# Klaviyo MCP connector The Klaviyo connector links your Klaviyo account to Claude, ChatGPT, Cursor, and any MCP client, so your team can ask about profiles, lists, segments, and tags in plain language and update them without opening Klaviyo. Source: https://elaichi.ai/connectors/klaviyo/ ## Facts | | | | --- | --- | | Application | Klaviyo | | Category | Marketing Automation | | AI tools | 336 | | Authentication | Connects with an API key | | Needs your own OAuth app | No | | MCP endpoint | https://api.elaichi.ai/mcp | | Works with | Claude, ChatGPT, Cursor, any MCP client, and the Elaichi Agent | | Tools advertised by name | No. 336 tools is past the 30-tool threshold, so clients use `search_tools` and `execute_tool` | ## What you can ask once Klaviyo is connected - Which Klaviyo segments grew most in the last 14 days - Create a Klaviyo list for winter sale early access - Show profiles in the VIP Klaviyo segment by region ## Connect Klaviyo in Elaichi This happens once for the organization, before any client is involved. 1. Open Connections, choose Add connection, and pick Klaviyo. 2. Optionally set Share with, then press Connect. 3. Paste a Klaviyo API key. One person generates a token in Klaviyo and pastes it once. Everyone else works through Share with, and never sees it. Credentials are vaulted and nobody, including the AI, reads them back. The connection becomes a toolbox immediately, so you can curate which Klaviyo tools are exposed, rename them, or freeze arguments before anyone points a client at it. ## Connect Klaviyo to Claude Endpoint: https://api.elaichi.ai/mcp 1. Open Customize, then Connectors. 2. Press Add. 3. Name it, paste the MCP server URL, then Continue. 4. Sign in and approve. On Team and Enterprise, an Owner adds it once. Everyone else turns it on for themselves. ## Connect Klaviyo to ChatGPT Endpoint: https://api.elaichi.ai/mcp 1. Open Plugins, then press the + button. 2. Name it and paste the endpoint into Server URL. 3. Leave Authentication on OAuth, then tick the risk acknowledgement. 4. Press Create, then sign in and approve. Works on the web today. The plugin directory lives at chatgpt.com/plugins. ## Connect Klaviyo to Cursor Endpoint: https://api.elaichi.ai/mcp 1. Open `~/.cursor/mcp.json`. 2. Add the endpoint under `mcpServers`. 3. Reload Cursor, then sign in and approve. Set up per machine, so repeat it on each computer you work from. ## Connect Klaviyo to any MCP client Endpoint: https://api.elaichi.ai/mcp 1. Add the endpoint as a remote MCP server. 2. Sign in and approve. The Elaichi Agent already has these tools, with nothing to set up. ## What the consent screen decides Only Read is granted by default, which is not enough to call a Klaviyo tool. Over MCP there is no trusted place to confirm a write in the moment, so the consent screen is the standing approval rather than a formality. Grant Read and Run tools. Think hard before granting Delete, which reaches into connected apps and cannot be undone. ## What teams do with Klaviyo through Elaichi ### Check which segments are ready for a send Marketing. Ask how many profiles sit in your VIP or lapsed-buyer segments before a campaign goes out, and pull the list of who is in each one. ### Build a new segment from a plain description Ecommerce. Describe the audience you want, such as people who joined a list this quarter, and have the segment created in Klaviyo with the right name and conditions. ### Look up a customer's Klaviyo profile Support. While handling a ticket, ask for the customer's profile by email and see which lists they are on, then add a new profile for a shopper who asked to hear from you. ### Keep lists and segments tidy Retention. Rename a list, retire segments nobody sends to anymore, and confirm what is left, all from one conversation. ### Tag lists and segments by campaign or region Operations. Create tags such as Spring launch or EMEA, attach them to the right lists and segments, and pull everything under a tag when the team needs it. ### Audit your audiences before a quarterly review Growth. Ask for every list and segment in the account with its tags, then have the agent summarize which audiences have grown and which are dormant. ## Frequently asked questions ### How do I connect Klaviyo to Claude? Connect Klaviyo in Elaichi first, then in Claude go to Customize, then Connectors, then Add, and paste https://api.elaichi.ai/mcp. Klaviyo connects with an API key: you paste a private key from your Klaviyo account settings into Elaichi and it is stored there, so there is no OAuth app to register and no client ID or secret to generate. Once that is done, Claude signs you in through Elaichi and Klaviyo is ready to use. ### Does Klaviyo work with ChatGPT and Cursor as well as Claude? Yes. Once Klaviyo is connected in Elaichi, the same endpoint, https://api.elaichi.ai/mcp, works in Claude, ChatGPT, Cursor, any other MCP client, and the Elaichi Agent. You connect Klaviyo once and every client you use picks it up. ### What can an AI agent actually do with my Klaviyo data? Through Elaichi, an agent can look up Klaviyo profiles, see which lists and segments they belong to, and create new profiles. It can create, rename, and remove lists and segments, count the profiles in each, and organize them with tags. Because Klaviyo exposes hundreds of actions, short concrete asks such as "how many profiles are in the VIP segment" work better than long paragraphs. ### Does connecting Klaviyo give the AI access to my whole account? The AI only gets what the Klaviyo API key you connected allows, and Klaviyo lets you scope a private key to specific areas and to read-only or full access. Elaichi then applies its own restrictions on top, so an admin can narrow what the agent can do further. Elaichi can only narrow access to Klaviyo, never widen it. ### Can my team share one Klaviyo connection? Yes. One person connects Klaviyo in Elaichi and shares the connection with a team, and nobody else ever sees or handles the API key. Each teammate still signs in to Elaichi as themselves, so every Klaviyo action in the audit log is tied to the person who asked for it. ### Can I stop an agent from deleting or changing things in Klaviyo? Yes. Restrictions in Elaichi work per action, so you can allow reading Klaviyo profiles, lists, and segments while blocking deletes or updates. A blocked action is never shown to Claude, ChatGPT, or any other client, so no prompt can reach it. ### What happens to a Klaviyo connection when someone leaves? When you offboard someone in Elaichi, their access to Klaviyo through every client ends at once. If they had shared a Klaviyo connection with their team, it keeps working for everyone else. If you want Klaviyo gone entirely, disconnecting it once in Elaichi removes it from Claude, ChatGPT, Cursor, and every other client together. ## All 336 Klaviyo tools Every tool below is callable through https://api.elaichi.ai/mcp once Klaviyo is connected, subject to the toolbox it is in and the restrictions on the caller. - **List all Klaviyo lists** (List).
