What we checked (2026-10-17)
Jasper MCP is hosted at mcp.jasper.ai and signs in with OAuth, or with a Jasper API key. Its tools include get-jasper-brand-voices, get-jasper-audiences, get-jasper-style-guides, search-knowledge-base and generate-content. If the calling agent doesn’t name a brand voice or style guide, generate-content falls back to your workspace defaults.
Plans. Jasper Pro is $59 a month per seat billed yearly and includes 2 brand voices. API access is listed on the Business plan, which is priced on request. The MCP page doesn’t state a plan for OAuth connections, so check with Jasper.
Grammarly has no official MCP server, so the clarity check is a manual pass in Grammarly. Its free tier is $0.
HubSpot remote MCP reads and writes CRM records. We didn’t confirm that it can create marketing email assets, so treat this step as storing the copy, and build the email in HubSpot yourself.
