Frequently asked questions
How do I get a Loops API key?
Log in to your Loops account, go to Settings → API, and generate a new API key. Ensure it has the necessary permissions. Then provide it when prompted by the MCP server setup.
What operations are supported by this MCP server?
The server supports: testing API key validity, finding/creating/updating/deleting contacts, listing mailing lists, sending events to trigger email journeys, sending transactional emails, listing sent transactional emails, and checking contact suppression status.
What is the difference between mailing lists and transactional emails in Loops?
Mailing lists are used for marketing campaigns and automated email journeys. Transactional emails are one-off, triggered messages like receipts, password resets, or order confirmations. Both are supported by this MCP server.
How can I check if an email is suppressed in Loops?
Use the 'get_contact_suppression' tool provided by this MCP server. Simply ask the AI to check the suppression status for any email address, and it will tell you if that email is currently suppressed from receiving emails.
How does Pydantic AI discover MCP tools?
Create an MCPServerHTTP instance with the server URL. Pydantic AI connects, discovers all tools, and generates typed Python interfaces automatically.
Does Pydantic AI validate MCP tool responses?
Yes. When you define result types as Pydantic models, every tool response is validated against the schema. Invalid data raises a clear error instead of silently corrupting your pipeline.
Can I switch LLM providers without changing MCP code?
Absolutely. Pydantic AI abstracts the model layer. your Loops MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
