Subtext MCP¶

Agent-native session replay from Fullstory. Captures production sessions of your application and connects them to your coding agent — Claude Code, Cursor, Codex — so it can debug issues, analyze user behavior, and improve UX from real session data.

Why It Matters for Operators¶

For operators running SaaS products or web applications, Subtext MCP bridges the gap between production issues and AI-driven debugging:

Agent-Driven Debugging: Your AI agent replays the exact user session where a bug occurred
UX Analysis: AI reviews real user sessions to identify friction points
Support Triage: Connect support tickets to session replays for faster resolution
No Context Switching: Debug production issues without leaving your coding agent
