Mixmax is the first Gmail-native sales engagement platform with a native MCP server. It links your meeting intelligence - transcripts, summaries, action items - to AI workflows, enabling you to turn conversations into follow-up decks, deal review briefs, business cases, and more.
Connect Claude, ChatGPT, Cursor, Windsurf, or any MCP-compatible AI client to Mixmax and send prompts like "Summarize my meetings from this week" without switching tabs.
Features
Meetings Tool
Access your Mixmax Meeting Intelligence data:
Ask about your meetings - In natural language, ask your AI assistant about upcoming meetings, past meeting transcripts, or meeting summaries. Example: "What did I discuss with Acme Corp last Tuesday?"
Get synthesized intelligence - the AI analyzes your actual Mixmax meeting data to generate summaries, action items, pain points, and next steps—all based on your real conversation history.
Chain it with other tools - Combine Mixmax meeting data with other MCP-connected tools. Pull a transcript, generate a follow-up deck in Gamma, update scripts in Notion - all from one AI conversation.
Share and act - Use the AI's output to prepare for deal reviews, send follow-ups, or brief your manager - all without leaving your AI workflow.

FAQs
Q: What data can the MCP server access right now?
Meeting data - transcripts, summaries, participant lists, and action items. This makes it most useful for customers using Meeting Copilot. We're expanding functionality in upcoming releases.
Q: Does this cost extra?
No. The MCP server is included at no additional cost for all Mixmax customers.
Q: Which AI tools does it work with?
Claude, ChatGPT, Cursor, and Windsurf at launch. Any MCP-compatible AI client will work - we built on open standards.
Q: Is this secure? Can the AI access other users' data?
Yes, it's enterprise-grade. Built on OAuth 2.1 with secure token management, rate limiting, and full tenant isolation. Each user authenticates with their own credentials and can only access their own data.
Q: Can reps take actions through the MCP (send emails, enroll in sequences)?
Not yet - the current beta focuses on meeting intelligence. Action capabilities (sequence enrollment, email sending, template management) are on the roadmap.
Q: Do customers need to be on a specific plan?
No plan restrictions. However, meeting data access requires Meeting Copilot, so the MCP is most valuable for customers already using that feature.
Q: How is this different from just using the Mixmax API?
The API requires technical integration - code, webhooks, and infrastructure. MCP lets any non-technical user connect Mixmax to their AI tool in minutes and interact with their data using natural language. It's the difference between building an integration and having a conversation.
Q: What about Outlook users?
Meeting Copilot is only available to Gmail users.
