<Update label="v3.0.1" description="2026-02-20">
**[v3.0.1: Three-covery Mode](https://github.com/PrefectHQ/fastmcp/releases/tag/v3.0.1)**
First patch after 3.0 — mostly smoothing out rough edges discovered in the wild. The big ones: middleware state that wasn't surviving the trip to tool handlers now does, `Tool.from_tool()` accepts callables again, OpenAPI schemas with circular references no longer crash discovery, and decorator overloads now return the correct types in function mode. Also adds `verify_id_token` to OIDCProxy for providers (like some Azure AD configs) that issue opaque access tokens but standard JWT id_tokens.
