Get detailed information about a specific Slack channel.
AI agents call get_channel_info to retrieve information from Slack 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 channel metadata and information without creating, modifying, deleting, or executing any operations. It is a read-only query that returns data about an existing channel. The low severity reflects minimal risk from misuse—an agent could retrieve information about channels it has access to, but cannot cause harm through information disclosure alone in a typical organizational context.
From the tool's definition Tool name is 'get_channel_info' and description states 'Get detailed information about a specific Slack channel.' The verb 'Get' and the absence of any modification, deletion, or execution language clearly indicate a retrieval operation with no side effects.
