"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.

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.

Enables a single owner to run a self-hosted authenticated MCP server that adds Slack reading and replying, Outlook inbox and calendar lookup, signed Slack event capture, restricted KakaoTalk Windows-agent tasks, appointment tracking, and morning briefings to an existing MCP setup.

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.

Enables an AI agent to handle a daily inbox routine by fetching and triaging Gmail messages—archive, star, label, and mark read—and posting summary messages to Slack channels or DMs.

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.

A self-hosted MCP gateway that lets users connect multiple Google, Microsoft, IMAP/SMTP, Notion, Slack, WhatsApp, Luma, and X accounts once, then access them from AI clients such as Claude Code, Codex, Claude, and ChatGPT. It defaults to read-only access, with writes requiring explicit account and client grants.

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 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.
