AI agents use optimize_code_by_spec to create or update resources in Trae-OpenSpec MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Trae-OpenSpec MCP environment.
The tool modifies/rewrites code according to specifications, which is a Write operation. It creates or updates code reversibly (optimization can typically be undone or reverted). Severity is medium because code changes could introduce bugs or break functionality if applied incorrectly, but the changes are not inherently destructive.
From the tool's definition Tool name is 'optimize_code_by_spec' and description states it optimizes existing code 'based on OpenSpec specification'. Optimization implies modification of code files.
Documented attack patterns abuse exactly the kind of access optimize_code_by_spec gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Trae-OpenSpec MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for optimize_code_by_spec:
{
"version": "1",
"default": "deny",
"tools": {
"optimize_code_by_spec": {
"limits": [
{
"counter": "optimize_code_by_spec_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}optimize_code_by_spec 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.

根据OpenSpec规范优化现有代码. It is categorised as a Write tool in the Trae-OpenSpec MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Trae-OpenSpec MCP server in PolicyLayer and add a rule for optimize_code_by_spec: 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 Trae-OpenSpec MCP. Nothing to install.
optimize_code_by_spec 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 optimize_code_by_spec 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 optimize_code_by_spec. 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.
optimize_code_by_spec is provided by the Trae-OpenSpec MCP server (leon30083/trae-openspec-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Trae-OpenSpec MCP, 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.
