WHAT IT DOES

What predict_bugs does on Trace

AI agents call predict_bugs to retrieve information from Trace without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why predict_bugs is rated Low

Tool analyzes code metrics and ranks files; produces reports with no side effects or external operations.

From the tool's definition ranks files by metrics, prioritization heuristic, NOT a validated predictor

RECOMMENDED RULE

The rule that runs predict_bugs safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Trace, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For predict_bugs, this is the rule to start with:

predict_bugs Allowed

predict_bugs is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "predict_bugs": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Trace, apply this rule, and every predict_bugs call is checked against it from then on.

FAQ

Questions about predict_bugs

What does the predict_bugs tool do? +

Heuristic bug-risk triage: ranks files by git churn, fix-commit ratio, complexity, coupling, PageRank, and author count — a prioritization heuristic, NOT a validated predictor (calibration notes in the response. It is categorised as a Read tool in the Trace MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on predict_bugs? +

Register the Trace MCP server in PolicyLayer and add a rule for predict_bugs: 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 Trace. Nothing to install.

What risk level is predict_bugs? +

predict_bugs is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit predict_bugs? +

Yes. Add a rate_limit block to the predict_bugs 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.

How do I block predict_bugs completely? +

Set action: deny in the PolicyLayer policy for predict_bugs. 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.

What MCP server provides predict_bugs? +

predict_bugs is provided by the Trace MCP server (nikolai-vysotskyi/trace-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
