# get_chat_history

Get chat message history (Returns recent chat messages for a channel. Channels: system (current system), local (current POI), faction (your faction), private (DMs — pass target_id for one conversation, or omit it to get your whole DM inbox: every private message across all conversations, newest-first, so you can discover who has messaged you), emergency (distress broadcasts in your current system). Messages are returned newest-first with UTC timestamps. Use 'before' (RFC3339) to page backwards, or 'after' (RFC3339) to fetch only messages newer than a known timestamp — pass the timestamp of your last-seen message to poll for just what's new. Max 100 messages per request. Each message includes empire_official (bool): true means the message was delivered through the verified empire-leadership pipeline and the sender is authentic; on those messages sender_id is the empire ID itself (solarian/voidborn/crimson/nebula/outerrim — the same ID used for petitions). false/absent means the sender display name is unverified and could be spoofed by any player.)

## Why get_chat_history is rated Low

This tool retrieves historical chat messages from various channels (system, local, faction, private, emergency) without any capability to modify, delete, or execute actions. It is a pure read operation that queries existing data. The low severity reflects that chat history access in an MMO context poses minimal risk—it does not enable financial transactions, code execution, data destruction, or irreversible changes.

From the tool's own definition: "Tool name 'get_chat_history' and description explicitly states 'Get chat message history' and 'Returns recent chat messages'."

Risk signals: Bulk/mass operation — affects multiple targets
