What is Repo Prompt?

Repo Prompt is a developer tool that helps AI models understand your codebase without wasting tokens on irrelevant code. Its Context Builder analyzes your project structure and selects only the files and functions needed for your specific task, building dense context that fits within model limits. It works with your existing AI subscriptions—Claude MAX, ChatGPT Plus, Gemini—so there are no extra API costs. The MCP server turns Repo Prompt into a backend for Claude Code, Cursor, and Codex, giving them context analysis and discovery they can't do on their own.

Who it's for

• Solo developers who want to get accurate AI assistance without manually copying code snippets or worrying about token limits.
• Teams using AI coding tools who need consistent, relevant context for Claude Code, Cursor, or Codex across multiple projects.
• Developers on a budget who already pay for AI subscriptions and want to maximize their value without incurring additional API costs.

Key features

Context Builder

The Context Builder scans your project and intelligently selects the files and functions most relevant to your current task. It filters out noise—like configuration files, generated code, or unrelated modules—so your AI model gets only what it needs.

MCP Server Integration

The MCP server transforms Repo Prompt into a backend for Claude Code, Cursor, and Codex. These tools gain context analysis and discovery capabilities they can't perform independently, making your AI assistants far more effective.

No Extra API Costs

Repo Prompt works with your existing subscriptions to Claude MAX, ChatGPT Plus, and Gemini. You don't need to pay for additional API tokens or third-party services—just use what you already have.

Token-Efficient Output

By building dense, task-specific context, Repo Prompt ensures your AI model stays within its token limits. This means fewer truncated responses and more complete, useful answers.

What stands out

"Repo Prompt gives your AI the right code context without burning tokens on noise."

This one-liner captures the product's core edge: it doesn't just feed your AI everything—it curates. While other tools dump entire codebases into prompts, Repo Prompt's Context Builder acts like a smart filter, selecting only what's needed. Combined with the MCP server, it extends the capabilities of popular AI coding tools, making them smarter without changing your workflow or budget.

Worth checking out if…

You're a developer who relies on AI coding assistants but finds yourself constantly fighting token limits or getting irrelevant suggestions. If you use Claude Code, Cursor, or Codex and want them to understand your project's structure better, Repo Prompt is a natural fit. It's also ideal if you're cost-conscious and want to get more from your existing AI subscriptions without adding new expenses.
