State of MCP Reliability

A neutral, cross-ecosystem snapshot of how AI agent tools are performing right now — kept current by safe liveness probing plus privacy-clean real-usage outcomes. Glimind sells no tools, so these ratings are unconflicted. Updated 2026-07-02.

Why this matters

Tool calls are where agentic workflows fail most — and failures compound: five chained calls at 80% each finish only ~33% of the time. Knowing which tools work before you call them (and routing around the ones that don't) is the difference between a demo and something you can run in production. That's what Glimind does on every call — see how it works.
