Test IMAP connection credentials for email migration. Returns folder list with message counts if successful. Requires TREKMAIL_ALLOW_MIGRATION=true.
AI agents call test_migration_connection 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 tests connectivity and retrieves folder/message count information. It performs a read-only probe of an IMAP connection — no data is created, modified, or deleted. The result is informational (folder list with counts). The TREKMAIL_ALLOW_MIGRATION=true requirement is a configuration gate, not an indicator of destructive action.

Register the TrekMail MCP Server MCP server in PolicyLayer and add a rule for test_migration_connection: 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.
test_migration_connection 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 test_migration_connection 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 test_migration_connection. 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.
