Get the current forwarding configuration for a mailbox. Shows whether forwarding is enabled, the target addresses, and keep-copy setting.
AI agents call get_forwarding to retrieve information from TrekMail MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays email forwarding settings for a mailbox. It performs a read-only query of configuration data with no side effects, no data modification, no code execution, and no destructive or financial actions. The only potential sensitivity is that it exposes forwarding target addresses, but accessing configuration data one owns is a standard Read operation.
From the tool's definition Tool description states it 'Get[s] the current forwarding configuration' and 'Shows whether forwarding is enabled, the target addresses, and keep-copy setting.' The verb 'Get' and 'Shows' indicate retrieval of existing data without modification.

Get the current forwarding configuration for a mailbox. Shows whether forwarding is enabled, the target addresses, and keep-copy setting. It is categorised as a Read tool in the TrekMail MCP Server MCP Server, which means it retrieves data without modifying state.
Register the TrekMail MCP Server MCP server in PolicyLayer and add a rule for get_forwarding: 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 TrekMail MCP Server. Nothing to install.
get_forwarding 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_forwarding 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_forwarding. 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_forwarding is provided by the TrekMail MCP Server MCP server (trekmail/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
