Low Risk

preview

Retrieve a free preview of a therapy trajectory before purchase. Returns first session content and expected outcomes.

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

AI agents call preview to retrieve information from Overcome Stress 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 preview 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 preview tool do? +

Retrieve a free preview of a therapy trajectory before purchase. Returns first session content and expected outcomes.. It is categorised as a Read tool in the Overcome Stress MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on preview? +

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

What risk level is preview? +

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

Can I rate-limit preview? +

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

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