# LabClaw

**Cloud Brain — unified gateway to 2400+ scientific tools.**

LabClaw gives scientists and developers a single interface to access scientific databases and AI tools: PubMed, UniProt, ChEMBL, PubChem, OpenTargets, and 2000+ more via [ToolUniverse](https://github.com/mims-harvard/ToolUniverse).

## Install

```bash
pip install labclaw
# For ToolUniverse tools:
pip install labclaw[tooluniverse]
# For LLM-powered features (reasoning, writing):
pip install labclaw[llm]
# Everything:
pip install labclaw[all]
```

## Quick Start

```bash
# Try it
labclaw demo

# Start Cloud Brain REST API
labclaw brain

# Start MCP server (for Claude Desktop)
labclaw mcp

# List available tools
labclaw tools
```

## Python SDK

```python
from labclaw.brain import execute, list_tools, reason, write

# Search PubMed
result = await execute("search_pubmed", query="CRISPR delivery")

# Life science reasoning
answer = await reason("What controls circadian rhythm in Drosophila?")

# Scientific writing
section = await write(section="methods", context="We performed RNA-seq on 3 replicates...")

# List tools
tools = await list_tools(category="genomics")
```

## REST API

```bash
curl http://localhost:18802/brain/health
curl http://localhost:18802/brain/tools
curl -X POST http://localhost:18802/brain/execute \
  -H "Content-Type: application/json" \
  -d '{"tool_name": "search_pubmed", "arguments": {"query": "CRISPR"}}'
```
