mcp-webcam
Use your Webcam to send live images to Claude Desktop (or other MCP Client).
Provides "capture" and "screenshot" tools to allow Claude to take a frame from the webcam or initiate taking a screenshot.
Provides a current view from the webcam resource too.
Installation
NPM Package is @llmindset/mcp-webcam.
Install a recent version of NodeJS for your platform, then add the following to the mcpServers section of your claude_desktop_config.json file:
"webcam": {
"command": "npx",
"args": [
"-y",
"@llmindset/mcp-webcam"
]
}
As long as you are using Claude Desktop 0.78 or greater, this will work on both Windows and MacOS.
Takes a single argument to set the Port for the embedded Express server.
Default port is 3333 (to avoid conflict if using with Inspector).
Usage
Start Claude Desktop, and connect to http://localhost:3333. You can then ask Claude to get the latest picture from my webcam, or Claude, take a look at what I'm holding or what colour top am i wearing?. You can "freeze" the current image and that will be returned to Claude rather than a live capture.
You can ask for Screenshots - navigate to the browser so that you can guide the capture area when the request comes in. Screenshots are automatically resized to be manageable for Claude (useful if you have a 4K Screen). The button is there to allow testing of your platform specific Screenshot UX - it doesn't do anything other than prepare you for a Claude intiated request. NB this does not not work on Safari as it requires human initiation.
MCP Sampling
Press the "What am I holding?" button To send a Sampling request to the Client, containing the Image and the question What is the User holding?.
[!TIP]Claude Desktop does not currently support Sampling. If you want a Client that can handle multi-modal sampling request, try https://github.com/evalstate/fast-agent/
Other notes
That's it really.
This MCP Server was built to demonstrate exposing a User Interface on an MCP Server, and serving live resources back to Claude Desktop.
This project might prove useful if you want to build a local, interactive MCP Server.
