From 217329a78ad7b9d84292d6944f5f71800f4131af Mon Sep 17 00:00:00 2001 From: Pankaj Telang Date: Wed, 14 Jan 2026 09:55:41 -0500 Subject: [PATCH 01/41] Add MCPEmbedding CRD for embedding model deployment in operator MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Introduces a new MCPEmbedding custom resource to deploy HuggingFace embedding models as MCP servers in Kubernetes. This enables semantic search and similarity features for MCP tools and resources. Key Features: - Custom resource definition for embedding model deployments - Integration with HuggingFace text-embeddings-inference - Support for model caching via PersistentVolumeClaims - Flexible resource configuration and pod customization - GroupRef support for organizational grouping - Comprehensive status conditions and phase tracking Components: - MCPEmbedding CRD with validation and webhook support - Controller for managing deployment lifecycle - Generated CRD manifests and Helm chart templates - RBAC permissions for managing embeddings - Example configurations for various use cases This change is based on the original commit by rebasing onto jerm/2026-01-13-optimizer-in-vmcp to remove intermediate commits. 🤖 Generated with [Claude Code](https://claude.com/claude-code)

Convert from Deployment to StatefulSet for better persistent storage support - Add HFTokenSecretRef field for secure HuggingFace token injection from Kubernetes secrets - Use StatefulSet volumeClaimTemplates for model cache PVCs instead of separate PVC creation -

This enables operators to configure headers server-side, removing the burden from clients. This commit adds the core middleware; subsequent commits add RunConfig types, CLI flags, runner wiring, and CRD support. Key design decisions: - RestrictedHeaders blocklist prevents misconfiguration of hop-by-hop, request smuggling, and identity spoofing headers - Authorization is allowed with a warning (valid for static tokens) - Header names are pre-canonicalized at creation time - Supports both factory pattern (thv run) and direct creation (thv proxy) - Header values are never logged, only names at DEBUG level Related: #3316 * Add Forwarded and Http2-Settings to restricted headers Add two headers to the RestrictedHeaders blocklist per review feedback: - Forwarded (RFC 7239): The standardized equivalent of X-Forwarded-* headers, which are already blocked. Omitting it left an identity spoofing gap. - Http2-Settings (RFC 7540 Section 3.2.1): A hop-by-hop header used in HTTP/1.1 to HTTP/2 upgrades. Forwarding it can cause protocol confusion and request smuggling. It is the companion to the already blocked Upgrade header. --- pkg/transport/middleware/header_forward.go | 136 ++++++++++++ .../middleware/header_forward_test.go | 208 ++++++++++++++++++ 2 files

| From b7af76f74561bb579e9190b8cfaf4c3c23baeffb Mon Sep 17 00:00:00 2001 From: Jakub Hrozek Date: Fri, 23 Jan 2026 17:30:09 +0000 Subject: [PATCH 41/41] Add token endpoint handler (#3408) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * Add token endpoint handler Implement POST /oauth/token handler that exchanges authorization codes for access tokens using fosite's access request/response flow. The handler validates the incoming token request, retrieves the stored authorization session, generates JWT access tokens, and supports RFC 8707 resource parameter for audience-restricted tokens targeting specific MCP servers. This handler completes the OAuth 2.0 authorization code flow started by the authorize and callback handlers. When a client presents an authorization code, fosite retrieves the session that was stored during the callback phase - this session contains the user's subject, the upstream token session ID (tsid), and the client ID binding. The token endpoint uses these stored claims to generate the access token, maintaining the link between issued tokens and upstream IDP tokens for later token injection by the proxy middleware. The test infrastructure is extended to properly track authorization code and PKCE sessions across the full authorize→callback→token flow. * Add RFC 8707 audience validation for token endpoint Implement proper validation of the resource parameter in the token endpoint per RFC 8707. Previously, any client-provided resource was blindly granted as the token audience, which was a security risk. Changes: - Add ErrInvalidTarget error for RFC 8707 invalid_target responses - Add ValidateAudienceURI to validate URI format (absolute, no fragment, http/https only) - Add ValidateAudienceAllowed to check resources against an allowlist - Add AllowedAudiences config field to AuthorizationServerParams and AuthorizationServerConfig - Update TokenHandler to validate before granting audience - Secure default: empty AllowedAudiences rejects all resource requests Co-Authored-By: Claude Opus 4.5 --------- Co-authored-by: Claude Opus 4.5 --- pkg/authserver/server/audience.go | 82 ++++++ pkg/authserver/server/audience_test.go | 71 +++++ pkg/authserver/server/handlers/handler.go | 2 +- .../server/handlers/helpers_test.go | 57 +++- pkg/authserver/server/handlers/token.go | 92 ++++++ pkg/authserver/server/handlers/token_test.go | 269 ++++++++++++++++++ pkg/authserver/server/provider.go | 30 +- 7 files changed, 593 insertions(+), 10 deletions(-) create mode 100644 pkg/authserver/server/audience.go create mode 100644 pkg/authserver/server/audience_test.go create mode 100644 pkg/authserver/server/handlers/token.go create mode 100644 pkg/authserver/server/handlers/token_test.go diff --git a/pkg/authserver/server/audience.go b/pkg/authserver/server/audience.go new file mode 100644 index 0000000000..51edbb374f --- /dev/null +++ b/pkg/authserver/server/audience.go @@ -0,0 +1,82 @@ +// SPDX-FileCopyrightText: Copyright 2025 Stacklok, Inc. +// SPDX-License-Identifier: Apache-2.0 + +package server + +import ( + "net/http" + "net/url" + "slices" + + "github.com/ory/fosite" +) + +// ErrInvalidTarget is the RFC 8707 error for invalid or unauthorized resource parameters. +// This error is returned when: +// -
