@arikusi/deepseek-mcp-server Execute Risk 2/5

// WHEN AI AGENTS USE THIS TOOL

AI agents invoke argument_validation to trigger processes or run actions in Deepseek. Execute operations can have side effects beyond the immediate call -- triggering builds, sending notifications, or starting workflows. Rate limits and argument validation are essential to prevent runaway execution.

// WHY ENFORCE A POLICY ON ARGUMENT_VALIDATION

argument_validation can trigger processes with real-world consequences. An uncontrolled agent might start dozens of builds, send mass notifications, or kick off expensive compute jobs. Intercept enforces rate limits and validates arguments to keep execution within safe bounds.

// RECOMMENDED POLICY

Execute tools trigger processes. Rate-limit and validate arguments to prevent unintended side effects.

// FAQ

What does the argument_validation tool do? +

Analyse arguments for logical fallacies. It is categorised as a Execute tool in the Deepseek MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on argument_validation? +

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

What risk level is argument_validation? +

argument_validation is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit argument_validation? +

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

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

argument_validation is provided by the Deepseek MCP server (@arikusi/deepseek-mcp-server). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
