Show HN: Armature Adds Product Analytics and Evals to Your MCP Server, Free Up to 1,000 Sessions
Armature (40 points) captures agent sessions running against your MCP server across Claude, ChatGPT and other clients, surfacing user intent, agent reasoning, every tool call and response, and success scores — then groups sessions by use case ranked by volume and success rate, and clusters failures, loops and dead ends by root cause. The YC-backed free tier covers 1,000 credits monthly (1,000 sessions, 100 eval runs, or a mix), with $50 per additional 1,000 credits and enterprise plans adding SSO, audit logs and custom retention. It targets a real gap: MCP server authors currently ship tools with almost no visibility into how agents actually use them.
