@igniteui/mcp-server

MCP server for Ignite UI — provides AI assistants with component documentation search and retrieval for Angular, React, Blazor, and Web Components.

Ships with a bundled SQLite database containing pre-compressed, LLM-optimized documentation for all Ignite UI components.

Installation

npm install -g @igniteui/mcp-server

Or use directly with npx:

npx @igniteui/mcp-server

Running From Source

In order to run the MCP from this repository, git submodules must be initialized first. The repo already includes the submodule entries, but a fresh clone still needs to fetch them locally.

The blazor/api-docs submodule is required for local API markdown generation for all four platforms (Angular, React, Web Components, and Blazor).

Recommended first-time setup:

cd packages/igniteui-mcp/igniteui-doc-mcp
git submodule update --init blazor/api-docs
npm install
npm run build:docs:all
npm run build

npm run build:docs:all generates the local API markdown artifacts used by the MCP API tools for all four platforms (Angular, React, Web Components, and Blazor). Run it before starting the server.

If you need to refresh submodules to newer upstream commits later, use:

git submodule update --remote --merge

MCP Client Configuration

{
  "mcpServers": {
    "igniteui-cli": {
      "command": "npx",
      "args": ["-y", "igniteui-cli", "mcp"]
    }
  }
}

Cursor

If Ignite UI CLI is globally installed you can configure the MCP like this:

Add to Cursor MCP settings:

{
  "mcpServers": {
    "igniteui-cli": {
      "command": "npx",
      "args": ["-y", "igniteui-cli", "mcp"]
    }
  }
}

Available Tools

All tools require a framework parameter: angular, react, blazor, or webcomponents.

| Tool | Description | |------|-------------| | list_components | List available Ignite UI component docs. Filter by framework and optional keyword match against filename, component name, keywords, or summary. | | get_doc | Return the full markdown content of a specific component doc by name (e.g., grid-editing, accordion). | | search_docs | Full-text search across Ignite UI docs for a specific framework. Returns top 20 results with excerpt snippets. Supports prefix matching (e.g., grid*). | | search_api | Search Ignite UI API entries by keyword, feature name, or partial component name. | | get_api_reference | Return the full API reference for a specific Ignite UI component or class by exact name. | | get_project_setup_guide | Returns setup guides for creating a new Ignite UI project. For Angular/React/Web Components: CLI scaffolding instructions. For Blazor: dotnet new + NuGet setup guide. |

Available Prompts

| Prompt | Description | |--------|-------------| | igniteui-usage-guide | Instructions for using Ignite UI tools — framework detection, documentation lookup, and project setup. |

Framework Detection

The server detects the Ignite UI framework from component prefixes in your code:

| Framework | Prefix | Example | Package | |-----------|--------|---------|---------| | Angular | Igx | IgxGrid, IgxCombo | igniteui-angular | | React | Igr | IgrGrid, IgrCombo | igniteui-react | | Blazor | Igb | IgbGrid, IgbCombo | IgniteUI.Blazor | | Web Components | Igc + Component | IgcGridComponent | igniteui-webcomponents |

File extensions also help: .razor → Blazor, .tsx → React, .ts + .html → Angular or Web Components.

CLI Options

# Local mode (default) — uses bundled SQLite database
igniteui-mcp

# Remote mode — proxies to a backend API
igniteui-mcp --remote https://your-backend-url.com

# Enable debug logging
igniteui-mcp --debug

Environment Variables

| Variable | Description | |----------|-------------| | DB_PATH | Custom path to the SQLite database file | | IGNITEUI_MCP_DOCS_BACKEND_URL | Backend URL (used with --remote flag when no URL argument is provided) |

Modes

Local (default)

Fully self-contained — no network access required. Uses a bundled SQLite database with FTS4 full-text search powered by sql.js (WebAssembly).

When running from a source checkout, make sure you have already run npm run build:docs:all before starting the MCP so the local API markdowns are present.

Remote

Proxies documentation requests to a backend API. Requires the --remote flag with a URL argument:

igniteui-mcp --remote https://your-backend-url.com

Or provide the URL via environment variable:

IGNITEUI_MCP_DOCS_BACKEND_URL=https://your-backend-url.com igniteui-mcp --remote
