# Development
## Watching changes
The following command watches for changes.
```sh
pnpm run dev
```
It builds JavaScript output that can be then in turn ran by MCP client.
If you want to continuously run the tests, then execute as well:
```sh
pnpm run test:watch
```
## MCP Inspector client
You can use [MCP Inspector](https://modelcontextprotocol.io/docs/tools/inspector) as MCP client to debug your MCP server.
Start:
```sh
pnpm run inspect
```
Every time you rebuild the MCP server script, you need to **Restart** the Inspector tool.
Every time you change the tool definition, you should **Clear** and then **List** the tool again.
If you want to debug the MCP server code, you need to configure the MCP server with **debugging** enabled:
| key | value |
| --- | --- |
| Command | node |
| Arguments | --inspect build/index.js |
Connect Chrome Debugger by opening `chrome://inspect`.
## Building
The build process is triggered by running:
```sh
pnpm run build
```
Verify the code quality with:
```sh
pnpm run test
```
Check also the code coverage with:
```sh
pnpm run test:coverage
```
