Fluent UI Blazor Plugin

Everything you need to build Blazor applications with the Microsoft Fluent UI Blazor component library, in one install: the fluentui-blazor skill for correct usage patterns, and the official Fluent UI Blazor MCP server for live, version-accurate lookup of components, enums, icons, and documentation.

Installation

copilot plugin install fluentui-blazor@awesome-copilot

Prerequisites

The .NET 10 SDK or later must be installed and dnx available on your PATH.
The plugin starts its bundled MCP server by running dnx Microsoft.FluentUI.AspNetCore.McpServer. The first launch downloads the package from nuget.org.
The MCP server and the component library are published with the same version number, and the server documents the version it was built against. If your project references a different version, ask the agent to run check_project_version — mismatched versions produce documentation that does not match your code.

What's Included

Skills

Skill	Description
`fluentui-blazor`	Guide for using the `Microsoft.FluentUI.AspNetCore.Components` package: mandatory providers, service registration and lifetimes, strongly-typed icons, the `Items`/`OptionText`/`OptionValue` list binding model, the `IDialogService` pattern, toasts, design tokens and theming, and form components. Includes reference files on setup, layout and navigation, data grid, and theming.

MCP server

This plugin includes the fluent-ui-blazor MCP server configured in ./mcp.json, published on NuGet as Microsoft.FluentUI.AspNetCore.McpServer. If the .NET SDK is unavailable, MCP startup will fail.

It gives the agent authoritative, version-aware answers instead of guesses:

Capability	Tools
Components	`list_components`, `search_components`, `get_component_details`, `list_categories`
Enums	`list_enums`, `get_enum_values`, `get_component_enums`
Icons	`search_icons`, `list_all_icon_names`, `get_icon_details`, `get_icon_usage`
Documentation	`list_documentation`, `search_documentation`, `get_documentation_topic`
Versions	`get_version_info`, `check_project_version`
v4 → v5 migration	`get_migration_overview`, `get_migration_guide`, `list_component_migrations`, `get_component_migration`

Why the skill and the MCP server together

They cover different failure modes, and each is weaker alone:

The skill encodes the patterns that models get wrong from training data — the provider components that fail silently when missing, ServiceLifetime.Transient throwing, FluentSelect not behaving like InputSelect, design tokens needing OnAfterRenderAsync. This is judgement, not lookup.
The MCP server supplies the facts that go stale — exact parameter names, enum values, the 142+ component surface, and the icon catalog — looked up in documentation generated at package build time rather than recalled from training data. It serves the library version it was built against, which is why matching versions matters (see Prerequisites).

Installing them as one plugin means a single copilot plugin install gets a working Fluent UI Blazor setup, instead of a skill that names components the agent then has to invent parameters for.
