Two ways to install an MCP server: the .mcpb one-click bundle for Claude Desktop, or the remote MCP URL for Cursor, Codex, ChatGPT, and Claude Code. As of May 2026 we recommend the remote URL for most users — this page explains why and when the .mcpb installer still wins.

.mcpb file is still supported as a one-click stdio installer for Claude Desktop, but pasted API keys can't be rotated without reinstalling. See remote URL setup →Just like .dmg files on Mac or .exe files on Windows

MCPBundles .mcpb files are special—they don't run a local server. Instead, they connect to our cloud infrastructure where your bundles are hosted with automatic updates, centralized credentials, and multi-provider tool aggregation.
Four simple steps to get started
You'll need Claude Desktop installed on your computer. Download it from claude.ai/download
Go to your MCPBundles Settings and copy your API key. You'll need this to connect to your bundles.
Visit any bundle page, click "Download .mcpb", and save the file to your computer.
Double-click the .mcpb file. Claude Desktop will automatically install it and prompt you to enter your API key.
Open Claude Desktop and your bundle's tools are ready! Ask Claude what tools it has access to.
The MCP URL is now the recommended path — .mcpb remains as a one-click installer for Claude Desktop users who prefer it.
