@stephentoub it seems there are failing McpMetaAttribute unit tests. |
@copilot, please fix the test failing in CI:
Floating-point comparisons need special care. |
Co-authored-by: stephentoub <[email protected]>
Fixed the test by comparing the actual double value (3.14159) instead of the string representation. This avoids floating point precision issues where the serialized value may have additional decimal places. |
Implemented McpMetaAttribute feature with JSON string values:
<see cref="JsonObject"/>
