# MCP Servers with a list_threads tool Every MCP server Pod knows of that exposes a list_threads tool. 8 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. ## [Ninjo](/mcp/ninjo) Ninjo turns Instagram and WhatsApp inboxes into a 24/7 sales channel: AI agents that answer DMs, qualify leads, follow up, and book calls or sales for creators and businesses. This connector lets Claude operate your Ninjo workspace end to end. With it, Claude can: - Create and iterate agents: system prompts, SDK configuration, triggers (keywords, comments, ads, story replies), voice replies, and context documents - Wire the automation around each agent: custom properties, contact limits, follow-up workflows, and operator notifications - Analyze performance: real conversations, funnel metrics, agent insights, and diagnostics that return ranked defects with the exact fix - Test safely: generate synthetic conversations against an agent before going live - Manage content: knowledge documents, agent-sendable audio/image resources, WhatsApp templates, and Instagram profile/post data Requires a Ninjo account. Sign in with your Ninjo credentials via OAuth when connecting. 95 tools reported — Publisher-reported; not verified by Pod. ## [RECOG](/mcp/recog) RECOG は、レター・投稿・バッジでメンバー同士が感謝と称賛を伝え合い、活躍を見える化してチームワークと従業員エンゲージメントを高める称賛プラットフォームです。このコネクタを使うと、Claude から RECOG のワークスペースをそのまま読み書きできます。 Claude ができること： ・感謝のレターを贈る。贈ったレター・受け取ったレターの閲覧、コメント・拍手・リアクションにも対応 ・スレッドへの称賛の投稿、スタンプでのリアクション、下書き・予約投稿の管理 ・トーク（チームチャット）のメッセージの閲覧・送信 ・メンバー・プロフィール・チーム・役職の検索・参照 ・ランキング・バッジ・ハッシュタグ・成長ヒストリーレポートの確認 「リリースを手伝ってくれた田中さんにお礼のレターを書いて」「今週の称賛投稿を要約して」「今月レターをいちばん受け取ったのは誰？」のように、自然な言葉で依頼できます。 Claude はあなた本人としてアクセスするため、閲覧・操作できる範囲はあなたの RECOG アカウントの権限と同じです。RECOG アカウントでサインインするだけで利用を開始できます。 41 tools reported — Publisher-reported; not verified by Pod. ## [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 — Publisher-reported; not verified by Pod. ## [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 — Publisher-reported; not verified by Pod. ## [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.

It carries both what the team knows — discoveries, fixes, failed approaches, product rules, and decisions — and what the team is doing now — questions, tasks, ownership, and active work areas — across sessions and machines. Git remains the source of truth for code; Vibsync keeps the context around the work. It works alongside existing agents rather than launching, routing, or controlling them. Bring your own model; Vibsync does not run inference. [ja] Vibsync は Claude Code・Cursor・Codex などのAIコーディングエージェントに、長期的なチームメモリと現在の作業状況を与えます。発見、修正方法、失敗したアプローチ、プロダクトルール、意思決定といった「チームが知っていること」に加え、質問、タスク、担当、作業中の領域といった「チームが今していること」を、セッションやマシンを越えて引き継ぎます。コードの正本はGitのまま、Vibsyncが作業の 周辺にあるコンテキストを保持します。既存のエージェントを起動・振り分け・制御するオーケストレーターではありません。利用者自身のモデルを使い、Vibsyncは推論を実行しません。 20 tools reported — Publisher-reported; not verified by Pod. ## [Superhuman Mail](/mcp/superhuman-mail) Connect Superhuman Mail to Claude, and build powerful workflows for email and calendar. Find anything in your inbox, draft replies that sound like you for every recipient, check read statuses, set reminders, schedule meetings, and send — all without leaving Claude. 19 tools reported — Publisher-reported; not verified by Pod. ## [Hero by Vivun](/mcp/hero-by-vivun) Meet Hero, your AI teammate for Sales. Hero can join your calls, write your follow-ups, research accounts, and help you keep every deal moving. This connector provides Claude read-only access to your Hero data so you can get Hero’s insights wherever you work best. What you can do in Claude with the Hero connector • Search meeting transcripts by keyword, meaning, date range, or workspace to pull the full transcript with per-speaker segments. • Find and read Hero-generated artifacts like call summaries, account research, saved notes, and uploaded files. • Browse and revisit your Hero conversation threads. • Get a list of your Workspaces (accounts and deals) to scope your work. Example prompts • “Summarize my calls with Acme this month, and draft a follow-up email.” • “Can you tell me what objections came up during yesterday’s demo with Hooli?” • “Pull the account research Hero wrote for Globex and turn it into a one-pager.” • “Find every call where pricing came up this quarter.” Security and Privacy • Sign in with secure OAuth: no passwords or API keys to manage. • Strictly read-only: Claude can retrieve your Hero data but cannot create, modify, or delete anything. • Scoped to your own account: Claude only sees data you already have access to in Hero • Requires a Hero account: get started at meethero.ai. 7 tools reported — Publisher-reported; not verified by Pod. ## For agents This page has a [Markdown](/mcp/tool/list-threads.md) and a [JSON](/mcp/tool/list-threads.json) twin. Pod is also queryable over MCP at `https://api.askpod.ai/mcp/read`.
