What is Xircuits MCP Component Library?
The Xircuits MCP Component Library is a collection of visual programming components for building Model Context Protocol (MCP) servers using the Xircuits interface. It provides nodes to create, configure, and run MCP servers, enabling developers to expose data and functionality to LLM applications in a standardized way.
How to use Xircuits MCP Component Library?
Install the library via xircuits install https://github.com/xpressai/xai-mcp or manually clone the repository and run pip install -r requirements.txt. In a Xircuits workflow, drag components onto the canvas to define server capabilities such as tools, resources, and prompts, then connect them to implement logic and run the server.
Key features of Xircuits MCP Component Library
- Server setup components: MCPCreateServer, MCPRunServer
- Start nodes for defining tools, resources, and prompts
- Result setting components for tool, resource, and prompt executions
- Utility components for arguments, progress, images, and messages
- Lifecycle management with on-start and on-shutdown nodes
Use cases of Xircuits MCP Component Library
- Build an MCP server that exposes a calculator tool to LLM applications
- Define resources that provide data through URI patterns
- Create reusable prompt templates for consistent LLM interactions
- Implement server startup and shutdown logic for resource initialization
- Develop custom MCP servers entirely within a visual programming environment
