Get details and status of a sent email by its ID.
AI agents call get_email to retrieve information from Unosend MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only retrieves and displays information about an existing email. It does not create, modify, delete, execute code, or affect financial systems. The blast radius of misuse is minimal; an attacker could only view email metadata they may not be authorized to see, which is a confidentiality risk but not a system-level threat.
From the tool's definition Tool description states 'Get details and status of a sent email by its ID' — a pure retrieval operation with no side effects. The verb 'get' and absence of any modification language confirm this is a read-only query.
Attacks that exploit this kind of access
Get details and status of a sent email by its ID. It is categorised as a Read tool in the Unosend MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Unosend MCP Server 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 Unosend MCP Server. 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 Unosend MCP Server MCP server (unosend/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
