### Installation
```bash
git clone https://github.com/wso2/open-mcp-auth-proxy
cd open-mcp-auth-proxy
go get github.com/golang-jwt/jwt/v4 gopkg.in/yaml.v2
go build -o openmcpauthproxy ./cmd/proxy
```
### Basic Usage
1. Download the latest release from [Github releases](https://github.com/wso2/open-mcp-auth-proxy/releases/latest).
1. The repository comes with a default `config.yaml` file that contains the basic configuration:
```yaml
listen_port: 8080
base_url: "http://localhost:8000" # Your MCP server URL
paths:
sse: "/sse"
messages: "/messages/"
```
2. Start the proxy in demo mode (uses pre-configured authentication with Asgardeo sandbox):

3. Connect using an MCP client like [MCP Inspector](https://github.com/shashimalcse/inspector)(This is a temporary fork with fixes for authentication [issues](https://github.com/modelcontextprotocol/typescript-sdk/issues/257) in the original implementation)
## Connect an Identity Provider
## Identity Provider Integration
### Asgardeo
### Demo Mode
To enable authorization through your Asgardeo organization:
For quick testing, use the `--demo` flag which includes pre-configured authentication and authorization with an Asgardeo sandbox.
```bash
./openmcpauthproxy --demo
```
### Asgardeo Integration
To enable authorization through your own Asgardeo organization:
1. [Register](https://asgardeo.io/signup) and create an organization in Asgardeo
2. Create an [M2M application](https://wso2.com/asgardeo/docs/guides/applications/register-machine-to-machine-app/)
1. [Authorize this application](https://wso2.com/asgardeo/docs/guides/applications/register-machine-to-machine-app/#authorize-the-api-resources-for-the-app) to invoke "Application Management API" with the `internal_application_mgt_create` scope
![image](https://github.com/user-attachments/assets/0bd57cac-1904-48cc-b7aa-0530224bc41a)
2. Update the existing `config.yaml` with your Asgardeo details:
3. Update `config.yaml` with the following parameters.
#### Configure the Auth Proxy
Create a configuration file config.yaml with the following parameters:
```yaml

## Testing with an Example MCP Server
If you don't have an MCP server, you can use the included example:
1. Navigate to the `resources` directory
2. Set up a Python environment:
```bash
python3 -m venv .venv
source .venv/bin/activate
pip3 install -r requirements.txt
```
3. Start the example server:
