LlmsTxtKit

About

LlmsTxtKit provides the first native C#/.NET implementation for the /llms.txt standard, enabling AI systems to discover and retrieve clean, curated Markdown content from websites. It addresses critical gaps in the .NET ecosystem for llms.txt tooling, solves infrastructure challenges like WAF blocking and rate limiting with intelligent fetching logic, and introduces robust validation mechanisms to build trust in retrieved content. Additionally, it functions as an MCP (Model Context Protocol) server, allowing any MCP-capable AI agent to use its capabilities as tools for real-time, llms.txt-curated content access during inference.

Key Features

• Infrastructure-aware content fetching with retry logic, WAF detection, and structured status reporting
• MCP server for exposing llms.txt capabilities as tools to AI agent systems
• Comprehensive validation against the llms.txt specification, including URL resolution and freshness checks
• 0 GitHub stars
• Programmatic parsing of llms.txt files into strongly-typed .NET objects
• LLM-ready context generation with token budgeting and structured XML section wrapping

Use Cases

• Integrating llms.txt content retrieval and processing into .NET AI applications
• Enabling AI agents (e.g., Claude, GitHub Copilot) to discover and utilize llms.txt-curated web content
• Retrieving clean, validated Markdown for RAG (Retrieval Augmented Generation) systems while navigating web security challenges
