Returns categorization buckets without acting. Reports per-bucket counts.
AI agents call inbox_organize to retrieve information from MCP Email Service without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and reports data about email categorization—it queries the state of the inbox and returns statistics without modifying, deleting, or executing any operations. It is a pure read operation with no side effects, making it low-severity.
From the tool's definition Tool description states it 'Returns categorization buckets without acting' and 'Reports per-bucket counts.' The explicit qualifier 'without acting' indicates no modifications or side effects.

PolicyLayer is an MCP gateway — it sits between your AI agents and MCP Email Service, and nothing reaches the server without passing your rules. This is the rule we recommend for inbox_organize:
{
"version": "1",
"default": "deny",
"tools": {
"inbox_organize": {}
}
}inbox_organize is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
