Module webmcp 

WebMCP tool discovery and execution.

WebMCP is a protocol where websites expose structured tool definitions to AI agents via navigator.modelContext. When a site supports WebMCP, the tools are explicitly defined with typed parameters and return values — the highest-reliability execution path.

WebMCP requires a browser context (the tools live in the page’s JS), but unlike DOM scraping, the tool contract is explicit and machine-readable.

Discovery is opportunistic: Cortex checks for WebMCP only when a browser context is already open (Layer 3 fallback or ACT). It never opens a browser just to check for WebMCP.
