Fetch the list of recent trades for a given symbol.
AI agents call fetch_trades to retrieve information from Crypto Multi-MCP Hub without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves historical trade data for informational purposes only. It does not create, modify, delete, or execute any operations. While it operates in a crypto trading context (surrounded by financial tools like create_order, cancel_order), fetch_trades itself is purely informational—it cannot move funds, execute trades, or cause irreversible changes.
From the tool's definition Tool name 'fetch_trades' and description 'Fetch the list of recent trades for a given symbol' indicate data retrieval with no side effects.
Documented attack patterns abuse exactly the kind of access fetch_trades gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Crypto Multi-MCP Hub, and nothing reaches the server without passing your rules. This is the rule we recommend for fetch_trades:
{
"version": "1",
"default": "deny",
"tools": {
"fetch_trades": {}
}
}fetch_trades is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Fetch the list of recent trades for a given symbol. It is categorised as a Read tool in the Crypto Multi-MCP Hub MCP Server, which means it retrieves data without modifying state.
Register the Crypto Multi-MCP Hub MCP server in PolicyLayer and add a rule for fetch_trades: 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 Crypto Multi-MCP Hub. Nothing to install.
fetch_trades 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_trades 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_trades. 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_trades is provided by the Crypto Multi-MCP Hub MCP server (pellenybe/crypto-mcp-server---by-corax-colab). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Crypto Multi-MCP Hub, 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.
