Run your coding agent API traffic trough a proxy

docker compose up -d

Look at the container logs and open the link with the auth token.

Then:

cd Projects/project1
export HTTP_PROXY=http://localhost:8080
export HTTPS_PROXY=http://localhost:8080
export NODE_EXTRA_CA_CERTS=/home/martin/Projects/mitmproxy/mitm-data/mitmproxy-ca-cert.pem
claude
# ...
unset HTTP_PROXY
unset HTTPS_PROXY
unset NODE_EXTRA_CA_CERTS
