Official MCP Connector for Missive (Read & Write Access for AI Agents)
in progress
Alex Leever
Please build an official MCP (Model Context Protocol) connector for Missive so that external AI agents and tools (Claude, ChatGPT, Cursor, etc.) can interact with Missive data in a secure, structured way.
What we're asking for:
An official, supported MCP server that exposes Missive resources — conversations, messages, contacts, labels, assignments, and drafts — to any MCP-compatible AI client.
Why this matters:
MCP is quickly becoming the standard protocol for connecting AI assistants to external tools and data sources. Without an official Missive MCP connector, users are forced to build their own unofficial integrations (some community members have already done this), which are unsupported, fragile, and lack proper auth scoping.
With an official MCP connector, Missive users could:
- Ask an AI agent to summarize open conversations or flag urgent threads
- Create and send draft replies via an AI agent that has context from multiple tools (CRM, calendar, notes, etc.)
- Build automations that read Missive data alongside other MCP sources (e.g., Pipedrive, Notion, meeting transcripts)
- Use Missive as a full participant in multi-agent workflows
Suggested capabilities (read + write):
- Read: list/search conversations, fetch message threads, get contact details, retrieve labels and assignments
- Write: create drafts, send messages, apply labels, assign conversations, update contact fields
Why now:
MCP adoption is accelerating rapidly across AI clients (Claude Desktop, Cursor, Windsurf, etc.). Teams that rely on Missive as their communication hub deserve a first-class integration, rather than having to work around the gap with screenshots or DIY solutions.
This would be one of the highest-leverage integrations Missive could ship — it opens Missive up to the entire AI agent ecosystem at once.

Can you also ensure we can add Comments and mention people in the Comments

Also ability to access and digest any email attachments would be a huge benefit here, beyond connecting direct to Gmail MCP for example. Like many, I am sure a lot of important info often sits in document attachments

Spark already has it. Come on Missive.

We are really in need of this. This is the only app in our tech stack without an MCP and its causing a lot of friction.

Hopefully, this is being worked on. I've come to the conclusion that the API has some large limitations. Can't see personal labels, no snooze or send & snooze, no archive, no trash.

+1! We are really missing this! Crucial to let AI agents work with Missive too.

Approaching 1 year and still no sign.

I'm a bit surprised that a progressive e-mail/communications app like Missive is so far behind on Implementing what many would consider a foundational feature in 2026. Really hoping this is something in the works and not dismissed by the Missive team as is suggested in one of the comments below.

As AI develops I miss the fact that cannot query conversations as via outlook or gmail we can use ai with those tools to summarise threads and even write emails.
However the core of missive is that there is a conversation and even files that can be added to the conversation around those threads.
Now I actually make 3-4 screenshots and paste to Claude but it’s not a great system.
Any plans for this ?
