WHAT IT DOES

What send_mail does on Webcake Storefront

AI agents invoke send_mail to trigger actions in Webcake Storefront. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why send_mail is rated High

This tool triggers an external operation (sending an email via a CMS automation) whose effects depend on the arguments provided (automation_id, likely recipients and content). Sending email is an external side-effect that cannot be undone once dispatched. It falls under Execute rather than Write because it triggers an external operation (email delivery) rather than simply creating/modifying internal data.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs send_mail safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Webcake Storefront, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For send_mail, this is the rule to start with:

send_mail Rate-limited

send_mail stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

          "max": 10,

    }
  }
}

The button opens the PolicyLayer dashboard: create your workspace, connect Webcake Storefront, apply this rule, and every send_mail call is checked against it from then on.

How do I enforce a policy on send_mail? +

Register the Webcake Storefront MCP server in PolicyLayer and add a rule for send_mail: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Webcake Storefront. Nothing to install.

What risk level is send_mail? +

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

Can I rate-limit send_mail? +

Yes. Add a rate_limit block to the send_mail rule in your PolicyLayer 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 send_mail completely? +

Set action: deny in the PolicyLayer policy for send_mail. 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 send_mail? +

send_mail is provided by the Webcake Storefront MCP server (webcake-storefront-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
