WHAT IT DOES

What check_versions does on Denpex

AI agents call check_versions 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 / environment file.
`logs`	string	—	Paste logs or an environment dump.

Parameters from the server's own tool schema.

RISK

Why check_versions is rated Low

Even though check_versions 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 check_versions 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 check_versions, this is the rule to start with:

check_versions Allowed

check_versions 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": {
    "check_versions": {}
  }
}

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 check_versions call is checked against it from then on.

FAQ

Questions about check_versions

What does the check_versions tool do? +

Scan logs (or an environment dump like pip list / nvidia-smi) for CUDA / PyTorch / cuDNN / NCCL / driver versions that are known to be incompatible or buggy together, and get the recommended pin. Requires the Team plan or an active trial. It is categorised as a Read tool in the Denpex MCP Server, which means it retrieves data without modifying state.

What parameters does check_versions accept? +

check_versions 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 check_versions? +

Register the Denpex MCP server in PolicyLayer and add a rule for check_versions: 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 check_versions? +

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

Can I rate-limit check_versions? +

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

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

check_versions 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.
