Release v1.6.0 · agentgateway/agentgateway
🎉 Welcome to the 1.6.0 release of the agentgateway project! This release makes LLM routing more resilient, turns on the Kubernetes AgentgatewayModel API by default, adds zero-configuration cost tracking for common public models, improves OIDC and JWT authentication, and fills important MCP compatibility gaps. It also adds session affinity, per-key local rate limits, graceful draining, and richer OpenTelemetry output. Before upgrading, review the breaking and behavior changes below.
Release v1.6.0-rc.1 · agentgateway/agentgateway

Release v1.6.0-alpha.1 · agentgateway/agentgateway
🎉 Welcome to the 1.6.0-alpha.1 release of the agentgateway project! Agentgateway v1.6.0 is expected in roughly 2 weeks; this is a pre-release build.

1.32.1 - Forward-Proxy TLS, an mcp 2.x Pin, and Collector Health
Release 1.32.1 - Forward-Proxy TLS, an mcp 2.x Pin, and Collector Health October 2026 Upgrading from 1.32.0 This section covers everything you need to know to upgrade from 1.32.0 to 1.32.1. Breaking Changes There are no breaking changes in this release. New Environment Variables No new environment variables in this release. Upgrade Instructions Docker Compose Kubernetes / Helm (EKS) The chart values now carry the 1.32.1 image tags, so rebuild chart dependencies before you upgrade.
1.32.0 - Forward-Proxy Egress, Ingress Hostnames, and a Login Regression Fix
Release 1.32.0 - Forward-Proxy Egress, Ingress Hostnames, and a Login Regression Fix October 2026 Upgrading from 1.31.0 This section covers everything you need to know to upgrade from 1.31.0 to 1.32.0. Breaking Changes There are no breaking changes in this release. Two notes for operators who already export proxy variables. EGRESS_FORWARD_PROXY_ENABLED defaults to false, so exporting HTTP_PROXY or HTTPS_PROXY alone changes nothing and does not enable the new routing.
1.31.0 - Backend Identity, Tool-Level Security, and a Faster Hot Path
Release 1.31.0 - Backend Identity, Tool-Level Security, and a Faster Hot Path September 2026 Upgrading from 1.30.0 This section covers everything you need to know to upgrade from 1.30.0 to 1.31.0. Breaking Changes This release carries more behaviour changes on already-shipped paths than 1.30.0 did. Most come from security fixes that started enforcing a rule the code already described, so a deployment can be relying on the gap without knowing it. 1. basic_header token endpoints no longer receive client_id in the request body.
Pre-draft-1653-head: fix(go-validate): consume BUILD_VERSION and report it at runtime
Every build path already passes BUILD_VERSION — build_and_run.sh (compose --build-arg), scripts/build-images.sh, and the release workflow (github.ref_name on a tag) — but the sidecar's Dockerfile declared no ARG, so Docker silently discarded it and the binary carried no version at all. A sidecar running from :latest was indistinguishable from any other build, on the one service whose whole job is to sit in front of an unchanged Python fallback. That is a bad place to be unable to answer "which build is this".
Pre-rebase-1653-backup: Merge main into feat/go-validate-fastpath-sidecar
Resolves four conflicts, all of them additive except the nginx ones. nginx /validate blocks (3 across two templates): this branch templates the upstream as {{VALIDATE_UPSTREAM_HOST}}:{{VALIDATE_UPSTREAM_PORT}} so the cutover is a single proxy_pass line, while main added proxy_http_version 1.1 in #1644 to stop 502s on ECS Service Connect. Both are required, so both are kept — dropping the latter would reintroduce #1643. terraform variables (root + modules/mcp-gateway): both sides appended new variable blocks at the same point in the file.
Gateway 1.0.0
Gateway 1.0.0 brings OAuth authentication, the unrelated client CLI, expanded MCP interoperability, and more complete profile policies and audit controls. Native discovery, resource templates, sub
Adapter 1.0.0
Superseded by Adapter 1.0.1. The 1.0.0 container omits the CA certificate bundle, which can prevent HTTP/OpenAPI sources from starting. Use 1.0.1, which also corrects the Adapter name and version reported to MCP clients.
Adapter 1.0.1
Fixes HTTP/OpenAPI startup in the minimal Adapter container by including the system CA certificate bundle. No extra certificate mount is needed for public HTTPS endpoints. MCP clients now see the A
Web UI 1.0.0
Web UI 1.0.0 completes the profile, source, and audit workflows for Gateway 1.0.0. Profile connection checks and effective audit policy controls. Resource and prompt catalogs, availability rules, aliases, and prompt argument defaults. Quota and rate-limit controls, notification filters, and advanced profile settings. Revision-safe editing, conflict recovery, preserved drafts, and improved audit pagination. Gateway-backed tenant-token validation and refreshed UI dependencies.

Release v0.44.1 · docker/mcp-gateway
Merge pull request #584 from docker/task/schema-dialect-2020-12 fix: translate pre-2020-12 tool schema dialects to JSON Schema 2020-12
Agent v1.2.3
MCP Gateway Agent v1.2.3 — universal (Apple Silicon and Intel), macOS 26 or later. Installing The app is ad-hoc signed rather than notarized, so the first launch needs one extra step: right-click the app and choose Open, then confirm. macOS remembers the choice. (Or run xattr -dr com.apple.quarantine "/Applications/MCP Gateway Agent.app".) Updates after that install themselves — the quarantine flag is not applied to them. Setting it up Open the app, enter your gateway address, and sign in through the browser.
