+# MCP Gateway
+
+A flexible gateway server that bridges Model Context Protocol (MCP) STDIO servers to HTTP+SSE, enabling multi-instance MCP servers to be exposed over HTTP.
+
+## Features
+
+- Run multiple instances of the same MCP server type
+- Configure multiple different MCP server types
+- Flexible network binding configuration
+- Clean separation between server instances using session IDs
+- Automatic cleanup of server resources on connection close
+- YAML-based configuration
+
+## Installation
+
+```bash
+npm install
+```
+
+## Configuration
+
+The gateway is configured using a YAML file. By default, it looks for `config.yaml` in the current directory, but you can specify a different path using the `CONFIG_PATH` environment variable.
+
+### Basic Configuration Example
+
+```yaml
+hostname: "0.0.0.0"  # Listen on all interfaces
+port: 3000
+
+servers:
+  filesystem:
+    command: npx
+    args:
+      - -y
+      - "@modelcontextprotocol/server-filesystem"
+      - "/path/to/root"
+    
+  git:
+    command: npx
+    args:
+      - -y
+      - "@modelcontextprotocol/server-git"
+```
+
+### Network Configuration Examples
+
+#### Listen on localhost only (development)
+```yaml
+hostname: "127.0.0.1"
+port: 3000
+```
+
+#### Listen on a specific interface
+```yaml
+hostname: "192.168.1.100"
+port: 3000
+```
+
+#### Listen on all interfaces (default)
+```yaml
+hostname: "0.0.0.0"
+port: 3000
+```
+
+### Server Configuration
+
+Each server in the `servers` section needs:
+
+- `command`: The command to run the server
+- `args`: List of arguments for the command
+- `path` (optional): Working directory for the server
+
+Example with all options:
+```yaml
+servers:
+  myserver:
+    command: npx
+    args:
+      - -y
+      - "@modelcontextprotocol/server-mytype"
+      - "--some-option"
+```
+
+## Running the Gateway
+
+Standard start:
+```bash
+npm start
+```
+
+With custom config:
+```bash
+CONFIG_PATH=/path/to/my/config.yaml npm start
+```
+
+## Adding New Server Types
+
+1. Install the MCP server package you want to use
+2. Add a new entry to the `servers` section in your config:
+```yaml
+servers:
+  mynewserver:
+    command: npx
+    args:
+      - -y
+      - "@modelcontextprotocol/server-newtype"
+      # Add any server-specific arguments here
+```
+
+## Architecture
+
+The gateway creates a unique session for each server instance, allowing multiple clients to use the same server type independently. Each session maintains its own:
+
+- STDIO connection to the actual MCP server
+- SSE connection to the client
+- Message bridging between the transports
+
+When a client disconnects, all associated resources are automatically cleaned up.
+
+## Environment Variables
+
+- `CONFIG_PATH`: Path to the YAML configuration file (default: `./config.yaml`)
+
+## Contributing
+
+Feel free to submit issues and pull requests!
