rmcp 1.3.0 released 2026-03-26 adds:
auth-client-credentials-jwt — JWT-based client credentials auth for MCP serversauth feature was already present in 1.2 (already used in zeph-mcp)
Workspace currently pins rmcp = "1.2" — needs manual bump to "1.3".
Why upgrade:
Action: Change rmcp = "1.2" to rmcp = "1.3" in root Cargo.toml. Verify zeph-mcp builds and MCP client tests pass. Check if auth-client-credentials-jwt feature is worth enabling.
Closes part of #2178 (Zeph-internal MCP auth improvement).
