AI marketing platform with brand voice, campaign workflows and agents. Its MCP server gives other AI tools read access to brand voices, audiences, style guides and knowledge, and generates on-brand content; it needs a Business plan.
Jasper lists two plans: Pro at $59/month billed yearly or $69/month billed monthly, and Business with custom pricing. A free trial is offered. Checked 2026-10-17. source ↗
Jasper's hosted MCP server offers a subset of the API as tools: read-only access to brand voices, audiences, style guides, products, agents and the knowledge base, plus content generation, running agents and uploading temporary context. Connecting needs a Business plan with API access. source ↗
How Jasper connects to each AI platform: native connector or MCP, API through code the agent writes, browser control, or file upload.

Confirmed means both the tool's and the platform's official docs describe that route (links in the cell); IonBin has not tested every pairing. Not documented means it may work, but no official docs describe that route end to end. Checked Oct 17, 2026.
