Optimizing Developer Workflows with prompts.chat: Integrating 2,000+ System Prompts into Claude Code and MCP

Anyone new to AI has been there: You open ChatGPT or Claude, stare at the blank chat box, and have no idea what to type to get a decent result. prompts.chat was built to solve exactly that. It is a massive, free library of prompt templates, contributed by the community over nearly 4 years.

This guide goes beyond simply introducing the website. You will learn: How to find the right prompt among more than 2,000 options, how to adapt an English prompt into a Vietnamese one tailored to your workflow, how to download the entire repository to your computer, and how to connect prompts.chat directly to Claude Code or other AI tools so you don’t have to open a browser every time you need it.

What is prompts.chat?

prompts.chat is the largest open-source prompt library available today, created in December 2022 by Turkish developer Fatih Kadir Akın (GitHub handle f), originally named Awesome ChatGPT Prompts. The project was later renamed prompts.chat because the prompts work with any AI assistant, not just ChatGPT.[2]

• 171.9k GitHub stars
• CC0 License: Free to use, including for commercial purposes
• $0 Cost: Completely free, no account required

The prompt count corresponds to the line count in the official data file prompts.csv recorded on October 2, 2026; GitHub star count was recorded on the same date.[3]

Why You Should Know About It

• No need to start from scratch: Whether you need an interview assistant, a copyeditor, or an Excel expert, you can find ready-to-use prompts and tweak them in 2 minutes.
• Learn prompt engineering: Reading through dozens of well-crafted prompts will help you grasp the patterns naturally, rather than studying dry theory.
• Permissive licensing: The prompt data is licensed under CC0, meaning it is dedicated to the public domain—you can copy, modify, and even include it in commercial products without asking for permission. The website’s source code is under the MIT license.[2]
• Recognized by the tech community: Two OpenAI co-founders have shared this project, the repo has been featured by GitHub, and it is cited by Harvard and Columbia in their AI usage guides.[2]

What sections does the website have?

Quick tip: You don’t need an account at all to read, search, and copy prompts. An account is only required when you want to save favorite prompts, create your own collections, or contribute new prompts to the community.

How to choose and use prompts from prompts.chat

The nature of a prompt: It is like an assignment brief given to a very smart intern who knows nothing about you yet. The clearer the brief, the more accurate the results.

Most prompts on prompts.chat are designed around role-play: Asking the AI to act as a seasoned expert, clearly defining what it must do and what it should avoid.

Step 1: Search for prompts based on your needs

Open prompts.chat/prompts. Type the job title or task in English into the search box (as the original repository is primarily in English). If you are unsure of the keywords, go to the Categories or Tags section to filter by relevant professional groups.

Step 2: Understanding the Prompt Structure

Most prompts begin with “I want you to act as…”. When reading them, you only need to grasp 2 core elements:

• Professional role: Located at the beginning of the prompt, defining the role of the AI.
• First request: Located at the end of the prompt (in the form of “My first request is…”), which is the specific task you want the AI to handle immediately.

Step 3: Copy and test run

Click the Copy button on the prompt card to save it to your clipboard, then paste it into the chat box of ChatGPT, Claude, or Gemini. You can also click the button to open the AI tool directly to check the results right away.

Pro tip: Try it immediately with a real task you’re currently working on (a difficult email, a product description, or an assignment). Only when handling real-world data will the true effectiveness of the prompt become fully apparent.

Step 4: Treat prompts as drafts to refine

Since the repository is community-contributed, the quality can be inconsistent. Many prompts written in 2022 are now outdated compared to today’s AI models. Treat prompts as drafts to fine-tune, and never paste sensitive information (customer data, passwords, financial details) into public prompts.

Step 5: Add your own context

Append these 3 sentences to the end of the prompt, and the results will be completely different:

• Target audience: “The reader is a small shop owner who is not tech-savvy.”
• Tone of voice: “Write in a friendly tone, use ‘we’ and ‘you’, and avoid technical jargon.”
• Output format: “Return exactly 3 options, maximum 60 words per option, without any introductory text.”

Step 6: Save the modified version to our own collection

If you don’t save your edited prompt, you’ll have to start from scratch next time. Here are three ways to save it—choose whichever works best for you:

• Create a note file (Notes, Google Keep, Notion) named “Our Prompts”, with one entry per prompt.
• Log in to prompts.chat and click save to create a collection directly on the site.
• If you use Claude, send: “Please remember this prompt for us so we can recall it next time.”

Tip: Make the AI ask questions before starting: Add a sentence at the end of the prompt: “Before starting, ask us up to 3 questions to clarify the requirements.” Just this single line yields significantly more accurate results because the AI doesn’t have to guess. You don’t have to open a browser every time you need a prompt. The project releases all data publicly, with 4 ways to access it. The file is about 5.7 MB with over 2,000 lines, so opening it on a phone will be slow. It is recommended to open it on a computer.

Install the prompts.chat Plugin for Claude Code

If you use Claude Code (the coding-focused version of Claude that runs in the command line), the project provides an official plugin. A plugin is an add-on package, just like installing an app on your phone. Once installed, you can search for prompts directly while working, without having to open a browser.[4]

2-Command Installation Guide

1. Open Claude Code (type claude in your Terminal).
2. Paste the first command to add the plugin “marketplace”, press Enter.
3. Paste the second command to install the plugin, press Enter.
4. Exit Claude Code completely (/exit) and reopen it, as plugins only load on startup.

/plugin marketplace add f/prompts.chat
/plugin install prompts.chat@prompts.chat

What to Type After Installation?

The part following the -- flag provides additional filters: --category by category, --tag by tag, and --type by type (text or image). Source: Official plugin documentation.[4]

Connect prompts.chat to AI Apps via MCP

MCP is an open connection standard that allows an AI application to call external data or tools. Simply put: Just like a USB port, plug it in and your AI app can “see” the entire prompt library to search for you automatically, eliminating the need to copy and paste manually.

Easiest Connection Method

1. Open the MCP connection settings in the application you use (Claude Desktop, Cursor, Windsurf… each app places it differently, usually located in Settings under MCP or Connectors).
2. Paste the configuration snippet below. This is the remote version, requiring no additional local installations on your machine.
3. Save and restart the application.
4. Try messaging: “Find a prompt for writing a job application email on prompts.chat.”

{
  "mcpServers": {
    "prompts.chat": {
      "url": "https://prompts.chat/api/mcp"
    }
  }
}

If you want to run it locally directly on your machine (without making network requests every time; requires Node.js to be pre-installed):[5]

{
  "mcpServers": {
    "prompts.chat": {
      "command": "npx",
      "args": [
        "-y",
        "prompts.chat",
        "mcp"
      ]
    }
  }
}

Keep it minimal to avoid performance overhead: Each additional MCP connection enabled occupies space in the AI’s “short-term memory,” slowing it down and consuming more usage quota. Enable only what you actively use, and disable the rest when not needed.

Vietnamese Starter Prompt Pack

The original repository is almost entirely in English and written for international users. I have prepared a set of Vietnamese prompts following the exact 5-component formula from Part 2, crafted in detail just like the professional prompts in the original repo (each prompt there averages around 2,500 characters, clearly defining the scope of work, output format, and constraints), but tailored to the workplace context in Vietnam.

Each prompt comes with pre-set [square brackets] for you to fill in your information, and all end with the line “please ask us up to 3 questions” so the AI can clarify before getting to work. The table below helps you quickly choose the prompt you need.

Below are 8 Vietnamese prompts fully drafted according to the 5-part framework (role, context, task, output format, constraints), each with placeholders ready for your information. Further down is the mcp.json snippet to connect prompts.chat to your AI client. Click the Copy button in each box and paste it directly where you need it.

{
  "mcpServers": {
    "prompts.chat": {
      "url": "https://prompts.chat/api/mcp"
    }
  }
}

If you want to view the original English repository, open the prompt library on prompts.chat directly.

How to use the downloaded file: Extract it, open the bo-prompt-tieng-viet.txt file using Notepad or TextEdit, copy the block you need, and paste it into the chat box. If you are using Claude, you can drag and drop the file directly into the chat window and message: “Please remember this prompt collection; we will call them by name to use later.”

Contribute prompts and build your own library

Submit your prompt

If you have refined a prompt and it works well, you should share it. Go to prompts.chat/prompts/new, log in, and fill in the details. Once approved, your prompt will automatically sync to the GitHub repository, meaning users all over the world downloading it will have your contribution.[2]

• Give it a clear role title, for example, “Tenancy Agreement Reviewer”—avoid generic names.
• Remove all private information before submitting (client names, phone numbers, internal company metrics).
• Keep in mind that submitted prompts are under the CC0 license, meaning you are completely dedicating it to the public domain—anyone can use and modify it.

Build a Custom Prompt Library for Your Company

Does your company want an internal prompt repository without making it public on the internet? The project allows you to self-host your own instance, complete with custom logos, brand colors, and required authentication. This part requires technical expertise, so if you’re not tech-savvy, feel free to forward this section to your IT colleague.

npx prompts.chat new thu-vien-prompt-cua-toi
cd thu-vien-prompt-cua-toi

The installer will prompt you step-by-step for the brand name, colors, authentication method (GitHub, Google, or corporate credentials), and the features you want to enable. The self-hosted version uses a PostgreSQL database.[6]

Learn Prompt Engineering Systematically

The author also wrote an interactive book on prompt engineering with over 28 chapters, ranging from the basics to advanced techniques like chain-of-thought reasoning and building automated assistants. Read for free at The Interactive Book of Prompting.[2]

Notes for Vietnamese Users and Common Mistakes

• English prompts can still yield Vietnamese responses: Keep the original prompt and simply add a final line: “Please respond entirely in Vietnamese”. This approach often produces better results than awkwardly translating the entire prompt into Vietnamese.
• Do not paste sensitive data: Customer information, contracts, account numbers, and internal source code. The prompts you type are processed through the AI provider’s servers, and if you accidentally post a prompt containing sensitive data to prompts.chat, the entire world can read it.
• Beware of “prompt collections” sold online: Many “1,000 professional prompt” packages advertised in online groups are simply downloaded from this repository and repackaged. The original data is completely free; no one has the right to charge you for it.
• You are completely free to use it for commercial purposes: The CC0 license permits commercial use without requiring attribution. However, giving credit is still good practice—it is polite and helps others discover the original source.
• Old prompts meeting new models: Many prompts written in 2022 often include phrases like “do not explain, only respond within a code block”. Modern models are much smarter; feel free to drop these outdated constraints if the output feels forced.

Common Errors

Copied and pasted into ChatGPT, but the output is too generic

The cause is almost always a lack of context. Add 3 sentences from the Adjust the prompt for your specific task section: Who the audience is, what the tone of voice should be, and what format you want the output in.

Opening the prompts.csv file in Excel causes the text to stick together

Excel is misinterpreting the encoding. Open Excel first, go to Data → From Text/CSV, select the file, and then choose UTF-8 encoding with comma as the delimiter. Or more simply: Upload the file to Google Sheets, which detects it automatically.

Command npx not found when typed

Node.js is not installed on your machine. Download the LTS version at nodejs.org, install it, then close and reopen your command line window and try again.

Installed the plugin into Claude Code, but typing the command does nothing

Exit Claude Code completely and reopen it, as plugins are only loaded at startup. Then type a / followed by prompts to see which commands the system suggests.

Connected MCP but the AI says no tools found

Check 3 things: Did you save the correct config file for the app, have you restarted the app, and is the JSON snippet missing any brackets? Re-pasting the sample snippet from Part 7 is the safest bet.

Can’t find the right prompt

Don’t try to find a perfect fit right away. Take the closest prompt and ask the AI to tweak it, or simply use prompt #8 from the starter kit above to make the original prompt your own.

And that’s it. The library is free and always there; the key factor in the results lies in your willingness to tailor the prompt to our specific tasks. Pick a task you’re currently working on today, try a prompt, and leave a comment to tell us how it went.
