analyze_cascade

Analyze a multi-rank distributed-training failure: find the rank that failed FIRST (the others usually just time out waiting on it) and route any GPU Xid faults to the correct node action (reset / reboot / RMA). Runs offline and instantly — provide the gathered per-rank logs via logs, file, or dir.

WHAT IT DOES

What analyze_cascade does on Denpex

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

Parameter	Type	Required	Description
`dir`	string	—	Directory to scan for the newest log file.
`file`	string	—	Path to a log file to read.
`logs`	string	—	Paste the combined per-rank logs.

Parameters from the server's own tool schema.

RISK

Why analyze_cascade is rated Low

Even though analyze_cascade only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

RECOMMENDED RULE

The rule that runs analyze_cascade safely

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

analyze_cascade Allowed

analyze_cascade 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": {
    "analyze_cascade": {}
  }
}

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

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

FAQ

Questions about analyze_cascade

What does the analyze_cascade tool do? +

What parameters does analyze_cascade accept? +

analyze_cascade accepts 3 parameters: dir, file, logs. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on analyze_cascade? +

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

What risk level is analyze_cascade? +

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

Can I rate-limit analyze_cascade? +

Yes. Add a rate_limit block to the analyze_cascade 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 analyze_cascade completely? +

Set action: deny in the PolicyLayer policy for analyze_cascade. 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 analyze_cascade? +

analyze_cascade is provided by the Denpex MCP server (denpex-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
