# MCP-servers

This is "a" version focued on enabling to web browsing from Claude app of model context procol projects.
It's derived from [Model Context Protocol](https://github.com/ppl-ai/modelcontextprotocol) and Anthropic's original MCP project.
You can see the instructions and their LICENSEs on those READMEs to use this app.

## Tools

- **perplexity_ask**
  - Engage in a conversation with the Sonar API for live web searches.
  - **Inputs:**
    - `messages` (array): An array of conversation messages.
      - Each message must include:
        - `role` (string): The role of the message (e.g., `system`, `user`, `assistant`).
        - `content` (string): The content of the message.

## Configuration

### Step 1:

Clone this repository:

```bash
git clone git@github.com:rascal-3/MCP-servers.git
```

Navigate to the `perplexity-ask` directory and install the necessary dependencies:

```bash
cd servers/src/perplexity-ask && npm install
```

### Step 2: Get a Sonar API Key

1. Sign up for a [Sonar API account](https://docs.perplexity.ai/guides/getting-started).
2. Follow the account setup instructions and generate your API key from the developer dashboard.
3. Set the API key in your environment as `PERPLEXITY_API_KEY`.

### Step 3: Configure Claude Desktop

1. Download Claude desktop [here](https://claude.ai/download).

2. Add this to your `claude_desktop_config.json`:

```json
{
  "mcpServers": {
    "perplexity-ask": {
      "command": "docker",
      "args": [
        "run",
        "-i",
        "--rm",
        "-e",
        "PERPLEXITY_API_KEY",
        "mcp/perplexity-ask"
      ],
      "env": {
        "PERPLEXITY_API_KEY": "YOUR_API_KEY_HERE"
      }
    }
  }
}
```

### NPX

```json
{
  "mcpServers": {
    "perplexity-ask": {
      "command": "npx",
      "args": ["-y", "server-perplexity-ask"],
      "env": {
        "PERPLEXITY_API_KEY": "YOUR_API_KEY_HERE"
      }
    }
  }
}
```

You can access the file using:

```bash
vim ~/Library/Application\ Support/Claude/claude_desktop_config.json
```

### Step 4: Build the Docker Image

Docker build:

```bash
docker build -t [your-docker-hub-account]/perplexity-ask:latest -f Dockerfile .
```

### Step 5: Testing

Docker run:

```bash
docker image ls
docker run -it [your-container-image-id]
```

Let's make sure Claude for Desktop is picking up the two tools we've exposed in our `perplexity-ask` server. You can do this by looking for the hammer icon:

![Claude Visual Tools](src/perplexity-ask/assets/visual-indicator-mcp-tools.png)

After clicking on the hammer icon, you should see the tools that come with the Filesystem MCP Server:

![Available Integration](src/perplexity-ask/assets/available_tools.png)

If you see both of these this means that the integration is active. Congratulations! This means Claude can now ask Perplexity. You can then simply use it as you would use the Perplexity web app.

### Step 6: Advanced parameters

Currently, the search parameters used are the default ones. You can modify any search parameter in the API call directly in the `index.ts` script. For this, please refer to the official [API documentation](https://docs.perplexity.ai/api-reference/chat-completions).

### Troubleshooting

The Claude documentation provides an excellent [troubleshooting guide](https://modelcontextprotocol.io/docs/tools/debugging) you can refer to. However, you can still reach out to us at api@perplexity.ai for any additional support or [file a bug](https://github.com/ppl-ai/api-discussion/issues).
