"Slack" matching MCP servers:

A privacy-first MCP server for inbox triage, enabling masked email reading, calendar upsert, reply drafting, and Slack digests using Google and Slack credentials.

A multi-channel messaging MCP server that sends messages through Slack, Telegram, Email (Gmail, Naver, Microsoft Graph API), KakaoTalk, and Discord.

Bridges your claude.ai authorized connectors (Slack, Atlassian, Gmail, Google Calendar) to any MCP client, enabling use of those tools without credential setup.

Private MCP server for managing Gmail, custom IMAP/SMTP email, Slack notifications, and personal notes stored in SQLite.

A local-first open-source MCP server that acts as a personal secretary, memory manager, and automation hub—it syncs Calendar, Gmail, Canvas, GitHub, and Health into a typed temporal memory graph, and enables approval-gated write actions like creating events, drafting/sending mail, and filing issues, all with telegram/slack/CLI interfaces and a SQLite-backed audit trail.

Your AI agent can't touch Stripe, Gmail, Slack or more, without your tap. mild.run intercepts every sensitive action and sends you a notification to approve or block — before anything executes. Agent never holds credentials.

A unified MCP server that connects HubSpot, Clay, Apollo, Slack, and email to enable AI agents to execute multi-step GTM workflows such as prospecting, enrichment, CRM updates, and notifications.

A remote MCP server that proxies tool calls to the caller's own Composio account, using their own API key for each request to access services like Gmail, Slack, and Google Sheets.
