Frequently asked questions
How do I get my Jasper API token?
You need a Jasper Business plan to access the API. Log in at app.jasper.ai, go to Settings → Dev Tools → API Tokens (direct link: app.jasper.ai/settings/dev-tools/tokens). Click Generate to create a new token. Copy it immediately and paste it below. Only users with Admin or Developer roles can manage API tokens. If you don't see the Dev Tools option, verify your account is on the Business plan or contact your Jasper account admin.
Can my AI agent write ad copy in my brand's voice?
Yes. Jasper's Brand Voice feature ensures all generated content matches your company's tone, vocabulary, and style guidelines. Your AI agent accesses your configured brand voices and applies them automatically — so copy for Google Ads, LinkedIn posts, and email campaigns all sound authentically like your brand.
What if I need variations for A/B testing?
Just tell your AI agent 'Generate 5 headline variations for my Google Ads campaign.' Jasper produces multiple distinct alternatives per request, each maintaining your brand voice but varying the angle, hook, or call-to-action — giving your growth team ready-to-test creative in seconds.
Is the Jasper Business plan required?
Yes. API access is exclusive to the Jasper Business plan. If you're currently on Creator or Teams, you'll need to upgrade. Contact the Jasper sales team through jasper.ai to discuss Enterprise pricing — most marketing teams find the ROI justifies the investment within the first month of automated content production.
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 Jasper MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
