Part of the Mcp Api MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents call retrieveEmailTemplatePreviewWithId to retrieve information from Mcp Api 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 retrieveEmailTemplatePreviewWithId 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.

Creates a preview of the email template provided in the request. This allows you to preview an email template that hasn't been saved to the database yet. The entire email template does not need to be provided on the request. This will create the preview based on whatever is given.. It is categorised as a Read tool in the Mcp Api MCP Server, which means it retrieves data without modifying state.
Add a rule in your Intercept YAML policy under the tools section for retrieveEmailTemplatePreviewWithId. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Mcp Api MCP server.
retrieveEmailTemplatePreviewWithId is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the retrieveEmailTemplatePreviewWithId 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.
Set action: deny in the Intercept policy for retrieveEmailTemplatePreviewWithId. 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.
retrieveEmailTemplatePreviewWithId is provided by the Mcp Api MCP server (@fusionauth/mcp-api). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
