How to Connect Missive to Claude (and What It Can't Do)
Claude can work with Missive, but through a community-built MCP server or Missive’s REST API — there’s no official one-click Missive connector as of mid-2026 — and either way it only acts inside a chat you open. Wire up one of the community MCP servers with a Missive API token and Claude can read conversations, draft replies, post messages, and manage labels across your shared inboxes. The catch is the shape, not the plumbing: Claude reacts to you asking, in a session, on a paid plan. A customer email arriving in the shared inbox at 2am triggers nothing.
Below: what the Missive API and MCP route expose, the setup, why chat-only hurts for a shared inbox, and how to get triage that fires the moment a message lands.
What the Missive route exposes
Missive runs a full REST API, and a handful of community MCP servers (from stevenayl, grncdr, and the Composio toolkit) wrap it so Claude can talk to Missive directly. Because it rides the real API, the access is genuinely two-way — not read-only like some connectors:
- Conversations. List and read threads across mailboxes, shared labels, and teams (the API requires at least one mailbox filter, and only surfaces conversations the token owner can see).
- Drafting and sending. Create and send email drafts, and post chat messages into a conversation for your teammates.
- Triage actions via posts. Missive recommends posts for automation because they leave a visible trace — close a conversation, move it to the inbox, assign a user, or add labels, all attributed so your team can see what triggered it.
So you can ask Claude things like:
- “Summarize the open conversations in the support inbox and tell me which ones are waiting on us.”
- “Draft a reply to the billing thread from Stripe and assign it to Priya.”
One gating detail: generating an API token requires being on Missive’s Productive plan, and all tokens are personal to a user — there’s no shared org token.
Setting it up
Since there’s no directory connector, the route is an MCP server plus a token:
- In Missive, open Preferences → API and create a new token (Productive plan required).
- Install a community Missive MCP server and add it to Claude with your
MISSIVE_API_TOKEN— locally viaclaude_desktop_config.json, or hosted for a team. - Ask Claude to summarize a mailbox to confirm the connection is live.
Because these servers are community-built rather than Missive-published, treat them like any third-party dependency: read the code and scope the token before pointing it at a live support inbox.
Why chat-only hurts a shared inbox
The inbox never sleeps; the connector does. A shared inbox is defined by things arriving at all hours — a customer replies, a VIP writes in, a thread goes unanswered past SLA. Claude learns about any of it only when a human opens a chat and asks. It can draft a great reply once you’re there; it can’t notice the email that needs one.
No triggers, no schedules. Missive’s own rules can auto-route on arrival — a Spanish message to the Spanish team, a VIP to a senior agent — but those are Missive rules, not Claude. Claude connectors have no event triggers, so “when a new conversation lands, triage it” isn’t something Claude does on its own.
Paid plan, personal token. You need a paid Claude plan for the MCP route and a Productive-plan Missive token that’s scoped to one user’s visibility — fine for a personal helper, awkward as a team-wide autoresponder.
The result: Claude is a sharp desk-side assistant for “help me clear this inbox right now,” and structurally unable to be the one watching the inbox while your team is asleep.
Shared-inbox triage that runs on triggers: Carly
The half Claude can’t do is the reflex: a message arrives and something happens. Carly — an AI executive assistant that runs on triggers, in the cloud — is built for exactly that:
- A new conversation lands in the support inbox → Carly reads it, applies the right label, assigns it to the on-call agent, and posts a suggested reply as a Missive draft — before anyone’s at their desk.
- A customer at Shopify replies to a billing thread → Carly checks the CRM for their plan, drafts the answer with the right numbers, and flags it if the account is at risk of churn.
- A thread sits unanswered past your SLA → Carly bumps it back to the top of the inbox, pings the owner in Slack, and logs the miss to a sheet.
You describe the workflow in plain English — “when a new support conversation arrives, label it, assign on-call, and draft a reply” — and Carly interviews you, then builds it with you. Nothing to host, no token to babysit. AI agents start at $35/month, and workflow steps that don’t use AI run free and unlimited.

Frequently Asked Questions
Does Claude integrate with Missive?
Yes, through Missive’s REST API — usually via a community-built MCP server (from stevenayl, grncdr, or the Composio toolkit) rather than an official one-click connector. With a Missive API token (Productive plan required), Claude can read conversations, draft and send replies, post messages, and manage labels. It acts only inside a chat you open.
Is there an official Missive connector for Claude?
Not as of mid-2026. The available routes are the Missive REST API and community MCP servers that wrap it. Because those servers are third-party, scope the API token and review the code before connecting a live inbox.
Can Claude reply to shared-inbox emails automatically?
It can draft and send replies when you ask it to in a chat, but it won’t reply on its own when a message arrives — Claude connectors have no event triggers. For arrival-triggered triage, assignment, and drafting, use a trigger-based agent like Carly.
What Missive plan do I need for the API?
Generating an API token requires the Missive Productive plan, and every token is personal to one user and scoped to the conversations that user can see — there’s no shared organization token.
What does automated Missive triage cost with Carly?
AI agents start at $35/month, and steps that don’t use AI run free and unlimited — so a label-assign-and-draft pipeline across a busy shared inbox stays affordable even at volume.

See what people say
"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
