One Month into MCP: Building an Interface Between LLMs and Unstructured

The Unstructured MCP Server, initially a prototype, has evolved into a robust interface that connects the Unstructured Platform with various LLM-based tools and agents through the Model Context Protocol (MCP), which standardizes context provision to LLMs. This development now supports over 20 tools for managing sources, destinations, workflows, and jobs, with further integration like Firecrawl for web data sourcing. Lessons learned during its development include the importance of maintaining a balanced number of tools to prevent overwhelming LLMs and the need for a clear input schema to optimize tool usage. Additionally, the server demonstrated the unpredictable creativity of LLMs, such as Claude Desktop autonomously configuring workflows. The project continues to expand with new connectors and optimizations, and interested users can follow its progress on GitHub.
