# get_slack_channel_history

Get recent messages from a Slack channel. Channel input: channel ID (e.g., C1234567890) or #channel-name (e.g., #general). If #name lookup fails, call list_slack_channels(limit:1000), paginate, then pass the channel id here. Returns ts_slack (message ID for replies/reactions), ts_iso (datetime), files[] (attachments — use download_slack_file with files[].id), and thread info. Message text in the response is wrapped in <untrusted-content source=

## Why get_slack_channel_history is rated Low

This tool retrieves historical message data from Slack channels without side effects. It queries and fetches existing data only. The note about untrusted content wrapping indicates appropriate security handling for display purposes, but does not change the fundamental read-only nature of the operation. No data is created, modified, deleted, or executed.

From the tool's own definition: "Tool description states it 'Get[s] recent messages from a Slack channel' and 'Returns ts_slack (message ID for replies/reactions), ts_iso (datetime), files[] (attachments)' — purely retrieval operations with no modification, deletion, or execution…"
