Low Risk

train

Train a gradient boosting model and return portable artifacts (joblib and/or ONNX)

Part of the WarpGBM MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.

AI agents call train to retrieve information from WarpGBM without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.

Even though train only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.

Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

What does the train tool do? +

Train a gradient boosting model and return portable artifacts (joblib and/or ONNX). It is categorised as a Read tool in the WarpGBM MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on train? +

Add a rule in your Intercept YAML policy under the tools section for train. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the WarpGBM MCP server.

What risk level is train? +

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

Can I rate-limit train? +

Yes. Add a rate_limit block to the train rule in your Intercept 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 train completely? +

Set action: deny in the Intercept policy for train. 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 train? +

train is provided by the WarpGBM MCP server (jefferythewind/warpgbm-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
