Half of Slack Messages Are No Longer From People. Here’s Slack by the Numbers.
Slack reports a surge in AI-driven automation, with 127 million weekly agent actions and 65% of code changes at Anthropic now routed through the platform.
Slack’s roots in human collaboration have expanded to include AI agents, which now execute 127 million automated actions weekly using open standards like MCP. These agents pull real-time context from platforms such as GitHub, Salesforce, and Jira to perform tasks directly within Slack channels. The volume of these MCP tool calls has doubled each quarter, reflecting rapid adoption of agentic workflows in business operations.
At Anthropic, 65% of all code changes are now shipped through Slack, while the platform handles a billion messages daily. The integration of AI agents has transformed Slack from a messaging tool into an execution layer where humans and automated systems work in tandem.
