No SDK API changes since 1.7.2.
Examples:
- Add lazy-auth-server example (#679)
- Publish lazy-auth-server to npm (added to publish workflows)
Also syncs example dependency ranges to ^1.7.0 (output of npm run bump).
Adds an example MCP App server demonstrating lazy (on-demand) OAuth:
the server connects and lists tools without authentication, and only
prompts for auth when a protected tool is called, by responding 401
with a WWW-Authenticate header pointing at protected-resource metadata.
- Public `show_auth_button` app calls the protected `get_secret` tool
via callServerTool; the host runs the OAuth flow on 401 and retries
- Embedded mock authorization server (authorization-code + PKCE,
short-lived HS256 tokens, refresh + session revocation) so the whole
flow runs from a single process
- TTL-scoped endpoint paths (/ttl/<seconds>/mcp) let slow or automated
clients request longer-lived tokens per connection, threaded through
OAuth via RFC 8707 resource indicators
- `elicit_url` / `elicit_by_error` tools demonstrating URL elicitation
