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

Armature is a product analytics platform that captures and analyzes user sessions within AI agents (Claude, ChatGPT) and Model Context Protocol (MCP) integrations, showing user intent, agent reasoning, and task completion. The tool helps developers identify top use cases, spot issues causing failures, and replay sessions for debugging, while automatically redacting sensitive data and PII before storage.
