Ease of use and autonomous level
Automation
How easy it is for a team to reach useful outcomes, and how much work the product can perform autonomously after setup.
SparkToro
MCP can create reports and retrieve sections conversationally, but usage remains quota/credit governed and does not publish or execute campaigns.
MCP documentation lists create_report, status, report listing, and section tools; the API page shows custom-agent workflows. https://sparktoro.com/mcp/docs
Zutrix
MCP setup is three steps and skills chain tools into workflows, though publishing still requires human sign-off.
