# MCP Servers with a reply_to_message tool Every MCP server Pod knows of that exposes a reply_to_message tool. 8 servers, ordered by decision readiness and adoption — GitHub stars and npm downloads where available, then reported issue volume. Pod has connected to 5 of them; the rest are publisher-reported and unverified. ## [AgentMail](/mcp/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. 24 tools reported — Live, but requires authorization before it will list tools. Publisher lists 24 tools. ## [AgentMailer](/mcp/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. 32 tools reported — Live, but requires authorization before it will list tools. Publisher lists 32 tools. ## [CarlyEmail](/mcp/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. 26 tools reported — Live, but requires authorization before it will list tools. Publisher lists 26 tools. ## [LetsBot](/mcp/letsbot) LetsBot is a WhatsApp Business management platform. This connector lets Claude read and act on your own LetsBot data — contacts, conversations, messages, labels, bot settings, and campaigns — and turn it into reports. Everything is scoped to your account via OAuth; you only ever see your own data. 58 tools reported — Live, but requires authorization before it will list tools. Publisher lists 58 tools. ## [Pumble](/mcp/pumble) Bring Claude into your Pumble workspace to send and manage messages, search past conversations, and handle everyday channel tasks — all directly from your chat with Claude. 19 tools reported — Live, but requires authorization before it will list tools. Publisher lists 19 tools. ## [api.replylayer.ai](/mcp/api-replylayer-ai) ReplyLayer gives AI assistants a real email address that you control. Connect it, sign in to ReplyLayer, and pick which mailboxes the assistant may use: it can act only on those, and you can revoke it from your dashboard at any time. Your assistant can list and read messages and threads, reply in a thread, send new mail, draft and schedule messages, and triage anything ReplyLayer has held for review. Every inbound and outbound message is screened for prompt injection, phishing and unsafe content before your assistant sees it or before it goes out, and each send returns a clear outcome (sent, held for review, or blocked) so your assistant knows what happened. ReplyLayer is for transactional and reply-driven email, not bulk or marketing mail, and requires an account for adults 18 and over. On the free trial you can email anyone who confirms by link, reply to people who write to you, and add up to 10 people you know; add $5 of credit or upgrade to email anyone. 40 tools reported — Publisher-reported; not verified by Pod. ## [Frooition for eBay](/mcp/frooition-for-ebay) Frooition for eBay connects Claude to your eBay store through your Frooition account, so you can work on your listings in plain conversation. Ask Claude which listings are underperforming and why. Each one is diagnosed against your store's normal traffic: not seen in search, seen but not clicked, or clicked but not bought. Claude can run an optimisation report on any listing, covering title, description, item specifics, shipping, returns and compliance, then make the fixes for you. What you can do: - Browse and search your live listings, or look up any item in full - Diagnose performance across your whole store, worst first - Get optimisation reports with the biggest wins first - Update price, quantity, title, description, images, item specifics, handling time, duration, location or design - Bulk update many listings, with a preview of how many will change and any cost first - Create new listings using eBay's category suggestions, required item specifics and your business policies - Upload images to your Frooition media hosting - Preview your Frooition designs on a real listing before applying them Built to be safe: - You sign in with Frooition and choose which eBay accounts Claude can use - Changes to live listings are confirmed by reading back the real result from eBay - Bulk changes need a preview and then your confirmation - Actions that use Frooition credits say so before they run, and credits are refunded if eBay rejects the change You need a Frooition account with an eBay store connected. Toolkit accounts can connect on any plan, including free. Pro and TopDawg accounts need an active subscription. 27 tools reported — Publisher-reported; not verified by Pod. ## [Airmail Desktop Extension](/mcp/airmail-desktop-extension) 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. 102 tools reported — Publisher-reported; not verified by Pod. ## For agents This page has a [Markdown](/mcp/tool/reply-to-message.md) and a [JSON](/mcp/tool/reply-to-message.json) twin. Pod is also queryable over MCP at `https://api.askpod.ai/mcp/read`.
