    "description": "This specification describes the **KlickTipp MCP Server**.\n\nIt is intended for developers and integrators who want AI assistants — Claude, ChatGPT, or any other MCP-capable client — to interact with KlickTipp through the **Model Context Protocol (MCP)** instead of raw HTTP calls: to manage newsletters, contacts, tags, custom fields and opt-in processes.\n\n**What this document is for:** it is a reference, not a live console — it shows what the KlickTipp MCP server can do, so you can see what's possible before connecting anything. You do not need a KlickTipp account, an OAuth sign-in, or a running MCP client just to browse it. It is a separate documentation area from the classic KlickTipp Management API. This document is meant to show the current functional scope of the server, not a fixed contract: tools, schemas and everything else here are subject to change.\n\n> **Current tool list & source:** [`agent-plugins` repository on GitHub](https://github.com/klicktipp/agent-plugins). Tools shown in this document are subject to change — the repository always reflects the current state. Once you are connected, any MCP client can also fetch the same tool list live from the server itself with the standard MCP tools/list call.\n\n---\n\n## MCP Server\n\nThe KlickTipp MCP server lets AI assistants — Claude, ChatGPT, or any other MCP-capable client — interact with a KlickTipp account through the Model Context Protocol (MCP), instead of raw HTTP calls. The endpoint for the production environment:\n\n| | |\n|---|---|\n| **URL** | `https://mcp.klicktipp.com/mcp` |\n| **Authentication** | Managed OAuth 2.0 (no API key, no local server, no `.env` file needed) |\n| **Requirement** | A KlickTipp **Deluxe** or **Enterprise** subscription with permission to log in to the account in question |\n\n> **Good to know:** this MCP Server uses a KlickTipp managed OAuth 2.0, not the Management API's session cookie or key-based authentication.\n\n---\n\n## Getting Started\n\nA rough guide to connecting any MCP-capable client:\n\n1. **Add the server**\n   In your MCP client's connector/integration settings, add a new remote MCP server pointing to this URL:\n     ```\n     https://mcp.klicktipp.com/mcp\n     ```\n2. **Complete the OAuth sign-in**\n   Your client redirects you to sign in with your KlickTipp credentials. Every tool call afterwards is made as that signed-in user, against the account they are permitted to access.\n\n3. **Call tools**\n   Once connected, call the tools listed in this document by name.\n\nThe exact setup steps differ a little by client. Step-by-step instructions for Claude and for ChatGPT specifically are in the [MCP server guide](https://developers.klicktipp.com/guides/mcp-server).\n\n> Before OAuth sign-in completes, calls are expected to return `401 Unauthorized`. That is not a configuration error — it is the normal state before login. If a sign-in was interrupted or not approved, simply repeat the connection process.\n\n---\n\n## Tool Catalog\n\nThe KlickTipp MCP server exposes tools that your MCP client can call to interact with a KlickTipp account — to manage newsletters, contacts, tags, custom fields and opt-in processes. Tools are grouped by category in the sidebar.\n\n---\n\n## Security Behaviour\n\nThe MCP server is deliberately designed so an AI assistant can search and read broadly, while critical and irreversible actions stay with a human:\n\n- **Sending a newsletter always needs a separate human confirmation inside KlickTipp.** The dispatch tool only validates the newsletter and returns a short-lived, single-use confirmation link; the actual send is always confirmed separately by the logged-in user in the KlickTipp app.\n- **Some destructive actions are available over MCP** — for example, deleting a tag, a custom field or an opt-in process. These are irreversible and affect the account directly: use them deliberately, and confirm with a human before calling them.\n- **Tools that can start or change campaigns, autoresponders or automations as a side effect (assigning or removing a tag,   subscribing or unsubscribing a contact) require an explicit `approval` field in the request**, so a calling client can prompt a human before those effects happen.\n\n---\n\n## Error Handling\n\nA failed tool call is handled by the client and returned as a clear, human-readable error — for example when authentication hasn't completed yet, or an unknown tool is called — rather than a raw HTTP response.\n\n---\n\n## Plugin & Further Use Cases\n\nFor Claude and Codex, KlickTipp also offers a combined **plugin package** that bundles the MCP server with matching **skills**. The skills train the assistant to use the tools documented here effectively, with a focus on the structure of the email editor, reporting, and messaging workflows (newsletters and split tests).\n\nFor setup instructions per platform (Claude Desktop, ChatGPT, and other agentic tools), see the [MCP server plugins guide](https://developers.klicktipp.com/guides/mcp-server-plugins).\n",

A field that opt-in forms, automations or other entities still use is refused as well, and the refusal names them, so nothing that reads the field breaks silently. The placeholder of a deleted field renders an empty value wherever content still carries it.",

An empty stored sender or reply-to is reported as the account's own address; senderIdentity reports its current status and concrete choices. The body is not part of this answer -- it is get-opt-in-confirmation-email-content. A confirmation email is not a drag-and-drop document, so the block tools do not accept it; the answer carries bodyIsEditable false for that reason and an editUrl into the KlickTipp editor. Single opt-in processes still have this email stored; it is simply not sent. Change it with update-opt-in-confirmation-email.",

Only while the delivery status says canBeCancelled: once a dispatch is far enough along it cannot be called off, and the refusal says so rather than pretending. What already went out stays out -- this stops what has not been sent yet, it does not recall mail. The newsletter itself, its content and its audience are untouched; only the dispatch is undone, and activating it again is prepare-newsletter-dispatch.

It checks permission, published content, audience and sender, estimates the recipients and returns a short-lived single-use confirmation URL bound to that exact summary. Only the logged-in user, by opening the URL in KlickTipp and confirming there, hands the newsletter over -- that reaches real recipients and cannot be taken back. Content that was changed but not published is refused; publish it first with publish-newsletter-email-content. The mode has to be given explicitly; a scheduled moment carries its own UTC offset. If a bound value changes or the URL expires, a new preparation is needed. The dispatch state is read through get-newsletter with deliveryStatus.",

The pictures come from the editor's own icon sets, which this server cannot enumerate, so one reused from here is the only src that stays inside the set a person picked in the editor -- which is why this read precedes add-email-editor-social-links and update-email-editor-social-links. A src from anywhere else resolves to nothing, and that hole in the row stays invisible until the mail is out at every recipient. An account's own picture works as an icon too and is found with list-email-editor-images. An empty answer means this email carries no icon yet; then the library is the remaining source, and a social block placed once in the editor is the way on.",

Replaces the stored draft entirely, has no undo, and does not publish: the dispatch content changes only through publish-newsletter-email-content, named in nextAction. Bound to the content revision of the preceding read. A newsletter that already has content is refused on the first call with a list of what it holds; a second call with replaceExistingContent set to true converts. Non-HTML blocks (add-ons, decisions, AI blocks) are rendered or dropped; the warnings record what it cost. The body has to carry the %User:Signature%placeholder or spell out postal details and unsubscribe link, else it is refused. Returns content status, new revision and editor URL.",

The three lists are the same three filters this tool takes, so an answer says how to narrow the next call: a category, collection or tag this tool ANSWERED with is always one it accepts back. All three are free text out of the catalogue's own vocabulary, and a value it does not know matches nothing rather than being refused. Paged: twelve per page by default, with total and nextPage. A host that renders MCP Apps shows the designs as pictures; without one, offer the names and let the user pick, because a template is a layout and its name does not describe it.

The typography of a text block is not here: its font, size, line height and colour live in the markup of that block, so they are changed with update-email-editor-text, and the size an image is shown at belongs to the image.
