What
When an HTTP MCP server returns 404 on connect, the error message quotes just the URL origin instead of the full path.
Details
- previously interpolated the sanitized URL, with query, credentials and hash stripped and the trailing slash removed
- now interpolates only the origin, so the request path is no longer echoed back in the error
Evidence
Check the URL in your MCP config.
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
