Omnisend MCP lets you connect your Omnisend account to AI tools so you can ask natural-language questions about your campaigns, automations, subscribers, and performance.
The easiest way to use Omnisend with AI is through the Omnisend App in ChatGPT, which is now available in the ChatGPT app store. You can connect your Omnisend account directly from ChatGPT and start asking questions without any custom setup. The official Claude connector is coming soon.
If you use another AI tool that supports MCP, you may also be able to connect Omnisend manually using the Omnisend MCP server.
What Is MCP?
MCP stands for Model Context Protocol. In simple terms, MCP is a standard way for AI tools to connect to external apps, data, and services. An MCP server acts like a secure bridge between an AI tool and a platform like Omnisend.
For Omnisend, this means an AI tool can securely access your Omnisend data and help answer questions such as:
How did my campaigns perform last month?
Which automations generated the most revenue?
Are my subscribers growing or declining?
What should I improve based on recent performance?
MCP is an open standard used by many AI tools. That means Omnisend MCP is not limited to a single AI assistant. In general, any AI tool that supports MCP can connect to Omnisend MCP.
What Data Can AI Tools Access?
When you connect Omnisend through MCP, the AI tool can access the Omnisend data needed to answer your questions or complete your request.
This may include campaigns, automations, analytics, contacts, forms, segments, and related performance data. You will be asked to authorize access during the connection process. You can disconnect access later from the AI tool or app settings.
Option 1: Connect Omnisend in ChatGPT
This is the recommended option for most users.
Omnisend is now available as an app in ChatGPT. Once connected, you can ask questions about your Omnisend data directly inside ChatGPT, without switching between platforms.
Option 2: Connect Omnisend to Claude with a Custom Connector
The official Omnisend connector for Claude is coming soon. In the meantime, you can connect Omnisend manually by adding it as a custom connector in Claude.
In Claude, click Customize in the left menu, then go to Connectors. Click +, then choose Add custom connector. Enter Omnisend as the name and use this URL:
Click Add, select the Omnisend connector, then click Connect. You’ll be redirected to the Omnisend OAuth flow, where you can log in to your Omnisend account and approve the requested permissions.
Once connected, you can start a new conversation in Claude and ask something that requires Omnisend context, such as a question about your recent campaign or automation performance, to confirm the connection is working.
Option 3: Advanced MCP Connections
For users who are comfortable with more advanced AI tools such as Claude Code, OpenAI Codex, and Cursor.
Connect Omnisend MCP in Claude Code
Open your terminal and run:
claude mcp add --scope user --transport http omnisend https://mcp.omnisend.com/mcp
Then open Claude Code and use the /mcp command to check the connection and complete authentication if prompted.
Claude Code supports adding remote MCP servers over HTTP, and the --scope user option makes the connection available across your Claude Code projects.
Connect Omnisend to OpenAI Codex
OpenAI Codex also supports MCP servers. This can be useful if you use Codex for development work and want it to access Omnisend through MCP.
Codex supports MCP in the CLI and IDE extension, including remote HTTP MCP servers and OAuth authentication.
Add Omnisend MCP to Codex
Open your Codex configuration file:
~/.codex/config.toml
Add this section:
[mcp_servers.omnisend]
url = "https://mcp.omnisend.com/mcp"
Then run:
codex mcp login omnisend
Follow the browser authentication flow to connect your Omnisend account. Codex stores the MCP configuration in config.toml, and the CLI and IDE extension share this configuration. Once Omnisend MCP is added, you should be able to use it from supported Codex environments.
Option 4: Connect Omnisend to Other MCP-Compatible Tools
Omnisend MCP can also work with other AI tools that support MCP.
Use the Omnisend MCP server URL:
The exact setup depends on the AI tool you are using. Look for a setting called one of the following:
MCP
MCP servers
Connectors
Tools
Integrations
Remote MCP server
When asked for the server URL, use:
If the tool supports OAuth, you should be able to sign in to your Omnisend account during setup. For technical details, please refer to the Omnisend MCP Server documentation.
Troubleshooting Connection
If the connection does not work:
Make sure you are logged in to the correct Omnisend account.
Refresh or restart the AI tool.
Disconnect and reconnect Omnisend.
Check whether your AI tool supports remote MCP servers over HTTP.
If using Claude Code or Codex, confirm that authentication completed successfully.
FAQ
Which MCP option should I use?
For most users, use the Omnisend App in ChatGPT. It is the easiest setup and does not require technical configuration.
Use a custom MCP setup only if:
You are using an AI tool that already supports MCP
You are comfortable configuring external tools
Your team wants to use Omnisend data inside developer-focused tools like Claude Code or Codex
If you are not sure which option to choose, you can start with ChatGPT.
Can I connect Omnisend MCP to Gemini?
Not currently. Gemini’s web app does not support MCP connectors, so you can’t connect Omnisend MCP directly to Gemini in the browser, as you can with ChatGPT or Claude (coming soon).
If Gemini adds MCP support in the future, Omnisend MCP should be able to connect using the standard MCP server URL:
For ChatGPT connection issues, you can contact Omnisend support through the in-app chat or at [email protected].
