AI agents call fetchOpenOrders 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 existing order data from a configured cryptocurrency exchange account without creating, modifying, deleting, or executing trades. It has no side effects and presents minimal risk—it only exposes information about orders already placed by the account holder.
From the tool's definition Tool name 'fetchOpenOrders' and description 'Fetch all open orders using a configured account' indicate data retrieval with no modification or execution. The verb 'fetch' and the read-only nature of querying existing orders confirm this classification.
Documented attack patterns abuse exactly the kind of access fetchOpenOrders 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 fetchOpenOrders:
{
"version": "1",
"default": "deny",
"tools": {
"fetchOpenOrders": {}
}
}fetchOpenOrders is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Fetch all open orders using a configured account. 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 fetchOpenOrders: 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.
fetchOpenOrders 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 fetchOpenOrders 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 fetchOpenOrders. 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.
fetchOpenOrders is provided by the CCXT MCP Server MCP server (lazy-dinosaur/ccxt-mcp). 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.
