Common questions

Is localhost app safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed today, and the latest version (0.2.0) reached the registry 10 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

@getlocalhost/cli

Connects your coding agents to localhost mcp, the MCP server of localhost app, from a terminal:

npx @getlocalhost/cli mcp install

It adds a server named localhost to Claude Code, Claude Desktop, Cursor and Codex, whichever are on this computer, and installs the localhost-mcp skill where each agent reads skills. The server runs the localhost command that comes with the app, so the app must be installed: without it, this prints how to install it for your OS and changes nothing.

It writes what Settings → Agents in the app writes, and the app shows these agents as connected:

Agent	MCP server added to	Skill installed in
Claude Code	`~/.claude.json`, through `claude mcp add-json --scope user` when `claude` is installed	`~/.claude/skills/localhost-mcp/`
Claude Desktop (macOS, Windows)	`claude_desktop_config.json` in Claude's folder (`~/Library/Application Support/Claude`, `%APPDATA%\Claude`)	none: it has no skills folder
Cursor	`~/.cursor/mcp.json`	`~/.cursor/skills/localhost-mcp/`, unless Claude Code's or Codex's folder has it: Cursor reads those too
Codex	`~/.codex/config.toml`	`~/.agents/skills/localhost-mcp/`

Only its own entries. Every other server and setting in the file stays as it was, comments and order included. A file it can't read is reported and left alone.
A backup first, in the agent-backups folder of localhost's data folder, before it first changes a file.
Running it again changes nothing.

Commands

npx @getlocalhost/cli mcp install     # add the server and the skill

npx @getlocalhost/cli mcp uninstall # remove them, and nothing else npx @getlocalhost/cli mcp status # where each agent stands npx @getlocalhost/cli mcp serve # run the server, for an MCP client's configuration

Option
`--client`	`claude-code`, `claude-desktop`, `cursor` or `codex`; `claude` for both Claude apps. Repeat it, or separate with commas, for more than one. Without it: every agent found on this computer.
`--read-only`	For `mcp install` and `mcp serve`. The server runs `localhost mcp --read-only`, without the tools that add, edit or remove Projects and Services. Needs a localhost app that has it (0.4.0 or later). Installing again without it keeps a read-only server read-only.
`--dry-run`	Prints what would change, as a diff, and changes nothing.

Then start a new Claude Code session, quit and reopen Claude Desktop, check Cursor Settings → MCP, or restart Codex.

Any MCP client

mcp serve is the server itself, for any client that starts MCP servers over stdio:

"mcpServers": { "localhost": { "command": "npx", "args": ["-y", "@getlocalhost/cli", "mcp", "serve"] } } }

It finds the app's localhost command as mcp install does and runs localhost mcp with the client's stdin and stdout, passing on Ctrl-C and other signals and exiting as the server does. mcp serve --read-only runs localhost mcp --read-only. It writes nothing to stdout itself, since that is the client's channel: without the app, or with an app whose command doesn't run, it says why on stderr and exits with 1. claude mcp add --scope user localhost -- npx -y @getlocalhost/cli mcp serve and codex mcp add localhost -- npx -y @getlocalhost/cli mcp serve add it from a terminal.

More in the MCP docs. Node 18 or later; no dependencies.

Development

cd packages/cli

npm test node bin/getlocalhost.js mcp status

The JSON and TOML editors are the same as the core's (core/localhost-core/src/agents/), and their tests too: change both together. npm pack copies the skill from skills/localhost-mcp into the package.
