Fetches a list of your orders (open, closed, canceled, etc.) for an account, optionally filtered by symbol, time, and limit.
AI agents call fetch_order_history to retrieve information from CCXT MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries existing order history data from a cryptocurrency exchange account. It has no capability to create, modify, delete, or execute orders—it only reads and filters existing records.
From the tool's definition Tool name 'fetch_order_history' and description 'Fetches a list of your orders' indicate data retrieval with no side effects. The function only queries historical order data without modifying, deleting, or executing trades.
Documented attack patterns abuse exactly the kind of access fetch_order_history gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and CCXT MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for fetch_order_history:
{
"version": "1",
"default": "deny",
"tools": {
"fetch_order_history": {}
}
}fetch_order_history is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Fetches a list of your orders (open, closed, canceled, etc.) for an account, optionally filtered by symbol, time, and limit. It is categorised as a Read tool in the CCXT MCP Server MCP Server, which means it retrieves data without modifying state.
Register the CCXT MCP Server MCP server in PolicyLayer and add a rule for fetch_order_history: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches CCXT MCP Server. Nothing to install.
fetch_order_history is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the fetch_order_history rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for fetch_order_history. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
fetch_order_history is provided by the CCXT MCP Server MCP server (jcwleo/ccxt-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from CCXT MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
