FAQ

What are the most reliable utility MCP tools right now?

As of the latest check, Glimind tracks 61 utility AI agent (MCP) tools, of which 43 are healthy right now. The table below ranks them live-first by real-time reliability. Glimind rates each neutrally (0–100) from safe liveness probes plus privacy-clean real-usage outcomes — see each tool's live page for its current score and a working alternative if it's down.

How does Glimind rank utility tools?

Ranked live-first by current verdict (healthy → degraded → down), then by the neutral reliability score. Glimind sells no tools, so the ranking is unconflicted.

What if a utility tool I need is down?

Every tool here links to its live alternatives — capability-matched substitutes that are healthy now. Or query https://glimind.com/v1/alternatives/{toolId}.
