## Prerequisites

- Python 3.12 or later
- [uv](https://docs.astral.sh/uv/) package manager
- A LinkedIn account for authentication

---

## Quick Start

### 1. Clone and install

```bash
git clone https://github.com/eliasbiondo/linkedin-mcp-server.git
cd linkedin-mcp-server
uv sync
```

### 2. Install browser

This project uses [Patchright](https://github.com/Kaliiiiiiiiii-Vinyzu/patchright) (a patched fork of Playwright) for browser automation. You need to install the browser binaries before first use:

```bash
uv run patchright install
```

> **Windows users:** If the command above fails with `program not found`, run instead:
>
> ```powershell
> uv run python -m patchright install
> ```

### 3. Authenticate with LinkedIn

```bash
uv run linkedin-mcp-server --login
```

A browser window will open. Log in to LinkedIn and the session will be persisted locally at `~/.linkedin-mcp-server/browser-data`.

### 4. Run the server

**stdio transport** (default — for Claude Desktop, Cursor, and similar clients):

```bash
uv run linkedin-mcp-server
```

**HTTP transport** (for remote clients, the MCP Inspector, etc.):

```bash
uv run linkedin-mcp-server --transport streamable-http --host 0.0.0.0 --port 8000
```

---

## Client Integration

### Claude Desktop / Cursor

Add to your MCP configuration file:

```json
{
  "mcpServers": {
    "linkedin": {
      "command": "uv",
      "args": [
        "--directory", "/path/to/linkedin-mcp-server",
        "run", "linkedin-mcp-server"
      ]
    }
  }
}
```

### MCP Inspector

```bash
npx @modelcontextprotocol/inspector
```

Then connect to `http://localhost:8000/mcp` if using HTTP transport.

---

## Configuration

Configuration follows a strict precedence chain: **CLI args > environment variables > `.env` file > defaults**.

### CLI Arguments

| Argument        | Description                         | Default     |
| --------------- | ----------------------------------- | ----------- |
| `--transport`   | `stdio` or `streamable-http`        | `stdio`     |
| `--host`        | Host for HTTP transport             | `127.0.0.1` |
| `--port`        | Port for HTTP transport             | `8000`      |
| `--log-level`   | `DEBUG`, `INFO`, `WARNING`, `ERROR` | `WARNING`   |
| `--headless`    | Run browser in headless mode        | `true`      |
| `--no-headless` | Show browser window (visible mode)  | —           |
| `--login`       | Open browser for LinkedIn login     | —           |
| `--logout`      | Clear stored credentials            | —           |
| `--status`      | Check session status                | —           |

### Environment Variables

Create a `.env` file in the project root:

```env
# Server
LINKEDIN_TRANSPORT=stdio
LINKEDIN_HOST=127.0.0.1
LINKEDIN_PORT=8000
LINKEDIN_LOG_LEVEL=WARNING

# Browser
LINKEDIN_HEADLESS=true
LINKEDIN_SLOW_MO=0
LINKEDIN_TIMEOUT=10000
LINKEDIN_VIEWPORT_WIDTH=1280
LINKEDIN_VIEWPORT_HEIGHT=720
LINKEDIN_CHROME_PATH=
LINKEDIN_USER_AGENT=
LINKEDIN_USER_DATA_DIR=~/.linkedin-mcp-server/browser-data
```

## Architecture

The project follows a hexagonal (ports and adapters) architecture with strict layer separation:

```
src/linkedin_mcp_server/
├── domain/              # Core business logic — zero external dependencies
│   ├── models/          # Data models (Person, Company, Job, Search)
│   ├── parsers/         # HTML to structured data parsers
│   ├── exceptions.py    # Domain exceptions
│   └── value_objects.py # Immutable configuration and content objects
├── ports/               # Abstract interfaces
│   ├── auth.py          # Authentication port
│   ├── browser.py       # Browser automation port
│   └── config.py        # Configuration port
├── application/         # Use cases — orchestration layer
│   ├── scrape_person.py
│   ├── scrape_company.py
│   ├── scrape_job.py
│   ├── search_people.py
│   ├── search_jobs.py
│   └── manage_session.py
├── adapters/            # Concrete implementations
│   ├── driven/          # Infrastructure adapters (browser, auth, config)
│   └── driving/         # Interface adapters (CLI, MCP tools, serialization)
└── container.py         # Dependency injection composition root
```

### Design Decisions

- **Ports and adapters** — Domain logic is fully decoupled from infrastructure. The browser engine, MCP framework, and configuration source can all be swapped independently.
- **Dependency injection** — A single `Container` class acts as the composition root and is the only place that imports concrete adapter classes.
- **Structured JSON output** — LinkedIn HTML is parsed into typed Python dataclasses, then serialized to JSON for reliable LLM consumption.
- **Session persistence** — Browser state is saved to disk, so authentication is required only once.

## Development

### Setup

```bash
uv sync --group dev
uv run pre-commit install
```

### Running tests

```bash
uv run pytest
```

With coverage:

```bash
uv run pytest --cov=linkedin_mcp_server
```

### Linting and formatting

This project uses [Ruff](https://docs.astral.sh/ruff/) for both linting and formatting. Pre-commit hooks will run these automatically on each commit.

```bash
# Lint
uv run ruff check .

# Lint and auto-fix
uv run ruff check . --fix

# Format
uv run ruff format .
```
