🪄 GitHub 𝗚𝗿𝗮𝗽𝗵𝗤𝗟 & 𝗖𝗼𝗻𝘁𝗲𝘅𝘁 𝗖𝗼𝗻𝘁𝗿𝗼𝗹
This video explores how to handle massive API schemas without overwhelming your AI. We demonstrate how to import the GitHub GraphQL API and use reShapr’s unique filtering and CustomTools features to drastically reduce the "Context Overload" for your LLM and MCP client application.
📝 WHAT’S COVERED
In this demo, we tackle the challenge of a huge GraphQL schema by executing the following:
✅ GitHub GraphQL Import: Fetching the official schema and mapping it to the GitHub backend.
✅ Context Overload Visualization: Demonstrating how a raw import creates a massive tools list that can confuse LLMs.
✅ I/O Filtering: Using the --io flag to filter the schema down to a single specific query (like user) and its related types.
✅ Fine-Tuning with CustomTools: Using a YAML configuration to achieve surgical precision over the tools exposed to the MCP client.
✅ Context Management: Comparing the character count of tool responses to see the reduction in context window usage.

📡 WHY CONTEXT CONTROL?
When you expose a huge API to an LLM, the "noise" (unnecessary tools) consumes tokens and leads to errors. As shown in the demo, reShapr lets you shrink the tools list from thousands of characters to a manageable, highly relevant set.
