URL Opener

MCPOpen SourceMIT18.0

by worldnine • Testing & QA

A tiny MCP server that opens provided URLs in the system default browser for use by MCP-compatible clients.

Example Use Cases

1
Open a handled URL in the local default browser to preview content or confirm behavior.
2
A simple MCP-accessible tool to validate or test links discovered while processing other servers' outputs.
3
Delegate link-opening to the host environment (e.g., Claude Desktop) instead of trying to render remote content themselves.

Description

This MCP server accepts URL inputs and launches them in the user's default web browser, making it easy for agents (such as Claude Desktop) to preview or validate links. It's extremely simple to run via npx or as a node executable and integrates over stdio using the MCP protocol. The server normalizes URLs by prepending https:// when no scheme is provided and returns success or error messages for each request. Its simplicity makes it useful for testing, debugging, or giving agents a safe way to open links externally.
