an agent or notebook with zero boilerplate.
• Anyone doing P&L, tax, or settlement reconciliation who would rather ask a question than export spreadsheets.
