# Perplexity MCP Server for Google Antigravity

> Connect Google Antigravity to Perplexity's hosted MCP server with bearer API-key authentication.

Use Perplexity's hosted [Model Context Protocol (MCP) server](/docs/getting-started/integrations/mcp-server) to give Google Antigravity's agent access to Perplexity search, answers, research, and reasoning. The server runs remotely, so you do not need to install a local package.

## Configure Perplexity MCP in Google Antigravity

<Steps>
  <Step title="Create a Perplexity API key">
    <Card title="Generate API Key" icon="key" arrow="True" horizontal="True" iconType="solid" cta="Get Key" href="https://console.perplexity.ai/project/keys">
      Create an API key in the Perplexity API Portal.
    </Card>
  </Step>

  <Step title="Open the global MCP configuration">
    Open or create `~/.gemini/config/mcp_config.json`. Google Antigravity also supports a workspace-level `.agents/mcp_config.json`, but the global file is the safer place for a configuration containing your API key.

    <Warning>
      Never commit or share API keys. Do not place a literal key in `.agents/mcp_config.json`, because workspace configuration may be committed or shared.
    </Warning>
  </Step>

  <Step title="Add the hosted Perplexity server">
    Add the `perplexity` entry under `mcpServers`. If the file already contains other servers, merge this entry into the existing object.

    ```json theme={null}
    {
      "mcpServers": {
        "perplexity": {
          "serverUrl": "https://api.perplexity.ai/mcp",
          "headers": {
            "Authorization": "Bearer YOUR_PERPLEXITY_API_KEY"
          }
        }
      }
    }
    ```

    Replace `YOUR_PERPLEXITY_API_KEY` with your key. Antigravity requires `serverUrl` for remote Streamable HTTP MCP servers; `url` and `httpUrl` are not supported.
  </Step>

  <Step title="Verify the connection and permissions">
    Save the file and reopen Antigravity if the server does not appear. In MCP management, confirm that the Perplexity server exposes these tools:

    * `perplexity_search`
    * `perplexity_ask`
    * `perplexity_research`
    * `perplexity_reason`

    By default, unconfigured MCP tools run in **Ask** permission mode, so Antigravity requests your approval before running them. You can change tool permissions in Antigravity's policy configuration after confirming the connection works.
  </Step>
</Steps>

<Note>
  Google's public documentation lists `Perplexity Ask` in the [Antigravity MCP Store](https://antigravity.google/docs/mcp#supported-mcp-servers). That Store listing has not been independently verified here. The manual configuration above connects directly to Perplexity's hosted MCP server and does not depend on the Store listing.
</Note>

## MCP tool access vs. Perplexity API calls

This setup lets the **Antigravity agent** call Perplexity through MCP while it works on your project. It does not add Perplexity API calls to the application you are building.

* For more MCP clients, local-server options, billing, and troubleshooting, see the [Perplexity MCP server guide](/docs/getting-started/integrations/mcp-server).
* To call Perplexity from your application code, start with the [Perplexity API quickstart](/docs/getting-started/quickstart).

For other Antigravity MCP settings, see [Google's MCP configuration reference](https://antigravity.google/docs/mcp#mcp-configuration-structure).
