Slack

Connects to Slack's API to handle the most common workspace operations: reading and writing messages, managing threads, and adding reactions. Built by PulseMCP, who focus on minimizing tool chain steps and conversational turns to save both time and inference costs. You'd reach for this when automating Slack workflows through Claude or other MCP clients, whether you're building a support bot that needs to respond in threads, an agent that monitors channels for specific keywords, or just want to send formatted updates without context switching. The stdio transport means it runs locally with your credentials.
