Get full content of an email thread by ID. Returns complete email body, attachments info, and all messages in the thread.
AI agents call get_email_content to retrieve information from Revenue Engine MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries email data without side effects. It does not create, modify, delete, or execute operations—it only fetches existing email content. The severity is low because reading email content, while potentially sensitive depending on authorization context, does not pose immediate operational risk if misused by an agent (no data loss, no financial impact, no external execution).
From the tool's definition Tool description states 'Get full content of an email thread by ID. Returns complete email body, attachments info, and all messages in the thread.' The verb 'Get' combined with 'Returns' indicates pure retrieval with no modification, deletion, or execution.

Register the Revenue Engine MCP server in PolicyLayer and add a rule for get_email_content: 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 Revenue Engine MCP. Nothing to install.
get_email_content 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_content 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_content. 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_content is provided by the Revenue Engine MCP server (promptishoperations/mcpspec). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
