claude's HTTPS_PROXY was catching the supervise MCP URL
(`http://<alias>:<port>/`) because NO_PROXY was hardcoded to
`localhost,127.0.0.1` and didn't include the per-bottle
loopback alias. Claude proxied the MCP POST through egress,
egress had no route for the alias, and the connection failed
— `/mcp` showed "supervise · ✘ failed" inside the bottle.
Append the loopback alias to NO_PROXY in launch.py so direct
MCP calls bypass the proxy. The git-gate URL uses `git://`,
which proxies don't touch, so this only affects MCP / HTTP
paths to the bundle.
