MCP Servers with a list_inboxes tool

Every MCP server Pod knows of that exposes a list_inboxes tool.

9 servers, ordered by decision readiness and adoption — GitHub stars and npm downloads where available, then reported issue volume. None have been dialled by Pod yet, so every tool list here is publisher-reported and unverified.

Inbin

Inbin turns email into a structured, trust-labeled data source for Claude. Every message arriving at your Inbin inbox is extracted against your schema, checked verbatim against the source by a hallucination guard, and served as typed JSON. Each field carries a trust label (typed vs untrusted text a stranger wrote), each event carries the sender's SPF/DKIM/DMARC verdicts, and provenance is channel-derived, so nothing in an email's content can claim authority. Claude can list, search, and aggregate events server-side, wait for confirmation emails to complete signup flows, record decisions, and share individual events across applications by id instead of resending content.

AgentMail

AgentMail gives AI agents their own email inboxes. Through this connector, an agent (or you, in Claude) can spin up a dedicated inbox on the fly, then send, receive, reply to, and forward email, with full thread context, drafts, and attachments, entirely through tool calls. Unlike traditional email APIs built for one-way notifications, AgentMail is built for two-way conversations: an agent can read an incoming thread, understand it, and respond in context, just like a person would. This makes email a first-class communication and identity channel for agents, letting them sign up for services, coordinate with people, and talk to other agents. Key capabilities exposed over MCP: • Inboxes: create, list, get, update, and delete agent inboxes • Messages: send, reply, forward, list, and update • Threads: list, read, label, and delete full conversation threads • Search: full-text search across threads and messages • Drafts: create, list, read, update, send (with scheduling), and delete • Attachments: retrieve attachments by ID, with text extraction for PDF/DOCX Connect in seconds via OAuth using your AgentMail console identity. No API key required in Claude. Sign up free at console.agentmail.to.

AgentMailer

AgentMailer gives every AI agent a durable identity with a unique @agentmailer.ai handle. Agents can send and receive email with people, services, and other agents without borrowing a human inbox.

Agents can also communicate directly through A2A, a standard for discovering another agent’s capabilities and exchanging structured messages, tasks, progress updates, and results. This makes AgentMailer useful for long-running loops and managed agents in Claude that need to delegate work, coordinate with other agents, and preserve communication across sessions.

Through Claude, users can create and manage agent inboxes, search messages and complete threads, access attachments, prepare drafts, send replies, and coordinate agent-to-agent work. Organization-scoped permissions and explicit approval for external actions keep people in control.

CarlyEmail

CarlyEmail gives an agent a real email address it can work from — not a simulation and not a relay through your personal mailbox.

Create an inbox in a single call and it starts receiving straight away. Claude can list and read threads, open attachments, search across mail, file and label messages, draft a reply for you to read, and send once you approve. Drafts are first-class for exactly that reason: an agent writes, a person approves, and only then does anything leave.

Every tool declares what it does before it runs. The thirteen read tools are marked read-only and run without interrupting you. Sending, forwarding, and creating an inbox are marked as reaching the outside world, and deletes are marked destructive, so Claude asks first. Mail that has left cannot be recalled, and the connector is annotated to reflect that rather than treating a send like any other write.

Access is scoped. An API key can be restricted to a single inbox, so an agent given one mailbox cannot read a sibling. Access tokens are bound to this server by audience, so a token minted for another service is rejected rather than honoured. Anything belonging to another organization returns "not found" instead of "forbidden", because confirming that something exists is itself a disclosure.

Built and operated by SWH Labs LLC on infrastructure dedicated to this product. Mail content is stored because handling mail is the product, but it is never sold, never shared for advertising, and never used to train models.

Front

Bring Front — your team's customer operations platform for email and other channels like SMS, WhatsApp, and chat — into Claude. Triage your inbox and draft high-quality replies on any conversation. Ask Claude to summarize a customer's history before a call so you walk in with the full picture in seconds. Analyze conversation data to surface trends across inboxes and accounts, generate reports for stakeholders, and spot emerging issues before they escalate. Because Claude reads the full omnichannel timeline — customer messages, internal comments, assignments, status changes — in one view, it reasons across the full complexity of a customer interaction. Paired with your other connected tools, it can reply and organize work faster and with richer context, so your team delivers exceptional service at scale.

Voxtell Chat

Voxtell Chat is the shared inbox for Voxtell customers: website chat, email, WhatsApp, and SMS conversations in one place, with contacts, labels, canned responses, reports, and a help center.

This connector lets Claude work in that inbox with you. Ask what is open, read a thread and get the gist, draft a reply and post it as a private note or send it, set status and priority, assign a conversation to a teammate, find a contact by name or email, and pull team and inbox reports. Administrators can also manage help center articles.

You sign in with your normal Voxtell Chat email and password on a Voxtell page; Claude never sees your password and only receives a revocable connection. Every tool is labelled read or write, so Claude asks before anything changes. There are no delete tools. Voxtell does not use your conversations to train AI models.

Requires a Voxtell Chat account. Learn more at https://voxtell.com/integrations/mcp.
