measure

measure_voice_quality

Measure the quality of a voice/VoIP path to a destination and return the estimated MOS (ITU-T G.107 E-model) plus live network metrics (RTT, jitter, packet loss). Useful before routing or starting a voice-agent call. The MOS is an objective estimate, not a perceptual measurement.

Voice Quality API — questions

Answers built from our own checks of this server.

What can Voice Quality API do?

It exposes 1 tools, read directly from the server on our last check. Among them: measure_voice_quality. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Voice Quality API working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 11 of 91 checks got a reply (12.1%), average response time 332 ms. The bar chart above shows every period we have measured.

How do I connect Voice Quality API?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Voice Quality API need an API key?

No. Voice Quality API completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 1 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Voice Quality API?

It answers our handshake in 332 ms on average, which is faster than 46% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is Voice Quality API open source?

We cannot say either way: written in TypeScript and 0 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
