Securing AI Agent Access to Crypto Balances and Positions
Summary
The document outlines a security design for letting AI agents read exchange account information through an MCP server. It identifies balances, open positions, unrealized profit and loss, leverage, margin mode, and available funds as useful read-only data for portfolio and exposure reviews.
Its central recommendation is least privilege: use a read-only key for account data, keep trading permissions separate, disable withdrawals, protect secrets with environment variables or a secret manager, and restrict access with IP allowlists and logs. For trading, it proposes a staged workflow in which the agent prepares an action, a risk engine checks it, and a human approves execution.
The article catalogs risks such as prompt injection, stale data, API outages, incorrect tool parameters, and misread margin details. It recommends deterministic risk limits and structured validation, while cautioning that MCP itself is not a risk management system. These are general operational recommendations; the document supplies no measured security outcomes or trading-performance evidence.
Key ideas
- Read-only credentials limit the damage an agent can cause while inspecting balances and positions.
- Separate account-reading tools from trade execution and keep withdrawal permissions disabled.
- Protect API secrets outside prompts and chat logs, and monitor their use.
- Validate position fields and data freshness before using account information for risk decisions.
- Require risk checks and human approval before an agent's proposed trade is executed.
