### 2026-10-20 (score 50)

First indexed and scored.

## MCP tools (16)

### `check_generator_packages` (~47 tokens)

Check existing EasyTdd.Generators references in the loaded solution without changing files. Return proposed upgrades to the tested version. Ask the user to approve specific projects before calling update_generator_packages.

### `generate_fluent_mock_plain` (~130 tokens)

Generate a template-based FluentMock for an interface or abstract class. Generated once, reflects the type's state at time of generation. Use generate_fluent_mock for the auto-updating version.

Input parameters:

- `contextFilePath` (string|null): Path to a file that uses or declares the type; required when typeName is a simple name
- `regenerate` (boolean): Overwrite existing files that have Recreate=true in settings. Default false.
- `typeName` (string, required): Fully qualified type name (e.g. MyApp.IUserService) or simple name when contextFilePath is provided

### `load_solution` (~37 tokens)

Load or reload a solution. Returns the list of project names.

Input parameters:

- `solutionPath` (string, required): Absolute path to the .sln file

### `generate_test_cases` (~120 tokens)

Generate inline test cases for a parameterized test method. Adds a test case attribute to the method and inserts a source method below it in the same file.

Input parameters:

- `contextFilePath` (string|null): Path to the test file; required when typeName is a simple name
- `methodName` (string, required): Method name. For overloads, append param types: Process(int,string)
- `typeName` (string, required): Fully qualified name of the containing type (e.g. MyApp.Tests.MyTests) or simple name when contextFilePath is provided

### `generate_fluent_mock` (~135 tokens)

Generate an incremental FluentMock for an interface or abstract class. The mock wraps Moq with fluent Setup/Verify methods and auto-updates when the target type changes. This is the preferred approach.

Input parameters:

- `contextFilePath` (string|null): Path to a file that uses or declares the type; required when typeName is a simple name
- `regenerate` (boolean): Retained for compatibility. Incremental marker files are never overwritten; delete the marker to recreate it.
- `typeName` (string, required): Fully qualified type name (e.g. MyApp.IUserService) or simple name when contextFilePath is provided

### `get_model` (~89 tokens)

Return the model schema (field names and types) available in Scriban templates for a given generation tool. Use this to verify that a custom template uses only valid field names before or after an upgrade.

Input parameters:

- `toolName` (string, required): MCP tool name: generate_builder, generate_builder_plain, generate_fluent_mock, generate_fluent_mock_plain, generate_test, generate_test_cases, generate_test_cases_external

### `initialize` (~66 tokens)

Initialize EasyTdd for this solution. Creates the .easyTdd folder, writes default settings.json, and deploys default templates. Must be called once before any generation tool. Review the returned settings with the user before generating — key decisions: test framework, project naming conventions, tooling namespaces.

### `update_settings` (~66 tokens)

Merge a partial settings JSON into the current EasyTdd settings. Only provide the fields you want to change. Example: {"Test": {"DefaultTestFramework": "xUnit"}}

Input parameters:

- `partialJson` (string, required): Partial settings JSON to merge. Only provide fields you want to change.

### `generate_builder_plain` (~125 tokens)

Generate a template-based builder for a type. The builder is generated once and reflects the type's state at the time of generation. Use generate_builder for the auto-updating version.

Input parameters:

- `contextFilePath` (string|null): Path to a file that uses or declares the type; required when typeName is a simple name
- `regenerate` (boolean): Overwrite existing files that have Recreate=true in settings. Default false.
- `typeName` (string, required): Fully qualified type name (e.g. MyApp.MyClass) or simple name when contextFilePath is provided

### `customize_template` (~76 tokens)

Copy a default template to CustomTemplates and update settings to use the custom copy. Pass a path from templates_used in a generation tool response. After this call, edit the returned file path directly to customize the template.

Input parameters:

- `templateFilePath` (string, required): Relative template path from templates_used (e.g. defaulttemplates\builder.g.tpl)

### `generate_test` (~118 tokens)

Generate a test class for a type. Creates test doubles (builders/mocks) for dependencies, a subject under test, and test method stubs.

Input parameters:

- `contextFilePath` (string|null): Path to a file that uses or declares the type; required when typeName is a simple name
- `regenerate` (boolean): Overwrite existing files that have Recreate=true in settings. Default false.
- `typeName` (string, required): Fully qualified type name (e.g. MyApp.MyService) or simple name when contextFilePath is provided

### `get_settings` (~32 tokens)

Return the current EasyTdd settings with field descriptions. Use this to show the user what is configured before making changes.

### `upgrade` (~47 tokens)

Upgrade EasyTdd settings and templates to the current installed version. Ask the user for confirmation before calling this tool. Returns a changelog of what changed and lists any custom templates that may need review.

### `generate_test_cases_external` (~147 tokens)

Generate test cases for a parameterized test method in an external class file. Adds a test case attribute to the method, adds a using, and creates a new source class file.

Input parameters:

- `contextFilePath` (string|null): Path to the test file; required when typeName is a simple name
- `methodName` (string, required): Method name. For overloads, append param types: Process(int,string)
- `regenerate` (boolean): Overwrite existing files that have Recreate=true in settings. Default false.
- `typeName` (string, required): Fully qualified name of the containing type (e.g. MyApp.Tests.MyTests) or simple name when contextFilePath is provided

### `generate_builder` (~123 tokens)

Generate an incremental builder for a type. The builder is attribute-driven and auto-updates when the target class changes. This is the preferred builder approach.

Input parameters:

- `contextFilePath` (string|null): Path to a file that uses or declares the type; required when typeName is a simple name
- `regenerate` (boolean): Retained for compatibility. Incremental marker files are never overwritten; delete the marker to recreate it.
- `typeName` (string, required): Fully qualified type name (e.g. MyApp.MyClass) or simple name when contextFilePath is provided

### `update_generator_packages` (~94 tokens)

Update only approved project references to the tested EasyTdd.Generators version. Call check_generator_packages and obtain explicit user approval first. Recheck versions; never downgrade or overwrite shared/central versions.

Input parameters:

- `confirmed` (boolean): Set true only after explicit user approval of these upgrades; false makes no changes.
- `projectFilePaths` (array, required): Absolute project paths returned by check_generator_packages and explicitly approved by the user.

## Common questions

### What is the EasyTdd MCP server?

EasyTdd is an MCP server listed in the public MCP registry as dev.easytdd/easytdd. Generate C# builders, FluentMocks, tests and test cases from your .NET solution. This page covers its NuGet package (EasyTdd.Mcp).

### Is the EasyTdd MCP server safe to use?

EasyTdd scores 65 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 23 October 2026. It declares no install or post-install scripts. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the EasyTdd MCP server expose?

EasyTdd exposes 16 tools: check_generator_packages, generate_fluent_mock_plain, load_solution, generate_test_cases, generate_fluent_mock, and 11 more. Their descriptions and schemas cost roughly 1,452 tokens of context every time the server is loaded.

### Is the EasyTdd MCP server still maintained?

EasyTdd is still listed as active in the MCP registry. We last reached this channel on 23 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the EasyTdd MCP server under?

EasyTdd declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
