What the code does

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.

Runs an external command packages/agent-benchmark/src/agents/claude.ts:17, packages/mcp/src/cli-runner.ts:59

  const proc = Bun.spawn(["claude", ...buildClaudeArgs(model, prompt)], {

Executes code built at runtime packages/optimizer/src/inventory.ts:141

      const fn = new Function(`return (${fnSrc})`)() as (k: string[], m: number) => unknown;

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

One Shot UI — questions

Answers built from our own checks of this server.

Why is there no uptime for One Shot UI?

One Shot UI runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package one-shot-ui was installed 66 times last week.

How do I connect One Shot UI?

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 runs locally, so the command pulls one-shot-ui straight from npm; nothing to host, nothing to sign up for.

How many people use One Shot UI?

The npm package one-shot-ui was installed 66 times in the last week. Week over week that is -34%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is One Shot UI open source?

Yes — it is published under the MIT licence, written in TypeScript and 5 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
