VSCode Extension

The Extension is open-source and at https://github.com/jasonkneen/mcpz-vscode and in the mcspx-tweaks branch

https://github.com/jasonkneen/mcpz-vscode

mcpz cli

Command line interface for mcpsx (Model Context Protocol Server eXecutable), allowing you to manage, query, and interact with Model Context Protocol (MCP) servers and tools.

Installation

# Install globally
npm install -g @mcpz/cli

# Or use with npx
npx @mcpz/cli

Usage

The CLI can be accessed using any of these commands:

mcps (primary command)
mcpz (extended alias)

# Show help
mcpz help

# Start MCPS as a stdio server
mcpz run

# Start with specific servers and tools
mcpz run --server="sleep"
mcpz run --servers="python,pytorch" --tool="predict"

# Server group management
mcpz groups add "python-stack" --servers="python,pytorch,huggingface"
mmcpzcpsx run --servers="python-stack"

# Add a new MCP configuration
mcpz add "My Server" --command "node" --args "server.js"

# List MCP configurations
mcpz list

# Remove an MCP configuration
mcpz remove "My Server"

# Use a specific MCP configuration
mcpz use "My Server"

Key Features

mcpz CLI provides powerful capabilities for working with Model Context Protocol servers:

Run Servers & Tools: Start MCP servers and tools individually or in combination
Add & Remove: Easily manage your MCP configurations
Query & List: View available servers and tools at any time
Grouping: Create and manage groups of servers and tools for simplified workflows
Flexible Filtering: Run specific servers, tools, or combinations

Commands

`run`

Start mcpz as a stdio server. This is the main command used by the VSCode extension to communicate with MCP servers.

mcpz run [options]

Options:

-s, --server <n> - Load only a specific server
-S, --servers <names> - Load only specific servers (comma-separated)
-t, --tool <n> - Load only a specific tool
-T, --tools <names> - Load only specific tools (comma-separated)

Examples:

# Load all servers and tools
mcpz run

# Load only the 'sleep' server
mcpz run --server="sleep"

# Load multiple servers
mcpz run --servers="python,pytorch"

# Load specific tools from specific servers
mcpz run --servers="python" --tools="predict,generate"

# Use a server group
mcpz run --servers="python-stack"

`groups`

Manage server and tool groups. Groups allow you to create collections of MCP servers and tools that can be used together.

mcpz groups <command>

Subcommands:

`groups add`

Create a new server group.

mcpz groups add <n> --servers="server1,server2,..."

Example:

# Create a 'python-stack' group containing multiple servers
mcpz groups add "python-stack" --servers="python,pytorch,huggingface"

# Create a 'favorites' group
mcpz groups add "favorites" --servers="openai,anthropic"

`groups remove`

Remove a server group.

mcpz groups remove <n>

`groups list`

List all server groups.

mcpz groups list

Server & Tool Groups

Groups allow you to create collections of MCP servers and tools that can be used together. This is useful for organizing related components and simplifying command-line usage.

Groups act as "virtual MCPs" - when you reference a group name with --servers or --tools, it expands to include all servers or tools in that group.

Example workflow:

# Create groups for different use cases
mcpz groups add "ai-models" --servers="openai,anthropic,llama"
mcpz groups add "data-tools" --servers="pandas,numpy,sklearn"

# Use a specific group
mcpz run --servers="ai-models"

# Combine groups with individual servers/tools
mcpz run --servers="ai-models,custom-server" --tools="predict"

`add`

Add a new MCP configuration.

mcpz add <n> [options]

Options:

-c, --command <command> - Command to run the MCP server
-a, --args <args> - Arguments for the command (comma-separated)
-e, --env <env> - Environment variables (key=value,key2=value2)

Example:

mcpz add "GPT Server" --command "node" --args "server.js,--port=3000" --env "API_KEY=abc123,DEBUG=true"

`remove`

Remove an MCP configuration.

mcpz remove <n>

`list`

List all MCP configurations.

mcpz list

`use`

Use a specific MCP configuration.

mcpz use <n>

`help`

Display help information.

mcpz help

Configuration

MCPSX CLI uses the configuration file located at ~/.mcpsx/config.json. This file is shared with the MCPS VSCode extension.
