Summary

LiteLLM 1.102.0-rc.1 exposes registered Agent Skills through a well-known index and can configure Codex and Claude Code to use a gateway key. Its MCP gateway now applies per-user tool permissions to both discovery and execution, while OAuth handling and guardrail failure paths get additional hardening. The release also adds customer-managed KMS keys for virtual-key secrets and routing observability headers. It is installable from PyPI, but remains a release candidate rather than stable GA.

Why it matters
For teams standardizing multiple coding agents behind one gateway, this release joins skill discovery, MCP authorization, secret custody and routing telemetry in the same control plane. The shape is useful for a proof of concept, but production teams should wait for the stable build and test permission-list consistency, spend accounting and guardrail failure behavior during upgrades.
