npm install -g mcpbar
mcpbar install ./manifests/github.json
mcpbar list # show existing mcp servers installed on the device
Install a MCP server from a URL (any protocol supported by fetch), file path, or package alias:
mcpbar install <path-to-manifest.json> # Install from local manifest file
mcpbar i <path-to-manifest.json> # Short alias for install
mcpbar install https://example.com/manifest.json # Install from HTTP URL
mcpbar install file:///path/to/manifest.json # Install using file protocol
mcpbar install vendor/package-name # Install using package alias
Example:
mcpbar install ./manifests/github.json
mcpbar i 21st-dev/magic-mcp
mcpbar install https://esm.sh/gh/in-fun/mcpbar/registry/21st-dev/magic-mcp.json
mcpbar install file:///Users/username/projects/manifests/custom.json
Open the configuration file for an MCP client directly in your default editor:
mcpbar edit # Edit configuration for the default client (claude)
mcpbar edit --client cursor # Edit configuration for a specific client
mcpbar e --client witsy # Short alias for edit
If the configuration file doesn't exist, the command will offer to create an empty file for you.

🧩 MCP Manifest Concept
MCPBar implements a standardized approach for MCP servers using mcp.json manifest files. This solution:
- 📄 Uses a standardized manifest format (mcp.json) similar to package.json in npm
- 🌐 Supports a decentralized distribution model where developers can host manifests anywhere
- 🔄 Allows installation directly from URLs, local files, or package aliases
- 🔍 Features an optional registry for enhanced discoverability
- 🔐 Securely handles server configuration with explicit handling of sensitive inputs
- 📚 Includes an open registry with 1500+ MCP servers in the registry directory
- 🐳 Supports multiple runtime options including npx, uvx and docker
This approach simplifies discovery, installation, and configuration of MCP servers across different clients, making the MCP ecosystem more accessible and organized.
The extensive registry is the foundation of an open and standardized MCP ecosystem, enabling developers to easily discover, share, and contribute to the growing collection of MCP servers.
