A user enters the prompt “Send a ‘hello’ message to #general channel”.
The LLM calls the messaging tool from Slack’s official MCP server via MCP.
It then responds in chat based on the tool call results.

Other usage examples:

“Find messages related to ‘hotfix’ in #dev channel yesterday”
“Show me the workspace user list”
