Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Let AI agents read and drive a running React Native or Flutter app through Buoy's devtools.
These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.
Pick the AI app you use, then copy the settings.
You need
Which app do you use?
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": {
"buoy-gg": {
"command": "npx",
"args": [
"-y",
"@buoy-gg/mcp"
]
}
}
}Run this in your terminal
claude mcp add buoy-gg -- npx -y @buoy-gg/mcpPaste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json
{
"mcpServers": {
"buoy-gg": {
"command": "npx",
"args": [
"-y",
"@buoy-gg/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.
Paste into .vscode/mcp.json in your project
{
"servers": {
"buoy-gg": {
"type": "stdio",
"command": "npx",
"args": [

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

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
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.
The registry does not list a required key, though some servers ask you to sign in on first use.
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).
The GitHub repo last changed –, and the latest version (7.0.41) reached the registry 40 days ago.

Buoy puts a floating menu in your app. Use it to check web calls, storage and query caches. You can check stores, routes, renders and speed too. Change them while your app runs. Link the same session to Buoy Desktop or MCP. Or use Ask Buoy right in your app.
Flutter has its own setup for debug builds. Capacitor / Ionic (Beta) uses the web tools on iOS and Android. Solid (Beta) works in Solid 1.9 apps built with Vite. Vue and Nuxt (Beta) works in Vue 3.3 and up built with Vite, and in Nuxt 4. Three.js (Beta) works with R3F and plain apps. Use Scene to see and edit 3D objects.
The quickest way in is to let your coding agent do it. Paste the prompt below into Claude Code, Cursor or Codex. It follows buoy.gg/install.md, installs the core plus the tools that match your dependencies, and tells you how to check it on the device.
Agent install prompt
Install Buoy, the in-app devtools for React Native and Expo, in this project.
Read the full instructions first: curl -fsSL https://buoy.gg/install.md Read the raw text, not a summary. If curl is unavailable, use any HTTP tool you have. Ask me to paste the document only if nothing can fetch it.
Do the install yourself: inspect the repo, run the commands, edit the files. Do not hand me steps you can run.
Work out the routine decisions from the repo: package manager, which app to target, where the menu mounts, which Buoy tools match the dependencies already installed. If Buoy is already partly installed, repair and extend it; never add a second mount, provider, or package set.
When instructions conflict, follow this order: what I say here, then the document's rules about which packages exist and what needs my permission, then this project's own constraints, then the rest of the document, then your judgment.
Ask me before: adding a native dependency, opening a browser or creating an account, changing what a production build does beyond what the document specifies, or anything hard to undo. Do not commit.
You are not done when the packages install. Run this project's existing typecheck; add no tooling. Then report what you installed and why, what you skipped and why, every file you changed, what you verified, and the exact steps I take on the device to confirm the menu appears and captures a request.
To install by hand, start with the core and the Network tool, then sign in:
npm install @buoy-gg/core @buoy-gg/network
npx --package=@buoy-gg/core buoy login
Mounting the menu, loading your key and adding more tools are covered in the Quick start. You need a development build and a Free or Pro Buoy account.
Each tool has a short film on its docs page, recorded on a real app.

Buoy Desktop shows your connected tools in desktop panels and lets you switch between devices. The MCP server lets an AI editor read and change the running app. A free account gets the basic MCP, and Pro adds the full MCP. The MCP also runs the Sim Farm. It gives Buoy Optimize many slim iOS sims or Android phones, so your agent can try many speed ideas at once. The Chrome Farm runs many slim Chromes on your web app, so your tests run side by side. Buoy Web lets your AI use Chrome for you, with real clicks. It needs nothing in your app. Desktop and the MCP's app tools need @buoy-gg/external-sync in your app; the Desktop guide covers the connection.
Buoy starts in development builds. Turning it on in a shipped app takes Pro and your own access checks; read the component reference before you do.
