## Local Development without North

This guide describes how to test your MCP server locally without connecting it to North. For this, we will use the MCP Inspector. You can run it with:
```


```sh
npx @modelcontextprotocol/inspector

### Adding authentication

If you want to test the authentication mechanism locally you can do the following. First start the server with the streamable http transport:

```
uv run examples/server_with_auth.py --transport streamable-http
```

Next, create a bearer token. You can generate one using `examples/create_bearer_token.py` or use a pre-made one.
Next, start MCP inspector in your terminal, and copy the Session Token it outputs to your clipboard.

It will then automatically open the browser - paste the session token into `Configuration > Proxy Session Token` field.

```sh
npx @modelcontextprotocol/inspector
```

Configure the rest of your MCP inspector with the following settings:

| Field | Value |
|---|---|
|Transport Type|Streamable HTTP|
|URL|http://localhost:5222/mcp (or wherever your local MCP server is running)|
|Connection Type|Via Proxy (very important)|
|Authentication > Custom Headers|See Below|
|Proxy Session Token|The token you copied from the previous step|

For Custom Headers, include the following:

Navigate to the MCP Inspector and configure it like this:
* Transport Type: Streamable HTTP
* URL: http://localhost:5222/mcp
* Authentication -> Bearer token: eyJzZXJ2ZXJfc2VjcmV0IjogInNlcnZlcl9zZWNyZXQiLCAidXNlcl9pZF90b2tlbiI6ICJleUpoYkdjaU9pSklVekkxTmlJc0luUjVjQ0k2SWtwWFZDSjkuZXlKbGJXRnBiQ0k2SW5SbGMzUkFZMjl0Y0dGdWVTNWpiMjBpZlEuV0pjckVUUi1MZnFtX2xrdE9vdjd0Q1ktTmZYR2JuYTVUMjhaeFhTaEZ4SSIsICJjb25uZWN0b3JfYWNjZXNzX3Rva2VucyI6IHsiZ29vZ2xlIjogImFiYyJ9fQ==

You can use this token, or generate your own using [examples/create_bearer_token.py](examples/create_bearer_token.py).


Next, create a bearer token. You can generate one using `examples/create_bearer_token.py` or use a pre-made one.

Follow the same process as before. When you call the tool, you should see the following log in the terminal where you started the server:
