lucide-icons-mcp
A Model Context Protocol (MCP) server exposing Lucide React icons as resources and tools for LLMs and agentic applications. Built with Bun and the MCP TypeScript SDK.
What is Lucide?
Lucide is a beautiful & consistent icon toolkit made by the community. It's an open-source icon library that provides over 1,500+ carefully crafted icons in a single, consistent style. Originally forked from Feather Icons, Lucide has grown into one of the most popular icon libraries for modern web development.
What is MCP?
The Model Context Protocol (MCP) is a standard for AI tools to request specific context from sources outside their main training data.
This MCP server allows AI coding assistants and other agentic applications to access information about Lucide React icons, enabling better assistance with icon search, discovery, and implementation.
Features
- 🔍 Icon Search: Search through 1,500+ Lucide icons by name or category
- 📂 Category Browsing: List icons by categories (Design, Communication, Media, etc.)
- 💡 Usage Examples: Get React/JSX code examples for any icon
- 🔧 Icon Information: Detailed information about each icon
- 🚀 MCP Integration: Ready for Claude Desktop and other MCP clients
- 🌐 Dual Mode: HTTP server or stdio-based MCP server
- 📊 Comprehensive Coverage: All Lucide icons with proper JSX usage
Prerequisites
Getting Started (Development)
1. Clone the repository
2. Install Bun (if you don't have it)
Refer to the official Bun installation guide.
After installation, restart your terminal and check:
3. Install dependencies
4. Build the project
This compiles the TypeScript source to JavaScript in the build
directory.
Usage
HTTP Mode
You can run the HTTP server using npx
:
This starts the HTTP server (defaults to port 3000).
Or install globally:
Then run:
Stdio Mode
Local Development
There are two main ways to run the MCP server:
1. HTTP Mode
Suitable for clients that support communication over HTTP.
For development (using Bun):
2. Stdio Mode
Often used for direct integration with tools like Claude Desktop or the MCP Inspector.
For development (using Bun):
Configuration with AI Tools
Example: Claude Desktop
To use this MCP server in Claude Desktop:
- Open your Claude Desktop configuration file:
- Add the server to the
mcpServers
section:
Option A: via npx
(Recommended):
Option B: Pointing directly to the build output:
- Save the file and restart Claude Desktop.
- You should now see the "lucide-icons" server available in Claude's tools panel.

Example Usage
Here's how an AI tool might use this MCP server:
Example 1: Finding Icons
User: "Find me icons related to ArrowRight"
AI tool calls search_icons
:
Response: Lists icons like ArrowRight
Example 2: Getting Usage Examples
User: "Show me how to use the ArrowRight icon"
AI tool calls get_icon_usage_examples
:
Response:
Example 3: Browsing Categories
User: "What design-related icons are available?"
AI tool calls search_categories
:
Then calls list_icons_by_category
":

Testing MCP Locally with Inspector
You can test the MCP server locally using the MCP Inspector.
First, ensure the project is built:
Then launch the Inspector:
This opens the Inspector interface for interactive testing of your MCP server.
