> Not from this page

Source: https://docs.nocamclub.com/errors/origin_not_allowed

- **Where:** HTTP 403, and nothing started
- **Charged:** No
- **Worth retrying:** Not as it is. The request has to change first.

## What happened

A browser page called the MCP server, and only a few known pages may.

## What to do

Call it from a server, or from a client that sends no `Origin`.

## What it looks like

The real `message` and `hint` name the details of your request, such as the field and the values that work.
