## In-browser agents (WebMCP)

On any CacheBy page, read-only tools are registered on `document.modelContext`:
`search_products`, `search_by_cas`, `compare_reagent_prices`, `get_substitutes`,
`get_similar_products`.

## Scope

Read-only by design. Cart, ordering, quoting and payment are not exposed programmatically.
