How to Use the SmartLead MCP in Pydantic AI

Q: Can the Pydantic AI list all my SmartLead campaigns?

Yes. The server exposes listcampaigns. Your agent calls this tool, and because of the type safety, you get a predictable data structure containing all campaign details.

Q: If I use Pydantic AI, how do I check performance?

You call getcampaignanalytics. This provides concrete metrics. The benefit is that the response is always validated against your schema, so you can trust the numbers immediately.

Q: Does the SmartLead MCP Server support multiple sending accounts?

It does. Use listemailaccounts to see all available credentials managed by SmartLead. This ensures that when your agent runs campaigns, it has reliable access to rotation details.

Manage Outreach Campaigns via MCP Server

Your agent needs to know if a campaign is running or not. Use `get_campaign` to grab full details, or check performance with `get_campaign_analytics`. The Pydantic AI framework guarantees that the data structure returned by SmartLead is exactly what you expect. You can also pause things for review using `pause_campaign`, ensuring a clean and type-safe execution flow.

Add Leads and View Target Lists

Feeding new contacts into SmartLead is simple. Your agent executes `add_lead` to input data, and the Pydantic validation ensures the payload structure is correct before sending it. Need a list of targets? Use `list_leads`. The response will always validate against your defined schema, so you never get corrupted or unexpected fields.

Monitor SmartLead Account Status

Managing credentials is crucial for high-volume outreach. Call `list_email_accounts` to see all available sending accounts in SmartLead. Additionally, use `list_campaigns` to get a structured list of every active campaign. The type safety means you know exactly what kind of data structure your agent is working with.
