Common questions
Is AppScreenshots 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 in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed –, and the latest version (0.1.0) reached the registry 24 days ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.
What can I use instead?
In the same category: Spec Driven Development, Remote Desktop Commander, SuperCollider

AppScreenshots MCP
简体中文 · Client setup · Tools · Troubleshooting
Let your AI agent create editable app screenshot projects, work with your authorized assets, review and correct designs using available client browser tools, then hand off the editor link for website export in AppScreenshots.
Preview service is live. On September 18, 2026, a protocol client completed OAuth, created and edited a two-frame project, opened it in the website editor, and exported two PNGs. Individual Claude Code, Codex, Gemini CLI, Kimi Code, ZCode and ChatGPT integrations have not yet been certified. Until the website's loopback callback fix is deployed, clients using a
127.0.0.1redirect URI may fail authorization; see troubleshooting.
This public repository contains connection examples, a small installation helper, and an optional agent Skill. The MCP server runs within AppScreenshots. Website, authentication, database, billing and rendering backend code remain in their existing private deployment. The helper is not a local stdio server.
Connect the MCP service
Remote Streamable HTTP endpoint:
https://appscreenshots.net/api/mcpChoose your client and follow its OAuth flow. Sign in with your AppScreenshots account, choose projects/assets, and optionally allow new projects. No database credentials or service API keys are required.
Claude Code
claude mcp add --transport http --scope user appscreenshots https://appscreenshots.net/api/mcpOpen /mcp in Claude Code and authorize AppScreenshots.
Codex
codex mcp add appscreenshots --url https://appscreenshots.net/api/mcpcodex mcp login appscreenshots
For Gemini CLI, Kimi Code, ZCode and ChatGPT, see client setup. MCP is sufficient to call the tools; the Skill below provides a reusable design and preview workflow.
Install the optional Skill
Requires Git and Node.js 20+. No npm dependencies or install hooks are used.
git clone https://github.com/horace68/appscreenshots-mcp.gitcd appscreenshots-mcp node bin/appscreenshots.mjs install-skill codex
For Claude Code, replace the last line with:
node bin/appscreenshots.mjs install-skill claudeThe installer copies skills/appscreenshots into ~/.agents/skills/appscreenshots for Codex or ~/.claude/skills/appscreenshots for Claude Code. It refuses to overwrite an existing directory. Restart the agent to discover the Skill, then use $appscreenshots in Codex or /appscreenshots in Claude Code. Connect and authorize MCP separately.
For project-local or other compatible skill hosts, choose the parent skill directory explicitly:
node bin/appscreenshots.mjs install-skill custom --dir /path/to/project/.agents/skills --dry-runnode bin/appscreenshots.mjs install-skill custom --dir /path/to/project/.agents/skills
Use the directory required by your client. The installer does not auto-configure other clients or modify existing MCP settings. To update a customized Skill, compare it with this repository and merge your edits; for a clean update, move the old directory aside and rerun installation. To uninstall, remove only the installed appscreenshots skill directory. Revoke server access separately in website settings.
Connection helper
node bin/appscreenshots.mjs config codexnode bin/appscreenshots.mjs config claude node bin/appscreenshots.mjs config gemini node bin/appscreenshots.mjs config kimi node bin/appscreenshots.mjs doctor
config prints a snippet to merge into existing settings. doctor checks public OAuth discovery, sends no credentials, and exits nonzero if discovery is unavailable. It does not authenticate or test rendering. The npm package name is not published to the npm registry; use this Git repository.
Try a task
Use my authorized screenshots to create an English App Store screenshot project. Pick an available template, keep the headlines short, open the editor with available browser tools, inspect screenshots, correct clipping/cropping/layout issues, then give me the project link so I can export on the website.
Upload screenshots on the website first and authorize the project or individual assets. Chat attachments are not automatically available to MCP. Tool reference explains editing, retries, previews and downloads.
Availability and data
The default flow does not require cloud rendering: MCP saves projects, the agent inspects the website using its own browser tools, and the user exports in the editor. Browser access is supplied by the client, not installed by this Skill. Website login is separate from MCP OAuth. If browser/image tools are unavailable, visual verification remains pending. Project, template and export entitlements still apply. See the browser review guide.
Manage or revoke access in Settings → Connected AI tools. This repository does not implement purchases, deletion, hosted AI generation or app-store publishing. Security and scope.
Development
npm testnpm run check npm pack --dry-run
Tests exercise configuration generation, installation isolation, overwrite protection, CLI failures and discovery diagnostics. CI runs on Linux, macOS and Windows with Node.js 20 and 22. A protocol client has completed the hosted create, editor preview and export flow; individual client integrations and asset upload remain unverified. See the compatibility matrix.
MIT license covers this repository's helper, examples and Skill; it does not grant access to the hosted service or rights to user assets, paid templates or the website backend.
