AI agents use amendOrder to create or update resources in Bybit MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Bybit MCP Server environment.
amendOrder modifies an existing open trading order on a cryptocurrency exchange. This is a Write operation (reversible modification), but carries high severity because incorrect modifications to price, quantity, or risk parameters (TP/SL) on live orders can result in significant financial loss, even though it doesn't directly move funds like a Financial category tool would.
From the tool's definition Modify an existing open order. You can update price, quantity, trigger price, take-profit, and stop-loss parameters.
Documented attack patterns abuse exactly the kind of access amendOrder gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Bybit MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for amendOrder:
{
"version": "1",
"default": "deny",
"tools": {
"amendOrder": {
"limits": [
{
"counter": "amendorder_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}amendOrder stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Modify an existing open order. You can update price, quantity, trigger price, take-profit, and stop-loss parameters.\n\n- Either. It is categorised as a Write tool in the Bybit MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Bybit MCP Server MCP server in PolicyLayer and add a rule for amendOrder: 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 Bybit MCP Server. Nothing to install.
amendOrder is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the amendOrder 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 amendOrder. 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.
amendOrder is provided by the Bybit MCP Server MCP server (bybit-exchange/trading-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Bybit 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.
