AI agents use utility_create_sector to create or update resources in TdxQuant MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your TdxQuant MCP Server environment.
The 'create' verb in the tool name suggests it creates or adds a new sector entity, which is a reversible write operation. However, the empty description prevents confirmation of exact functionality and potential side effects. Within a financial data/trading platform context, creating a sector could affect market data organization or trading logic, warranting medium severity.
From the tool's definition Tool name 'utility_create_sector' indicates a create operation (Write category); description is empty, limiting certainty
Documented attack patterns abuse exactly the kind of access utility_create_sector gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and TdxQuant MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for utility_create_sector:
{
"version": "1",
"default": "deny",
"tools": {
"utility_create_sector": {
"limits": [
{
"counter": "utility_create_sector_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}utility_create_sector 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.
