## Installation

### Installing via Smithery

To install `mcp-sentry-custom` for Claude Desktop automatically via [Smithery](https://smithery.ai/server/@javaDer/mcp-sentry-custom):

```bash
npx -y @smithery/cli install @javaDer/mcp-sentry-custom --client claude
```

### Using `uv` (Recommended)

When using `uv`, no specific installation is required. You can run `mcp-sentry-custom` directly with `uvx`:

```bash
uvx mcp-sentry-custom --auth-token YOUR_SENTRY_TOKEN --project-slug YOUR_PROJECT_SLUG --organization-slug YOUR_ORGANIZATION_SLUG --sentry-url YOUR_SENTRY_URL
```

### Using `pip`

Alternatively, install `mcp-sentry-custom` via `pip`:

```bash
pip install mcp-sentry-custom
```

Or, with `uv`:

```bash
uv pip install -e .
```

After installation, run it as a script:

```bash
python -m mcp_sentry
```

## Debugging

Use the MCP inspector to debug the server.

### For `uvx` Installations
```bash
npx @modelcontextprotocol/inspector uvx mcp-sentry-custom --auth-token YOUR_SENTRY_TOKEN --project-slug YOUR_PROJECT_SLUG --organization-slug YOUR_ORGANIZATION_SLUG --sentry-url YOUR_SENTRY_URL
```

### For Local Development
If you've installed the package in a specific directory or are developing it:

```bash
cd path/to/mcp-sentry-custom/src
npx @modelcontextprotocol/inspector uv run mcp-sentry-custom --auth-token YOUR_SENTRY_TOKEN --project-slug YOUR_PROJECT_SLUG --organization-slug YOUR_ORGANIZATION_SLUG --sentry-url YOUR_SENTRY_URL
```

Or, with a custom directory:

```bash
npx @modelcontextprotocol/inspector uv --directory /path/to/mcp-sentry-custom/src run mcp_sentry --auth-token YOUR_SENTRY_TOKEN --project-slug YOUR_PROJECT_SLUG --organization-slug YOUR_ORGANIZATION_SLUG --sentry-url YOUR_SENTRY_URL
```
