Description
The Gmail MCP Server is the official Google Workspace Model Context Protocol integration, giving AI assistants like Claude, Cursor, and Windsurf direct access to your Gmail account. Built and maintained by the Google Workspace team, the server exposes Gmail as callable MCP tools: search the inbox with Gmail query syntax (from:, subject:, has:attachment, after:), read full email threads including message bodies and metadata, send new messages or reply-to threads, create draft emails for review, manage labels (apply, remove, list), and mark messages read or unread. This makes the Gmail MCP server essential for productivity workflows like "summarize today's unread emails from my team," "find every invoice email from Stripe last quarter," "draft a reply to this thread and label it Follow-Up," or "list all emails with attachments from this client." Authentication requires a Google Cloud project with the Gmail API enabled and OAuth 2.0 credentials configured — download credentials.json from the Google Cloud Console and follow the server's auth setup to generate an access token. Works with Claude Desktop, Cursor, VS Code, and Windsurf. With 1,200+ GitHub stars, it is the most popular official Google productivity integration in the MCP ecosystem.
The Slack MCP server (built by Ivan Korotovsky) connects AI assistants like Claude, Cursor, and Windsurf directly to Slack workspaces, enabling conversational access to your team communication channels without requiring workspace admin approval for a bot install. Its standout feature is a "no permission" stealth mode — it authenticates using your own personal Slack session tokens (xoxc/xoxd, or a stored browser session) rather than requiring a Slack App with OAuth scopes, so it works even in locked-down workspaces where you cannot create bots. It also supports full OAuth Bot Token auth and Enterprise/GovSlack deployments for teams that prefer a conventional app install. Tools exposed include reading channel and DM/group-DM history with smart pagination, searching messages across the workspace, posting messages and thread replies, listing channels and users, and adding reactions. Common use cases include automating standups by posting summaries directly to team channels, searching past Slack conversations to surface decisions or context, monitoring specific channels for keywords or alerts, and drafting replies to thread discussions — all from natural-language prompts. Supports both Stdio and SSE transports plus proxy configuration for corporate networks. Install with: `npx slack-mcp-server@latest --transport stdio`. A separate official-style integration exists from Zencoder (@zencoderai/slack-mcp-server) for teams that prefer standard Bot Token OAuth over session-token auth. Compatible with Claude Desktop, Cursor, VS Code, Windsurf, and Cline.
