Analysis summary

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

An architecture canvas from Vercel where the diagram itself is agent-callable: tools cover creating nodes, drawing edges, labelling, and running layout, so a model can build and rearrange a diagram from a description rather than emitting an image.

It is a good illustration of the low-risk end of the WebMCP spectrum. The tools mutate a canvas, not a bank account; the declared capability is browser control with outbound network access for the model. Catalogued as a reference point: when reviewing a WebMCP surface, the question is never "does it expose tools" but "what do the tools reach", and a diagram editor and a checkout flow deserve very different answers.
