When you ask a prompt like 'Show my open PRs' in Cursor, integrated with GitHub MCP, a complex pipeline of AI reasoning is triggered.
The process involves Cursor's AI models interpreting the request, selecting appropriate tools, and utilizing GitHub APIs through the Model Context Protocol (MCP).
The request starts in the Cursor chat interface, which bundles the prompt, chat history, code snippets, and metadata into a payload sent to a cloud model.
Cursor determines the need for a tool, like the list_pull_requests tool from the GitHub MCP server, and collects necessary parameters like repository details and user credentials.
A JSON-RPC request is formatted by Cursor and sent to the GitHub MCP server, which securely interacts with GitHub's API to retrieve pull request data.
The MCP server authenticates with GitHub, fetches open pull requests, and returns structured JSON responses back to Cursor.
Cursor incorporates the tool's response into the prompt for the Language Model (LLM) to convert into a readable format, showing the user their open PRs.
The development cycle continues as Cursor processes user interactions, enabling context-aware intelligence and seamless workflow integration.
This intricate workflow showcases secure access to real services, structured memory use, and tool-enhanced interactions, defining a new paradigm for developer workflows.
Cursor, combined with MCP, creates an AI-driven workflow that enhances developer experiences by providing contextual reasoning and seamless tool integration.
