What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Connection: Runs on your computer
Transport: stdio
Category: Other

Install

Pick the AI app you use, then copy the settings.

Before you install

Basic checks: 1 of 1 passed
Runs on your computer with your user’s permissions (files, network, apps).
The registry lists no key to fill in.

You need

npmNode.js installed (for the npx command)

Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "readfirst": {
      "command": "npx",
      "args": [
        "-y",
        "readfirst",
        "mcp"
      ]
    }
  }
}

Run this in your terminal

claude mcp add readfirst -- npx -y readfirst mcp

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "readfirst": {
      "command": "npx",
      "args": [
        "-y",
        "readfirst",
        "mcp"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "readfirst": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "readfirst",
        "mcp"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Common questions

Is Readfirst safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.20.0) reached the registry today.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

What to read and check before you — or your AI agent — change a file.

Coding agents can follow imports. What they don't know is what your team knows: "amounts here are in cents", "this table is read by the mobile app, keep old columns", "run the payment e2e after touching this". readfirst keeps that knowledge in one file next to the code and hands it out, file by file, at the moment someone is about to change something.

No server, no account, no model calls. MIT. It reads your git checkout and .readfirst/map.json.

What it caught

npx readfirst scan   # no map needed: QuerySet/string results thrown away, expect(...).resolves nobody awaits

The hosted version scans for fixed bug shapes taken from real bugs: a result computed and thrown away, a range check with no type check, a secret compared with !==, and more. Run over 44 open-source repositories and checked by hand:

62 bugs in app code, 28 of them low-severity secret comparisons
36 tests that can never fail, every one the same shape: expect(promise).resolves... with no await or return, so the test ends before the assertion runs
the false positives are kept on record too; the counts come after tuning on the same repositories, so read them as "what is there", not as precision

Fixed by the maintainers:

saleor: an "only recalculate what changed" option recalculated every discounted price (saleor/saleor#19984).
wagtail: a superuser who submits a page for moderation got the moderation email about their own submission (wagtail/wagtail#14790).
mealie: a safety filter on households never applied (mealie-recipes/mealie#8964).
n8n: the RabbitMQ node handed back its channel before the queue bindings were made, and a failed bind escaped as an unhandled rejection (n8n-io/n8n#43017).
django-allauth: a provider callback returned a 500 instead of a clean failure on a non-ASCII value; fixed the day it was reported.

Still with their maintainers: a Tandoor filter that never applied (TandoorRecipes/recipes#4917), and findings sent privately to other projects, which stay unnamed until they are fixed.

Start

Any language; needs Node 20+.

npx readfirst init --agent --ci   # a first map, your agents wired to it (Claude Code, Cursor, Codex, Gemini, ...), the PR Action

npx readfirst read # before changing a file: its rules, risks, checks, tests and callers npx readfirst verify # before you finish: the checks pass and nothing the map ties to the change was left out

Commit .readfirst/map.json. Filled maps for real repositories (vercel/ai, cal.com, excalidraw and two more): examples/.

Everything else (Claude Code plugin and hook, MCP for any agent, Cursor rules, the GitHub Action, the map format, audit, find, monorepos, pinning a version): [the guide](https://github.com/jeonghun917/readfirst/blob/main/docs/guide.md).

Hosted

The CLI, hook, MCP server and Action are free and never send your code anywhere. The readfirst-app GitHub App can write the first map for you (free once per account) and, on Pro, keep it in step after merges and comment on pull requests. Details in the guide.
