MCP Servers with a list_messages tool

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

15 servers, ordered by adoption — npm downloads where a package exists, then reported issue volume. None have been dialled by Pod yet, so every tool list here is publisher-reported and unverified.

Airmail

Airmail MCP connects Claude to the Airmail email client for macOS. Read, search, compose, and organize emails. Manage calendars and reminders. Search contacts. The bridge connects locally to Airmail on your Mac. Data retrieved by AI tools is processed by your chosen AI provider.

Pushwoosh ManyMoney

Pushwoosh ManyMoney connects your AI client to your Pushwoosh project so you can plan, build, launch, and analyze cross-channel messaging with natural-language prompts. Create audience segments and events, draft push, email, SMS, and in-app presets, build and adjust Customer Journeys, diagnose why a message failed, and generate revenue and campaign analytics — without leaving your chat or writing SQL. It also manages apps, API tokens, access, and integrations such as Stripe, Meta, Segment, and Shopify. Every action runs under your own Pushwoosh permissions. To prevent accidental broadcasts, sending live messages is intentionally not exposed.

Strety

Strety is the EOS® software people love — where you can run the Entrepreneurial Operating System with a comprehensive digital toolbox and use built-in Power Ups to manage projects, performance, and engagement — all in one place.

Strety's Claude connector provides secure, real-time access to your Strety workspace, so you can review and act on your company's operating data through natural conversation.

Check a Rock's status, pull this week's Scorecard numbers, see what's on the Issues list, or check who owns a seat on the Accountability Chart. Then act on it: create and complete To-dos, resolve Issues, leave comments, post Headlines and Shoutouts, prep or recap Level 10 meetings, and build projects — all without leaving Claude. Plus, use the connector to connect your other MCP-connected tools with Strety via Claude for a single pane of glass view of your org.

Everything is organized by team and by person, mirroring how your company already works in Strety.

Access is scoped to your own Strety organization and respects your existing permissions — Claude only sees and changes what you already can.

Built for integrators, EOS leadership teams, EOS Implementers™, and people who manage their work lives in Strety. Keep your priorities, metrics, and traction moving between meetings.

Teamtailor

Teamtailor brings your hiring work into the conversation. Ask about your open jobs, see how candidates move through each recruitment pipeline stage, and get quick summaries of a candidate's profile, application, and activity history. You can also act on what you find: move applications between stages, add tags, set custom fields, manage todos, and leave the data ready for your next hiring decision. On the job side, update postings with screening questions, required skills and traits, and interview kits — everything a recruiter needs to keep candidates moving toward an offer. Typical things to ask:

"Which jobs are actively hiring right now?" "Show the hiring pipeline for the Backend Engineer role" "Summarize the candidates in the interview stage" "Who applied this week?" "Move Anna to the next stage and tag her as top-candidate"

Works with your existing Teamtailor account and respects your user's permissions.

Respond.io

The respond.io connector lets you manage your customer conversations and contacts without leaving Claude. Search and update contacts, read and summarize conversation history, send messages across connected channels like WhatsApp, Messenger, and Telegram, assign and close conversations, manage tags and lifecycle stages, and configure AI Agents — all through natural language.

Built for teams that run customer communication on respond.io: support agents can catch up on a conversation and draft replies, managers can review conversation status and reassign work, and marketers can segment contacts with tags and lifecycle stages. The connector respects your respond.io user permissions, so every action is scoped to what your account can already do in respond.io.

MailerSend

The MailerSend connector lets Claude work directly with your MailerSend account so you can handle transactional email without leaving the conversation.

Send email: Compose and send transactional emails — including HTML, plain text, CC/BCC, attachments, and template-based messages. Schedule messages for later, and list, inspect, or cancel scheduled sends.

Domains: Add and configure sending domains, retrieve DNS records, trigger and check domain verification, and update domain settings. Templates: Browse, inspect, and delete email templates in your account. Analytics & activity: Pull delivery and engagement analytics broken down by date, country, and recipient client (user agent name and type). Review message history and recipient activity such as opens, clicks, bounces, and complaints. Email verification: Verify individual email addresses (synchronously or asynchronously) and run bulk verification lists to keep your sending lists clean. Webhooks: Create, list, inspect, update, and delete webhooks to wire MailerSend events into your own systems.

Access is scoped to your own MailerSend account through a secure OAuth sign-in — the connector never sees or stores your API key. Just connect, authorize, and start managing your email in natural language.

Flowera

Flowera is a chatbot studio for building AI assistants that talk to customers on WhatsApp, Instagram and web chat. This connector gives Claude direct access to the AgentFlow builder inside your Flowera workspace.

Describe the assistant you want in plain language and Claude builds it: it adds the nodes, wires the connections, configures the language model, validates the graph and saves it to your workspace as a real, runnable flow. You can then ask Claude to run that flow with a test message and read back exactly what it answered, so you iterate on a conversation design without leaving the chat.

Beyond building, the connector covers the day-to-day work around a live assistant. Claude can list and inspect existing flows, make surgical edits to a single node or connection, declare and trigger webhooks, review recent conversations, and read the leads your assistants have collected.

Everything is scoped to the workspace you choose during sign-in, and permissions are requested separately: reading flows, editing them, running them, reading conversation history and listing credentials are each granted on their own, so you can connect with only what you need. Connected apps can be reviewed and revoked at any time from your Flowera profile.

Requires a Flowera account.

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.

OneSignal

The OneSignal MCP server gives AI agents direct access to OneSignal’s customer engagement platform. Agents can explore users, segments, messages, templates, and analytics; answer product and campaign questions; troubleshoot delivery and engagement issues; generate insights; and help create personalized omnichannel messaging across push, email, SMS, RCS, in-app messaging, and Live Activities.

Carbon Voice

Carbon Voice captures the ideas you speak out loud: voice memos, async voice conversations, async meetings, and direct messages. All voice messages are automatically transcribed. Upload voice memos and get a shareable link. Claude makes them searchable. Ask what was said last week, summarize a long thread, then dictate a new memo or send a reply without leaving the chat.

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.

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.

LMGram

LMGram helps Claude turn concise user intent into opt-in human match requests. Users can create a request from a minimized conversation summary, review recent match requests, and start lightweight chats with matched people. It is designed for finding collaborators, mentors, peers, helpers, beta testers, or domain experts without sharing raw transcripts or unnecessary private context.
