# PubTator MCP Server
[](https://smithery.ai/server/@JackKuo666/pubtator-mcp-server)
🔍 A biomedical literature annotation and relationship mining server based on PubTator3, providing convenient access through the MCP interface.
PubTator MCP Server provides AI assistants with access to the PubTator3 biomedical literature annotation system through the Model Context Protocol (MCP). It allows AI models to programmatically search scientific literature, obtain annotation information, and analyze entity relationships.

##### Claude
```sh
npx -y @smithery/cli@latest install @JackKuo666/pubtator-mcp-server --client claude --config "{}"
```
##### Cursor
Paste in Settings → Cursor Settings → MCP → Add new server:
- Mac/Linux

```
##### Windsurf
```sh
npx -y @smithery/cli@latest install @JackKuo666/pubtator-mcp-server --client windsurf --config "{}"
```
##### CLine
```sh
npx -y @smithery/cli@latest install @JackKuo666/pubtator-mcp-server --client cline --config "{}"
```
#### Manual Installation
1. Clone the repository:
```
git clone https://github.com/JackKuo666/PubTator-MCP-Server.git
cd PubTator-MCP-Server
```
2. Install dependencies:
```
pip install -r requirements.txt
```
## 📊 Usage
### Running the Server Directly
Start the MCP server:
```bash
python pubtator_server.py
```
The server now supports both stdio and TCP transports. By default, it uses TCP transport. You can configure the following environment variables:
- `MCP_TRANSPORT`: Set to "tcp" for TCP transport or "stdio" for stdio transport (default is "tcp")
- `MCP_HOST`: The host to bind to (default is "0.0.0.0")
- `MCP_PORT`: The port to listen on (default is 8080)
Example of starting the server with custom settings:
```bash
MCP_TRANSPORT=tcp MCP_HOST=127.0.0.1 MCP_PORT=8888 python pubtator_server.py
```
The server implements lazy initialization and proper error handling. It will gracefully handle shutdown signals (SIGINT and SIGTERM) and log any errors that occur during startup or operation.
### Using Docker
We provide a Dockerfile for easy deployment. To use the Docker container:
1. Build the Docker image:
```bash
docker build -t pubtator-mcp-server .
```
2. Run the Docker container:
```bash
docker run -p 8080:8080 pubtator-mcp-server
```
This will start the PubTator MCP server inside a Docker container, exposing it on port 8080.
### Troubleshooting
If you encounter any issues starting the server:
1. Check the console output for error messages.
2. Ensure all required dependencies are installed (see Requirements section).
3. Verify that the environment variables are set correctly.
4. If the server fails to start, try running it with increased verbosity:
```bash
python -v pubtator_server.py
```
This will provide more detailed logging information to help identify the source of any issues.
When using Docker, you can check the logs with:
```bash
docker logs <container_id>
```
### Configuration
#### Claude Desktop Configuration
Add to `claude_desktop_config.json`:
(Mac OS)
```json
{
"mcpServers": {
"pubtator": {
"command": "python",
"args": ["-m", "pubtator-mcp-server"]
}
}
}
```
(Windows)
```json
{
"mcpServers": {
"pubtator": {
"command": "C:\\Users\\YOUR\\PATH\\miniconda3\\envs\\mcp_server\\python.exe",
"args": [
"D:\\code\\YOUR\\PATH\\PubTator-MCP-Server\\pubtator_server.py"
],
"env": {},
"disabled": false,
"autoApprove": []
}
}
}
```
#### CLine Configuration
```json
{
"mcpServers": {
"pubtator": {
"command": "bash",
"args": [
"-c",
"source /home/YOUR/PATH/mcp-server-pubtator/.venv/bin/activate && python /home/YOUR/PATH/pubtator_server.py"
],
"env": {
"MCP_TRANSPORT": "stdio"
},
"disabled": false,
"autoApprove": []
}
}
}
```
To use TCP transport, modify the configuration as follows:
```json
{
"mcpServers": {
"pubtator": {
"command": "bash",
"args": [
"-c",
"source /home/YOUR/PATH/mcp-server-pubtator/.venv/bin/activate && python /home/YOUR/PATH/pubtator_server.py"
],
"env": {
"MCP_TRANSPORT": "tcp",
"MCP_HOST": "127.0.0.1",
"MCP_PORT": "8888"
},
"disabled": false,
"autoApprove": []
}
}
}
```
## 🛠 API Features
PubTator MCP Server provides the following core features:
### 1. Export Publications (export_publications)
Export PubTator annotation results for specified PMID literature:
```python
result = await export_publications(
ids=["32133824", "34170578"],
id_type="pmid",
format="biocjson", # Supported: pubtator, biocxml, biocjson
full_text=False # Whether to include full text
)
```
### 2. Entity ID Lookup (find_entity_id)
Query standard identifiers for biological concepts through free text:
```python
result = await find_entity_id(
query="COVID-19",
concept="disease", # Optional: gene, disease, chemical, species, mutation
limit=5 # Optional: limit number of results
)
```
### 3. Relationship Query (find_related_entities)
Find other entities related to a specified entity:
```python
result = await find_related_entities(
entity_id="@DISEASE_COVID_19",
relation_type="treat", # Optional: treat, cause, interact, etc.
target_entity_type="chemical", # Optional: gene, disease, chemical
max_results=5 # Optional: limit number of results
)
```
### 4. Literature Search (search_pubtator)
Search the PubTator database:
```python
results = await search_pubtator(
query="COVID-19",
max_pages=1 # Optional: maximum number of pages to retrieve
)
```
### 5. Batch Export (batch_export_from_search)
Search and batch export literature annotations:
```python
results = await batch_export_from_search(
query="COVID-19",
format="biocjson",
max_pages=1,
full_text=False,
batch_size=5
)
```
Note: The actual function calls may vary depending on your implementation. These examples are based on our recent tests and may need to be adjusted to match your exact API.
## ⚠️ Usage Limitations
- API request rate limit: maximum 3 requests per second
- When batch exporting, use a reasonable batch_size to avoid request timeout
- For relationship queries, entity IDs must start with "@", e.g., "@DISEASE_COVID-19"
