Which app do you use?
Pick your app above. We remember it, so next time the button says “Install in …”.
Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

Common questions
Is Hostbeam safe?
It passed 1 of 1 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 –, and the latest version (0.1.4) reached the registry 29 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?

Hostbeam MCP server
Hostbeam sends a screenshot from your Mac or your iPhone to a server over SSH and puts the remote path on your clipboard, so you can paste it to a coding agent running there.
This MCP server runs on that server, next to the agent. The agent can ask for the screenshot you just beamed and read it, without you pasting the path.
Install
On the server your agent runs on, not on your Mac or your phone. Node 18 or later.
For Claude Code:
claude mcp add -s user hostbeam -- npx -y @hostbeam/mcp-s user makes it available in every project on that server.
For Codex:
codex mcp add hostbeam -- npx -y @hostbeam/mcpFor other MCP clients, in their JSON config:
{"mcpServers": { "hostbeam": { "command": "npx", "args": ["-y", "@hostbeam/mcp"] } } }
If the server can't reach npm, copy hostbeam-mcp.mjs to it and run that instead. It has no dependencies.
claude mcp add -s user hostbeam -- node /path/to/hostbeam-mcp.mjsHostbeam beams to /tmp/hostbeam unless you changed the folder for that host. If you did, give the server the same folder: -e HOSTBEAM_DIR=/your/folder for Claude Code, --env HOSTBEAM_DIR=/your/folder for Codex, or "env": { "HOSTBEAM_DIR": "/your/folder" } in JSON.
Tools
- `latest_screenshot` returns the most recent beam as images, with how long ago it arrived. If you beamed several files at once, it returns all of them, up to six, and names the rest.
- `list_screenshots` lists recent beams with file names, sizes and times. No image data.
- `read_screenshot` returns one file by name.
What it reads
Only files Hostbeam delivered: names starting with hostbeam- with an image extension, in that one folder. It doesn't look in subfolders, and it refuses a name with a path in it. It never writes, moves or deletes anything.
It skips symlinks, and it won't read a folder that belongs to another user or that any user can write to, because a file there may not be one you beamed.
JPEG, PNG, GIF and WebP come back as images, up to 3.75 MB each. Other formats and larger files come back as a path instead: models only accept those four formats, and model APIs refuse bigger images. When a beam holds several files, latest_screenshot includes images up to 7.5 MB in total and names the rest.
Check it by hand
It speaks newline-delimited JSON-RPC on stdin and stdout:
printf '%s\n' \'{"jsonrpc":"2.0","id":1,"method":"initialize","params":{}}' \ '{"jsonrpc":"2.0","id":2,"method":"tools/call","params":{"name":"list_screenshots"}}' \ | npx -y @hostbeam/mcp
