Show HN: Product analytics (and evals) for agent sessions on your MCP

Armature is a new analytics tool designed to monitor and evaluate AI agent sessions within MCP-enabled applications. It provides visibility into user intent, agent reasoning, and session success rates to help developers identify failures and optimize agent performance.
Why it matters
Monitoring the 'black box' of AI agent reasoning is essential for businesses looking to deploy reliable AI-driven customer service and automation tools.
User sessions on your Claude Connector ChatGPT App or MCP live inside their AI client, not your UI. Armature captures and shows you what users ask, what agents think and how they use your product.
