Ws MCP

🚀 ws-mcp

Wrap MCP standard input-output servers into WebSocket, suitable for kibitz.

🚀 Quick Start

Prerequisites

Install uv:

curl -LsSf https://astral.sh/uv/install.sh | sh

Configuration

The configuration file specifies which MCP servers to run. If neither the --config nor the --command parameter is provided, the default configuration includes:

• wcgw: For general system operations and file management
• fetch: For making HTTP requests

How to create a configuration file:

1. Copy the example configuration file:

   cp sample.config.json config.json
   

2. Modify config.json to add or remove servers as needed.
3. Run the new configuration file using --config path/to/config.json.

Running ws-mcp

Basic usage with the default configuration file (no --config or --command provided) and port:

uvx --refresh ws-mcp@latest

This will start all configured servers on the default port (10125).

Using a configuration file and port:

uvx --refresh ws-mcp@latest --config path/to/config --port 10125

📚 Documentation

# Example of using fetch
uvx --refresh ws-mcp --command "uvx mcp-server-fetch" --port 3002

# Example of using wcgw
## On macOS
uvx --refresh ws-mcp --command "uvx --from wcgw@latest --python 3.12 wcgw_mcp" --port 3001

## On Linux (or when encountering issues on macOS)
cd /tmp
git clone https://github.com/nick1udwig/wcgw.git
cd wcgw
git submodule update --init --recursive
git checkout hf/fix-wcgw-on-ubuntu
cd ..
uvx --refresh ws-mcp --command "uvx --from /tmp/wcgw --with /tmp/wcgw/src/mcp_wcgw --python 3.12 wcgw_mcp" --port 3001

# Example of using Brave Search
export BRAVE_API_KEY=YOUR_API_KEY_HERE
uvx --refresh ws-mcp --env BRAVE_API_KEY=$BRAVE_API_KEY --command "npx -y @modelcontextprotocol/server-brave-search" --port 3003

# Alternatively, use a .env file:
uvx --refresh ws-mcp --env-file path/to/.env --command "npx -y @modelcontextprotocol/server-brave-search" --port 3003

# The `--command` can be provided multiple times!
# Example of serving multiple servers simultaneously:
uvx --refresh ws-mcp --env-file path/to/.env --command "npx -y @modelcontextprotocol/server-brave-search" --command "uvx mcp-server-fetch" --port 3004

# Servers can also be specified in a `.json` file following the [standard MCP format](https://modelcontextprotocol.io/quickstart/user#2-add-the-filesystem-mcp-server)
uvx --refresh ws-mcp --env-file path/to/.env --config path/to/config.json --port 3005
