In this case, landing with a bug or two might be preferable to keeping up with merge conflicts. Added copilot as a reviewer to see if it catches anything -- might not, but worth a shot.
Good stuff!

Pull Request Overview
This PR migrates all internal usage of the MCP crate's ToolError concept to rmcp's ErrorData type. The migration includes both automated conversions using the ErrorData { ... } variant and the preferred ErrorData::new(...) method for new error constructions.
- Migration from
ToolErrorenum toErrorDatastruct across all tool implementations - Updated error handling patterns to use proper error codes from rmcp's
ErrorCodeenum - Conversion of test assertions to check for new error structure

- Error message is incorrect - should say 'must be a number' but the parameter name suggests it should be 'must be required'. This appears to be a copy-paste error from the require_str_parameter function.
format!("The parameter {name} is required"),

Spelling error: 'createion' should be 'creation'.

Using RESOURCE_NOT_FOUND error code for an invalid parameters scenario is semantically incorrect. Should use INVALID_PARAMS instead.
Suggested change
| ErrorCode::RESOURCE_NOT_FOUND, | |
| ErrorCode::INVALID_PARAMS, |

Converts all usages of our internal MCP crate
ToolErrorconcept to rmcp'sErrorDataThere were some conversions which were automated and uses the
ErrorData { ... }variant, which requires providing the message manually as astd::borrow::Cowvs theErrorData::new(...)option which allows strings.Related #3578
