## Setup

## Setup

### Installing via Smithery

To install MCP-researcher Server for Claude Desktop automatically via [Smithery](https://smithery.ai/server/@DaInfernalCoder/perplexity-mcp):

```bash
npx -y @smithery/cli install @DaInfernalCoder/perplexity-mcp --client claude
```

### paste this part into claude directly if you want to, the ai can install it for you

1. First install Node.js if not already installed (from nodejs.org)

2. Clone the repo

   - git clone https://github.com/DaInfernalCoder/researcher-mcp perplexity-server
   - cd perplexity-server

3. Install dependencies and build:
   npm install

4. Get a Perplexity API key from [https://www.perplexity.ai/settings/api](https://www.perplexity.ai/settings/api)

5. Create the MCP settings file in the appropriate location for your OS:
   macOS: ~/Library/Application Support/Cursor/User/globalStorage/saoudrizwan.claude-dev/settings/cline_mcp_settings.json
   Windows: %APPDATA%\Cursor\User\globalStorage\saoudrizwan.claude-dev\settings\cline_mcp_settings.json
   Linux: ~/.config/Cursor/User/globalStorage/saoudrizwan.claude-dev/settings/cline_mcp_settings.json

5. To use with Claude Desktop, add the server config:

   On MacOS: `~/Library/Application Support/Claude/claude_desktop_config.json`
   On Windows: `%APPDATA%/Claude/claude_desktop_config.json`

6. To use with Cline, add into mcpServers:

```json
{
  "mcpServers": {
    "perplexity-server": {
      "command": "node",
      "args": [
        "[path/to/researcher-mcp/index.js]"
      ],
      "env": {
        "PERPLEXITY_API_KEY": ""
      },
      "disabled": false,
      "autoApprove": [
        "search",
        "get_documentation",
        "find_apis",
        "check_deprecated_code"
      ]
    }
  }
}
```

7. Build the server:
   npm run build

Make sure to:
- Replace /absolute/path/to with the actual path where you cloned the repository
- Replace your-api-key-here with your Perplexity API key
- Keep the same autoApprove settings for consistent behavior
