Upgrade Instructions

Docker Compose

cd mcp-gateway-registry
git pull origin main
git checkout 1.32.1

./build_and_run.sh

Kubernetes / Helm (EKS)

The chart values now carry the 1.32.1 image tags, so rebuild chart dependencies before you upgrade. The packaged subcharts under charts/mcp-gateway-registry-stack/charts/ are gitignored and only repackage when you run these commands, so a plain helm upgrade would deploy the previous subcharts.

cd mcp-gateway-registry
git pull origin main
git checkout 1.32.1

cd charts/mcp-gateway-registry-stack
helm dependency build
helm dependency update

helm upgrade mcp-gateway . -f your-values.yaml

Terraform / ECS

cd mcp-gateway-registry
git pull origin main
git checkout 1.32.1

cd terraform/aws-ecs
terraform plan
terraform apply

What's New

Dependency Updates

• Refreshed the weekly lockfiles across the registry and the bundled example servers (#1850)
• Bumped the CI actions group: github/codeql-action/upload-sarif and bridgecrewio/checkov-action (#1848)

Bug Fixes

• Outbound requests through a plain http:// forward proxy failed whenever EGRESS_FORWARD_PROXY_CA_BUNDLE was set. httpcore rejects proxy_ssl_context for the http scheme and raises while it constructs the delegate transport, so the request never left the process. The registry now attaches the context only for an https:// proxy. The upstream leg inside the tunnel still takes the bundle from verify, so nothing is lost for a plain proxy, which has no TLS leg of its own (#1852, closes #1849)

• Capped mcp below 2.0. mcp 2.x renames streamable_http.streamablehttp_client to streamable_http_client with no back-compat alias, which breaks registry/core/mcp_client.py on import. The weekly lockfile refresh in #1850 had pulled in mcp 2.1.1. Moving to 2.x needs the 2.0 changelog reviewed for other behavior changes, so it is tracked separately. The same PR completed the server-repository test mock (#1853)

• The otel-collector container reported a permanent false unhealthy status in docker ps. Its healthcheck shelled out to wget, which the distroless collector image does not ship, so every probe exited -1 while the collector ran normally. The healthcheck is gone, and the comment in docker-compose.yml records why the service has none. Liveness stays visible through the Prometheus scrape of :8889 and the health_check extension on :13133 (#1854)
