# Color Blindness Simulator agent guide

Color Blindness Simulator is a private, browser-based design review tool. It compares an uploaded image with model-based protan, deutan, tritan, and achromatopsia views. Image processing stays in the visitor's browser; the public agent endpoints never accept an image.

## Public tasks

- Search public guidance: `GET /api/agent/search?q=red-green`
- Read one resource: `GET /api/agent/resources/{id}`
- Discover the OpenAPI description: `GET /openapi.json`
- Use the read-only MCP tools: `POST /mcp`
- Read the visitor-facing simulator: <https://colorvisionsimulator.com/>
- Read the five-minute red-green audit: <https://colorvisionsimulator.com/guides/green-red-color-blindness-simulator>

## Supported resource identifiers

- `simulator` — supported views, methods, privacy, and limits.
- `green-red-audit` — practical protan/deutan collision review.
- `method-scope` — method comparison and uncertainty.

## Limitations and provenance

The service exposes only public site guidance. It cannot inspect a visitor's local image, diagnose color vision, or certify accessibility. The resource list is maintained with the site release and points back to canonical pages.
