Description

WebMCP is a proposed standard which allows developers to expose their web application functionality as "tools" that agents can then use.
CLARIFICATION: I am not the author, I just thought it needs standards positions.

@jaredcwhite, reactions like this don't give the proposal authors anything to work with. This repo is for substantive technical review. If you think WebMCP is a bad idea, that's a position worth articulating: what are the risks you see? That kind of feedback is what actually helps.

@marcoscaceres The risks are I won't use a browser that includes "agentic" APIs. This is a landgrab to add unethical LLM technology to the one place we have refuge to browse the web as real humans: the traditional web browser. Let other vendors bolt on their own "agentic" tech in their own browser variants (which have yet to prove any real popularity or use cases demanded by the public at large). Allowing Google & Microsoft to shoehorn "agentic" tech into the client-side web API layer is anathema to a broad coalition of the populace which has turned sour on genAI and is fighting back politically, morally, and socially.
