+### Conformance Tests
+
+The SDK is validated against the [MCP conformance test suite](https://github.com/modelcontextprotocol/conformance) at 0.1.15 version.
+Full details and instructions are in [`conformance-tests/VALIDATION_RESULTS.md`](conformance-tests/VALIDATION_RESULTS.md).

+**Latest results:**
+
+| Suite         | Result                                              |

+| Client        | 🟡 3/4 scenarios, 9/10 checks passed                |
+| Auth (Spring) | 🟡 12/14 scenarios fully passing (98.9% checks)     |
