# Guardian Browser

> Guardian is a privacy-focused browser and multi-engine search service for people and software agents, with deterministic Agent Mode search and machine-readable discovery endpoints.

Use the public website for human-facing pages and the API host for JSON search. Agent search is available at `https://api.guardianbrowser.sh/v1/agent/search` and accepts the same query controls as Guardian Search, including engine selection and Safe Search. Signed-in Guardian clients can use `https://api.guardianbrowser.sh/v1/agent/plan` with sanitized page context for guided scenarios. Website credentials remain local to Apple Password AutoFill or the user-selected credential provider and are not part of the agent payload. The Guardian app also supports `guardian://` deep links for agent-friendly search, Agent Assist, and direct URL opening.

## Search and agent interfaces

- [Guardian Search](https://guardianbrowser.sh/search?mode=agent): Browser-based search with Agent Mode available through the search settings control or the `mode=agent` query parameter.
- [Guardian Agent Bridge](https://guardianbrowser.sh/agent): Human- and agent-readable entry point for launching a goal into Guardian Agent Assist or Agent Search.
- [Guardian Search MCP](https://mcp.guardianbrowser.sh/v1): Streamable HTTP MCP endpoint with `search_web`, `search_shopping`, `discover_sites`, and `finance_quote`.
- [Guardian Search for Business](https://guardianbrowser.sh/business): MCP connection examples, result schema, and production agent-search overview.
- [Guardian OpenAPI](https://api.guardianbrowser.sh/v1/openapi.json): Machine-readable API schema, including `/v1/agent/search` and the authenticated `/v1/agent/plan` scenario-planning endpoint.
- [Guardian agent manifest](https://guardianbrowser.sh/.well-known/guardian-agent.json): Agent discovery metadata, search templates, deep-link templates, and stable accessibility identifiers.
- [OpenSearch description](https://guardianbrowser.sh/opensearch.xml): Search-engine discovery for Guardian's HTML and JSON search interfaces.

## Hermes Agent

For Hermes Agent on macOS, use Browser Automation for the public Guardian website and Computer Use for the native Guardian application. Run `hermes tools` to enable the relevant toolsets. For native app control, run `hermes computer-use doctor`, grant the reported identity Accessibility and Screen Recording access, then start `hermes -t computer_use chat`. In the terminal CLI, `/browser connect` and `/browser status` can attach Hermes to a signed-in Chromium-family browser. Guardian's search settings include a modal Hermes guide with the same human-readable setup information.

## Guardian Pro

Guardian Pro uses the App Store product `guardianbrowserpro399` and is intended to be priced at USD $3.99 per month in the United States storefront. Pro unlocks mobile Agent Assist and AI Text Signals. AI-text classification is probabilistic and must not be treated as proof of authorship. On-device scanning is preferred; signed-in users can explicitly request a deeper scan at `https://api.guardianbrowser.sh/v1/pro/ai-text/analyze`. The backend can optionally enforce Pro with an Apple-signed StoreKit transaction JWS.
