## 🚀 Getting Started

### Quick Installation

```bash
# 1. Clone the repository
git clone https://github.com/openproblems-bio/SpatialAI_MCP.git
cd SpatialAI_MCP

# 2. Install the package
pip install -e .

# 3. Check installation
openproblems-mcp doctor --check-tools

# 4. Start the server
openproblems-mcp serve
```

### Docker Deployment

```bash
# Build and run with Docker Compose
cd docker
docker-compose up -d
```

### Testing the Installation

```bash
# Run the test suite
openproblems-mcp test

# Try the interactive demo
openproblems-mcp demo

# Get server information
openproblems-mcp info
```

## 🧬 Usage Examples

### For AI Agents

The MCP server enables AI agents to perform complex bioinformatics operations:

```python
# AI agent can execute Nextflow workflows
result = await session.call_tool("run_nextflow_workflow", {
    "workflow_name": "main.nf",
    "github_repo_url": "https://github.com/openproblems-bio/task_ist_preprocessing",
    "profile": "docker",
    "params": {"input": "spatial_data.h5ad", "output": "processed/"}
})

# AI agent can access documentation for context
docs = await session.read_resource("documentation://nextflow")
nextflow_best_practices = json.loads(docs)

# AI agent can analyze failed workflows
analysis = await session.call_tool("analyze_nextflow_log", {
    "log_file_path": "work/.nextflow.log"
})
```

### For Researchers

Direct CLI usage for testing and development:

```bash
# Execute a tool directly
openproblems-mcp tool echo_test message="Hello World"

# Analyze a Nextflow log
openproblems-mcp tool analyze_nextflow_log log_file_path="/path/to/.nextflow.log"

# List all available capabilities
openproblems-mcp info
```
