ws-mcp

Wrap MCP stdio servers with a WebSocket. For use with kibitz.

Quickstart

Prerequisites

Install uv:

hljs language-bash

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

Configuration

The config file specifies which MCP servers to run. The default config (no --config or --command args provided) includes:

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

To make a configuration file:

Create your configuration file:
hljs language-bash
```
cp sample.config.json config.json
```
Modify config.json to add or remove servers based on your needs.
Run with --config path/to/config.json to use the new config file.

Running ws-mcp

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

hljs language-bash

uvx --refresh ws-mcp@latest

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

To use a config file and port:

hljs language-bash

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

Detailed Usage

hljs language-bash

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

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

# Example 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

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

# `--command` can be supplied multiple times!
#  Example serving multiple servers at once:
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
