Pull request overview
Updates ToolHive documentation to describe vMCP’s embedded authorization server capabilities (including multi-upstream flows) and how upstream tokens can be forwarded/exchanged for backend authentication, plus adds a Redis Sentinel session storage guide.
Changes:
- Document vMCP “upstream token injection” (
upstreamInject) and token exchange with upstream subject tokens (subjectProviderName). - Add embedded authorization server documentation for vMCP (flow, differences vs MCPServer, config examples, and end-to-end walkthrough).
- Add a new Redis Sentinel session storage tutorial and cross-link it from related docs/sidebars.

Add a new how-to guide at docs/toolhive/guides-k8s/redis-session-storage.mdx that walks through deploying Redis Sentinel as the session storage backend for the embedded authorization server. The guide uses self-contained Kubernetes manifests instead of the Bitnami Helm chart, which Broadcom moved behind a paid subscription in August 2025. No maintained, freely available Helm chart with Sentinel support exists as a replacement, so the manifests are provided inline. Also adds TLS configuration documentation for Redis connections (both master and Sentinel), updates the auth-k8s guide's session storage snippet for consistency, and resolves a merge conflict in backend-auth.mdx.

Replace <REDIS_ACL_PASSWORD> with YOUR_REDIS_ACL_PASSWORD (no angle brackets) to avoid confusing ><PLACEHOLDER> syntax in Redis ACL entries. Remove unused vercel.json redirect since the page was never published at the old integrations/ path. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
