Get a single email by ID with full body in LLM-safe format.
AI agents call get_email to retrieve information from Lobstermail without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves email content without altering, deleting, or executing any actions. While email may contain sensitive information, the tool itself performs a simple query/fetch operation. Severity is low because retrieval alone poses minimal risk; the blast radius is limited to information disclosure rather than data loss, code execution, or financial impact.
From the tool's definition Tool description states 'Get a single email by ID' — a retrieval operation with no modification or deletion. The verb 'Get' and the read-only nature of fetching an existing email by identifier are characteristic of Read operations.
Attacks that exploit this kind of access
Get a single email by ID with full body in LLM-safe format. It is categorised as a Read tool in the Lobstermail MCP Server, which means it retrieves data without modifying state.
Register the Lobstermail MCP server in PolicyLayer and add a rule for get_email: 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 Lobstermail. Nothing to install.
get_email 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 get_email 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.
Set action: deny in the PolicyLayer policy for get_email. 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.
get_email is provided by the Lobstermail MCP server (lobster-kit/mcp-server-lobstermail). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
