## MCP tools (3)

### `latest_screenshot` (~99 tokens)

Latest screenshot

Read the latest beam: every screenshot the user sent to this host with Hostbeam in one gesture (several, if they beamed several), with how long ago it arrived. Use this when they refer to a screenshot, to something being broken on screen, or ask you to look at what they are seeing. If it does not match what they describe, or arrived long before they asked, say so rather than assuming it is what they meant.

### `list_screenshots` (~65 tokens)

List screenshots

List the screenshots the user has beamed to this host, grouped by beam, newest first, with sizes and how long ago. Metadata only — no image data — so it is cheap to call before deciding which to read.

Input parameters:

- `limit` (integer): Default 10.

### `read_screenshot` (~58 tokens)

Read screenshot

Read one specific beamed screenshot by its file name, as listed by list_screenshots.

Input parameters:

- `name` (string, required): A file name exactly as list_screenshots gives it, such as hostbeam-1788875278869.png.

## Common questions

### What is the Hostbeam MCP server?

Hostbeam is an MCP server listed in the public MCP registry as app.hostbeam/mcp. Lets a coding agent read the screenshots you beam to its server with Hostbeam. This page covers its npm package (@hostbeam/mcp).

### Is the Hostbeam MCP server safe to use?

Hostbeam scores 80 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 2 October 2026. It declares no install or post-install scripts. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Hostbeam MCP server expose?

Hostbeam exposes 3 tools: latest_screenshot, list_screenshots, read_screenshot. Their descriptions and schemas cost roughly 222 tokens of context every time the server is loaded.

### Is the Hostbeam MCP server still maintained?

Hostbeam is still listed as active in the MCP registry. We last reached this channel on 2 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the Hostbeam MCP server under?

Hostbeam declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
