# pubchem mcp server

the mcp is used to extract the drug basic chemical infomation from pubchem API.

## Requirements

- Python 3.10
- `python-dotenv`
- `requests`
- `mcp`
- `uvicorn`

## Installation

**Install the dependencies(local):**

- Install directly from the project directory

```bash
git clone [project repository URL]
cd [project directory]
pip install .
```

**Configure servers(pypi):**

The `servers_config.json` follows the same structure as Claude Desktop, allowing for easy integration of multiple servers.
Here's an example:

```json
{
  "mcpServers": {
    "pubchem": {
      "command": "uvx",
      "args": ["pubchem_mcp_server"]
    }
  }
}
```
