quanttogo-mcp Read Risk 2/5

AI agents call check_subscription to retrieve information from Quanttogo 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 check_subscription 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 check_subscription tool do? +

Check subscription status and remaining trial days. Requires API key from register_trial.. It is categorised as a Read tool in the Quanttogo MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on check_subscription? +

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

What risk level is check_subscription? +

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

Can I rate-limit check_subscription? +

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

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

check_subscription is provided by the Quanttogo MCP server (quanttogo-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
