Setup

1. Get an API key (optional but recommended)

Get a free key at semanticscholar.org/product/api. Without a key, requests are heavily rate-limited.

2. Install and build

cd semanticscholar-mcp-server
npm install
npm run build

3. Add to Claude Desktop

Add this to your claude_desktop_config.json:

{
  "mcpServers": {
    "semantic-scholar": {
      "command": "node",
      "args": ["/path/to/semanticscholar-mcp-server/dist/index.js"],
      "env": {
        "SEMANTICSCHOLAR_API_KEY": "your-api-key"
      }
    }
  }
}

Or if using Claude Code CLI:

claude mcp add semantic-scholar \
  node \
  /path/to/semanticscholar-mcp-server/dist/index.js \
  -e SEMANTICSCHOLAR_API_KEY=your-api-key
