AI agents call list_missions to retrieve information from Novyx without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns a list of missions scoped to the current tenant. It performs no data modification, code execution, or irreversible actions. The 'list' operation is a classic Read pattern. Severity is low because listing missions exposes information about the tenant's work items but does not execute them or cause other harmful side effects.
From the tool's definition Tool name 'list_missions' and description 'List missions for the current tenant' indicate a retrieval operation with no modification or execution of side effects.
Documented attack patterns abuse exactly the kind of access list_missions gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Novyx, and nothing reaches the server without passing your rules. This is the rule we recommend for list_missions:
{
"version": "1",
"default": "deny",
"tools": {
"list_missions": {}
}
}list_missions is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List missions for the current tenant. It is categorised as a Read tool in the Novyx MCP Server, which means it retrieves data without modifying state.
Register the Novyx MCP server in PolicyLayer and add a rule for list_missions: 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 Novyx. Nothing to install.
list_missions 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 list_missions 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 list_missions. 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.
list_missions is provided by the Novyx MCP server (novyxlabs/novyx-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
