Yaver MCP Server

by kivanccakmak Your server? Claim it
local only

Yaver runs on your own machine — the client starts it, so there is no endpoint to ping. Last commit 11 Oct 2026.

Phone-first local dev MCP for Claude Code and Codex: install Yaver, pair mobile, run, build, deploy.

Evidence

Things with no honest explanation: a promise that contradicts the code, code that runs at install time while hiding what it does, data leaving the machine.

Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

We found things in this code

Code changes quietly between releases, and nobody reads the diff of a dependency. We do, on every release — watch Yaver and you get told the day something new turns up.

Yaver — questions

Answers built from our own checks of this server.

Why is there no uptime for Yaver?
Yaver runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone.
Is Yaver open source?
We cannot say either way: written in Go, 4 stars on GitHub and 3 open issues, but we could not determine the licence, and without one the code is not open source by default.
