Analysis summary

Verdant Market is an officially published WebMCP tool from OpenAI. Anomity scores its risk at 10 out of 100 (low).

A reference grocery storefront exposing search across roughly 110 products and tools for managing a cart shared between the shopper and the agent. It models the commerce case: the agent does not scrape the catalogue or synthesise clicks, it calls `searchProducts` and `addToCart`.

Commerce is where WebMCP's risk becomes concrete. A cart tool is state-changing and sits inside a session that will eventually reach checkout, so the boundary between "agent helped me shop" and "agent bought something" is a single tool definition. It declares browser control and outbound network access. Real storefronts adopting this pattern should keep irreversible steps — payment, address changes — behind explicit human confirmation rather than behind another tool.

Capabilities

Every capability the entry declares, with the security implication of each.

  • browser:control Browser control
    Drives a browser session. Combined with credential access can impersonate the user on web services.
  • network:outbound Outbound network
    Can make outbound network requests. Required for hosted model providers and remote APIs; also the path for data exfiltration if combined with read access.
