Reviewer Notes

FullStory has a documented REST API and free tier, which helps discoverability, but lacks MCP server and llms.txt integration. Account creation requires human intervention (email verification, no programmatic signup). The API is well-structured for analytics queries and session data retrieval, supporting agent use cases around data extraction. However, the tool is primarily designed for human dashboards rather than agent-native workflows, and reliability depends on external FullStory infrastructure without strong rate-limit documentation. The pricing model is adoption-heavy, making free tier limited for autonomous agent operation at scale.
