Official MCP Connector for Missive (Read & Write Access for AI Agents)
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.

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.

MCP Server For Claude / Open AI
Neal Bailey
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 ?

Hi All check out https://composio.dev/toolkits/missive You can set up a Composio account for free and then you can access Missive that way you get 25,000 tool calls a month

Model Context Protocol (MCP) for Missive

Request to add support for the Model Context Protocol (MCP) for Missive.
The goal is to enable integration of Missive with agents and tools that use MCP, allowing secure and standardized communication between Missive and AI models.
This would simplify the creation of AI-driven automations and advanced workflows without the need for custom integrations.

they're tracking this one as primary feature request: let's concentrate votes pls - https://feedback.missiveapp.com/feature-requests/p/model-context-protocol-mcp-for-missive

FYI: If you need a Missive MCP server today, our friends at Relay made a great guide on building one with their platform: https://docs.relay.app/app-specific-faqs/missive

Phil Langlois Thanks Phil. The problem is that it uses the Missive API, which lacks features that are required for many AI workflows. For example, mark as read, archive, full text search, send an existing draft, etc. So we either need a more robust API or we need a real missive MCP that incorporates these missing features.
Mark Bayly
Any updates. The big MCP Server announcement but it is only to access external data from inside missive. What's happening on this request? Your Reddit says there are no plans to implement this. Is that true?
Garratt Grenier
This is the most important feature tthey could add. If they don’t do it, someone else will.

Hopefully this is imminently on the way!! It's essentially the final piece of the puzzle to pull every different comms channel together into an AI chat window so it has constant full context.
