The Model Context Protocol (MCP) is a standard that allows agentic models to communicate with external tools and data sources. For research discovery, this means AI can use research tools through natural language requests, automating platform switching and cross-referencing.

Much like software development, research discovery can be framed in terms of layers of abstraction.

At the lowest level of abstraction, researchers search manually and cross-reference by hand.

This manual approach becomes inefficient when tracking multiple research threads or conducting systematic literature reviews. The repetitive nature of searching across platforms, extracting metadata, and cross-referencing information naturally leads to automation through scripting.

Python scripts automate research discovery by handling web requests, parsing responses, and organizing results.

The research tracker demonstrates systematic research discovery built from these types of scripts.

While scripts are faster than manual research, they often fail to automatically collect data due to changing APIs, rate limits, or parsing errors. Without human oversight, scripts may miss relevant results or return incomplete information.

MCP makes these same Python tools accessible to AI systems through natural language.

The AI orchestrates multiple tools, fills information gaps, and reasons about results:

This can be viewed as an additional layer of abstraction above scripting, where the "programming language" is natural language. This follows the Software 3.0 Analogy, where the natural language research direction is the software implementation.

The easiest way to add the Research Tracker MCP is through Hugging Face MCP Settings:

This workflow leverages the Hugging Face MCP server, which is the standard way to use Hugging Face Spaces as MCP tools.
