+Grok on grok.com, iOS, and Android does not run local `npx` plugins. Add a custom MCP connector at [grok.com/connectors](https://grok.com/connectors) pointing at a public HTTPS Streamable HTTP URL from `@prerenderbuddy/mcp@0.2.1 --http`. See the [MCP README](https://github.com/kopachlager/prerenderbuddy-mcp#streamable-http--grok-bot).

 ## Privacy and safety
 
 Public audit mode has no credentials, hosted API dependency, analytics, or telemetry. Optional workspace mode sends the configured key only to the documented Prerender Buddy Developer API and remains subject to API-side plan, scope, site-limit, and workspace checks. Fetched pages and saved/provider evidence are untrusted input.

 The MCP server runs through `npx --yes @prerenderbuddy/mcp@0.2.0`. It requires Node.js 20 or newer. Its three public audit tools need no account, API key, analytics, or telemetry. When `PRERENDER_BUDDY_API_KEY` is available to the MCP process, it also registers read-only workspace tools backed by the scoped Pro Developer API. Restart the agent host after adding or changing the key.
