BioClaw brings the power of computational biology directly into WhatsApp group chats. Researchers can run BLAST searches, render protein structures, generate publication-quality plots, perform sequencing QC, and search the literature — all through natural language messages.
Built on the NanoClaw architecture with bioinformatics tools and skills from the STELLA project, powered by the Claude Agent SDK.

The rapid growth of biomedical data, tools, and literature has created a fragmented research landscape that outpaces human expertise. Researchers frequently need to switch between command-line bioinformatics tools, visualization software, databases, and literature search engines — often across different machines and environments.
BioClaw addresses this by providing a conversational interface to a comprehensive bioinformatics toolkit. By messaging @Bioclaw in a WhatsApp group, researchers can:
- Sequence Analysis — Run BLAST searches against NCBI databases, align reads with BWA/minimap2, and call variants
- Quality Control — Generate FastQC reports on sequencing data with automated interpretation
- Structural Biology — Fetch and render 3D protein structures from PDB with PyMOL
- Data Visualization — Create volcano plots, heatmaps, and expression figures from CSV data
- Literature Search — Query PubMed for recent papers with structured summaries
- Workspace Management — Triage files, recommend analysis steps, and manage shared group workspaces
Results — including images, plots, and structured reports — are delivered directly back to the chat.

# Clone the repository
git clone https://github.com/Runchuan-BU/BioClaw.git
cd BioClaw
# Install dependencies
npm install
# Start BioClaw
npm startBioClaw now supports two provider paths:
- Anthropic — default, keeps the original Claude Agent SDK flow
- OpenRouter / OpenAI-compatible — optional path for OpenRouter and similar
/chat/completionsproviders
Create a .env file in the project root and choose one of the following setups.
Option A — Anthropic (default)
ANTHROPIC_API_KEY=your_anthropic_keyOption B — OpenRouter (Gemini, DeepSeek, Claude, GPT, and more)
MODEL_PROVIDER=openrouter
OPENROUTER_API_KEY=sk-or-v1-your-key
OPENROUTER_BASE_URL=https://openrouter.ai/api/v1
OPENROUTER_MODEL=deepseek/deepseek-chat-v3.1Popular model IDs: deepseek/deepseek-chat-v3.1, google/gemini-2.5-flash, anthropic/claude-3.5-sonnet. Full list: openrouter.ai/models
Note: Use models that support tool calling (e.g. DeepSeek, Gemini, Claude). Session history is preserved within a container session; after idle timeout, a new container starts with a fresh context.
Generic OpenAI-compatible setup
MODEL_PROVIDER=openai-compatible
OPENAI_COMPATIBLE_API_KEY=your_api_key
OPENAI_COMPATIBLE_BASE_URL=https://your-provider.example/v1
OPENAI_COMPATIBLE_MODEL=your-model-nameAfter updating .env, restart BioClaw:
npm run devWhen a container starts, docker logs <container-name> will show which provider path is active.
In any connected chat, simply message:
@Bioclaw <your request>
BioClaw supports multiple messaging platforms. Enable one or more by setting the corresponding environment variables in .env.
No credentials needed. On first run, a QR code is printed to the terminal — scan it with your WhatsApp app. Auth state is persisted in store/auth/.
- Log in to the WeCom Admin Console
- Go to Apps & Mini Programs > Smart Robots > Create
- Select API mode with Long Connection (not Callback URL)
- Copy the Bot ID and Secret
- Add to
.env:WECOM_BOT_ID=your-bot-id WECOM_SECRET=your-secret - Add the bot to a group in WeCom, then
@it to start chatting
Image sending (optional): To send images in WeCom, create a self-built app in the admin console and configure:
WECOM_CORP_ID=your-corp-id
WECOM_AGENT_ID=your-agent-id
WECOM_CORP_SECRET=your-corp-secret
The server IP must be added to the app's trusted IP whitelist.
- Go to the Feishu Open Platform and create a self-built app (企业自建应用)
- Enable Bot capability under Add Capabilities
- Under Permissions & Scopes, grant:
im:message— Receive messagesim:message:send_as_bot— Send messages as botim:resource— Download images/files from messagesim:message.group_msg— Receive group messages (if using in groups)
- Under Events & Callbacks, select Long Connection (长连接) mode
- Subscribe to event:
im.message.receive_v1 - Copy the App ID and App Secret, add to
.env:FEISHU_APP_ID=cli_your_app_id FEISHU_APP_SECRET=your_app_secret - Publish the app version and have the admin approve it
- Add the bot to a group or send it a direct message to start chatting
Auto-registration: New chats are automatically registered — no manual setup needed. By default, they use the main group folder. Override with:
FEISHU_DEFAULT_FOLDER=my-folder
Multi-bot support: Up to 3 Feishu bots can run simultaneously (e.g., different agents for different groups):
FEISHU2_APP_ID=cli_second_app_id
FEISHU2_APP_SECRET=second_app_secret
FEISHU2_DEFAULT_FOLDER=literature
FEISHU3_APP_ID=cli_third_app_id
FEISHU3_APP_SECRET=third_app_secret
FEISHU3_DEFAULT_FOLDER=qwen-agent
- Go to the Discord Developer Portal
- Click New Application, then go to Bot > Add Bot
- Enable MESSAGE CONTENT INTENT under Privileged Gateway Intents
- Copy the Bot Token and add to
.env:DISCORD_BOT_TOKEN=your-bot-token - Go to OAuth2 > URL Generator, select scope
bot, grant permissions: Send Messages, Attach Files, Read Message History - Open the generated URL to invite the bot to your Discord server
- Send a message in any channel — the bot auto-registers and responds
To run without WhatsApp (e.g., WeCom/Discord only):
DISABLE_WHATSAPP=1
Just send the message to OpenClaw:
install https://github.com/Runchuan-BU/BioClaw
See the ExampleTask document for 6 ready-to-use demo prompts with expected outputs.
Below are live demonstrations of BioClaw handling real bioinformatics tasks via WhatsApp.
Analyze files in a shared workspace and recommend the best next analysis steps.
Run FastQC on paired-end FASTQ files and deliver the QC report with key findings.
BLAST a protein sequence against the NCBI nr database and return structured top hits.
Create a differential expression volcano plot from a CSV file and interpret the results.
Fetch a PDB structure, render it in rainbow coloring with PyMOL, and send the image.
Search PubMed for recent high-impact papers and provide structured summaries.
Visualize hydrogen bonds between a ligand and protein in PDB 1M17.
Show residues within 5Å of ligand AQ4 in PDB 1M17.
BioClaw is built on the NanoClaw container-based agent architecture, extended with biomedical tools and domain knowledge from the STELLA framework.

Key design principles (inherited from NanoClaw):
| Component | Description |
|---|---|
| Container Isolation | Each conversation group runs in its own Docker container with pre-installed bioinformatics tools |
| Filesystem IPC | Text and image results are communicated between the agent and orchestrator via the filesystem |
| Per-Group State | SQLite database tracks messages, sessions, and group-specific workspaces |
| Channel Agnostic | Channels self-register at startup; the orchestrator connects whichever ones have credentials |
Biomedical capabilities (attributed to STELLA):
The bioinformatics tool suite and domain-specific skills — including sequence analysis, structural biology, literature mining, and data visualization — draw from the tool ecosystem developed in the STELLA project, a self-evolving multi-agent framework for biomedical research.

| BEDTools | Genome arithmetic and interval manipulation |
| BWA | Burrows-Wheeler short read aligner |
| minimap2 | Long read and assembly alignment |
| FastQC | Sequencing quality control reports |
| fastp | FASTQ filtering and trimming (QC/preprocessing) |
| MultiQC | Aggregate QC reports into one summary |
| seqtk | FASTA/FASTQ file manipulation |

| tabix | Index/query compressed VCF/BED (bgzip/tabix) |
| pigz | Parallel gzip compression/decompression |
| SRA Toolkit | Download data from NCBI SRA (prefetch/fasterq-dump) |
| Salmon | RNA-seq transcript quantification |
| kallisto | RNA-seq transcript quantification |
| PyMOL | Molecular visualization and rendering |
| Library | Purpose |
|---|---|
| BioPython | Biological computation (sequences, PDB, BLAST parsing) |
