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 native/MenuBarApp.swift:176, [пакет] native/MenuBarApp.swift:176

        let process = Process()

Runs an external command src/adminRuntime.ts:182, src/processRunner.ts:23

  const result = spawnSync(lsof, ["-nP", `-iTCP:${port}`, "-sTCP:LISTEN", "-t"], { encoding: "utf8" });

Builds a file path from a variable src/menuBar.ts:121

  const builtApp = path.join(buildRoot, appName);

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.

Onepassword Agent MCP — questions

Answers built from our own checks of this server.

Why is there no uptime for Onepassword Agent MCP?

Onepassword Agent MCP 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 onepassword-agent-mcp was installed 112 times last week.

How do I connect Onepassword Agent MCP?

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 onepassword-agent-mcp straight from npm; nothing to host, nothing to sign up for.

How many people use Onepassword Agent MCP?

The npm package onepassword-agent-mcp was installed 112 times in the last week. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is Onepassword Agent MCP open source?

Yes — it is published under the MIT licence, written in TypeScript and 0 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.
