Omnisend MCP connector

The Omnisend connector lets Claude, ChatGPT, Cursor, or any MCP client read and update your Omnisend contacts, tags, products, categories, and campaigns, with each person signed in as themselves and every change recorded in an audit log.

  • How it connects. Connects with an API key. The credential goes into a vault nobody reads back.

  • One address. https://api.elaichi.ai/mcp, the same for every user.

  • Their own access. An agent never gets more than the person it acts for.

How to connect

How to connect Omnisend to Claude, ChatGPT or Cursor

Two steps, about a minute.

1

In Elaichi

Connect Omnisend once

  1. Open Connections, choose Add connection, and pick Omnisend.

  2. Optionally set Share with to give a team access, then press Connect.

  3. Paste an Omnisend API key. One person generates a token in Omnisend and pastes it once. Everyone else works through Share with, and never sees it.

The credential is vaulted. Nobody reads it back, not even the AI.

FAQ

Frequently asked questions

How do I connect Omnisend to Claude?

First connect Omnisend in Elaichi by pasting the API key from your Omnisend account settings. There is no OAuth application to register and no client ID or secret to generate. Then in Claude open Customize, then Connectors, then Add, and paste https://api.elaichi.ai/mcp. Sign in to Elaichi when prompted and Omnisend is available in your conversation.

Does Omnisend work with ChatGPT and Cursor as well as Claude?

Yes. Once Omnisend 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 Omnisend once and every client picks it up.

What can an AI agent actually do with my Omnisend data?

It can look up and update contacts in Omnisend, add or remove tags, update many contacts at once, load new contacts as a batch, add and edit products and product categories, and list or set up campaigns. Because Omnisend has a lot of actions available, short concrete asks work best, such as "tag everyone from the Boston store as VIP" rather than a long paragraph.

Does connecting Omnisend give the AI everything in my account?

No. The agent works inside the access of the Omnisend account whose API key was used, and in Elaichi each person signs in as themselves, so every action is tied to a named person. Elaichi can narrow what the AI is allowed to do with Omnisend, for example read-only or contacts only, but it can never widen access beyond what the account already has.

Can my team share one Omnisend connection?

Yes. One person connects Omnisend 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 the audit log names who updated a contact or created a campaign in Omnisend.

Can I stop an agent from deleting or changing things in Omnisend?

Yes. Restrictions in Elaichi apply per action, so you can allow reading Omnisend contacts and campaigns while blocking deletes or updates to products and categories. A blocked action is never shown to Claude, ChatGPT, or any other client, so no prompt can reach it.

What happens to an Omnisend connection when someone leaves?

Offboarding that person in Elaichi ends their access to Omnisend through every client at once. If they set up a shared Omnisend connection, it keeps working for everyone else on the team. Disconnecting Omnisend once in Elaichi removes it from Claude, ChatGPT, Cursor, and every other client at the same time.
