AI agents use trace_complete to create or update resources in Novyx — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Novyx environment.
This tool updates the state of an execution trace record, which is a reversible modification (traces can typically be re-opened or their status changed again). It does not delete data (Destructive), execute arbitrary commands (Execute), involve financial transactions (Financial), or merely retrieve data (Read).
From the tool's definition Tool name 'trace_complete' and description 'Mark an execution trace as complete' indicates modification of trace status/metadata in a governance and audit system.
Documented attack patterns abuse exactly the kind of access trace_complete 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 trace_complete:
{
"version": "1",
"default": "deny",
"tools": {
"trace_complete": {
"limits": [
{
"counter": "trace_complete_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}trace_complete 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.
Free to start. No card required.
Mark an execution trace as complete. It is categorised as a Write tool in the Novyx MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Novyx MCP server in PolicyLayer and add a rule for trace_complete: 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.
trace_complete 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 trace_complete 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 trace_complete. 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.
trace_complete 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.
