Some environments resolve localhost to ::1 (IPv6) rather than 127.0.0.1, causing connection failures when pyRevit Routes binds only to 127.0.0.1. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

What changed
REVIT_HOSTinmain.pywas changed from"localhost"to"127.0.0.1".Why
On some Windows environments,
localhostresolves to::1(IPv6) rather than127.0.0.1(IPv4). The pyRevit Routes server binds exclusively to127.0.0.1, so an IPv6 resolution causes the MCP server to fail to connect. Using the explicit IPv4 address ensures a reliable connection regardless of the system's hostname resolution behavior.Reviewer notes
No logic changes — purely a hostname string fix. The
BASE_URLalready interpolatesREVIT_HOST, so it now correctly produceshttp://127.0.0.1:48884/revit_mcp.
