Plopino MCP Server

plopino

CLI: publish with one command

npx -y plopino publish ./index.html
npx -y plopino publish ./dist --json
npx -y plopino login
npx -y plopino publish ./dist --update https://plopino.com/b/YOUR_BOARD_ID/
npx -y plopino whoami
npx -y plopino logout

login prompts for an email and a hidden password. Create an account on the website first if needed. Login claims available anonymous uploads made with this CLI's saved identity, reports how many were claimed, and saves a session for future uploads. An existing PLOPINO_TOKEN overrides the saved session for publishing. For Google/GitHub-only accounts, use an API token for future uploads; CLI password login requires an account with a password.

Cookies are stored per server origin under ~/.config/plopino/, with owner-only file permissions. Override the directory with PLOPINO_CONFIG_DIR. Keep this directory to retain the ability to claim anonymous uploads. Passwords are never stored. Logging out revokes the session but preserves the anonymous identity. Browser and MCP sessions are separate: logging in on the website alone does not claim CLI uploads.

For non-interactive login, use login --email you@example.com --password-stdin, supplying the password through standard input from your secret manager. Do not pass passwords as command-line arguments. --json gives structured results and errors; errors exit with status 1. Default publishing writes only the URL to stdout and status to stderr.

Directory uploads skip .git, .env*, node_modules, .ssh, .aws, and symbolic links. Other files are included; publish the output directory you intend to share. A single explicitly selected file is uploaded as requested. Symlink inputs are rejected. CLI commands for the same server cannot run concurrently; after a forcibly terminated process, the next command identifies any stale lock to remove once no command is running.

For development before the npm release, replace npx -y plopino with node /path/to/boards/mcp/index.js in the examples above.

MCP

MCP server for Plopino — lets an AI agent publish what it just built and hand back a public link, without the user touching a browser.

agent writes index.html — or has a report / spreadsheet / markdown on disk
   ↓  publish_page / publish_path
https://plopino.com/b/xxxxxxxx/

Documents are first-class: Word (doc/docx), Excel (xls/xlsx) and Markdown render as readable pages, code and data files get syntax-highlighted previews, and images and video display inline. The recipient opens a link; they never download a file.

Tools

Both take an optional update_url: pass a link returned by an earlier publish and that page's content is replaced while the link stays the same. This needs a token (see below).

Publishing is anonymous by default: no account, no configuration, no API key. The returned link is public; without a token the page is kept for a month, with a token it is permanent and can be updated in place.

Anonymous creates also return claimUrl. It is a private browser link for the publisher: open it yourself, sign in, and confirm the claim to keep that page in your account. Do not append it to the public URL or share it with page viewers. JSON output includes it as claimUrl; human output prints it on stderr for CLI publishes and inside the MCP tool result for agent publishes.

Authentication (optional)

Set PLOPINO_TOKEN to publish to your account instead of anonymously. You get private boards, updates that keep the same link, and you are not subject to the anonymous rate limit.

Create a token at plopino.com/b — the panel hands you a ready-made command with the token already in it (the server keeps an encrypted copy, so you can come back for it any time), then:

claude mcp add plopino --env PLOPINO_TOKEN=plp_xxx -- npx -y plopino

Leaving it unset is a supported configuration, not a degraded one. Most users never need a token — the anonymous flow is the product.

Install

Also listed in the official MCP registry as io.github.plopino/plopino-mcp, and on Smithery as an installable bundle.

Anything that speaks stdio MCP works — the server is a plain stdio process, so the only difference between clients is how you register it. All of the below are the clients' own documented forms (verified 2026-09). Wherever you see plp_xxx, paste a token from plopino.com/b — the panel there fills it in for you and lets you pick your client. If your client would rather not run a local process at all, skip to Remote endpoint — same tools, one URL.

Claude Code

claude mcp add plopino -e PLOPINO_TOKEN=plp_xxx -- npx -y plopino

Codex (CLI and IDE extension share ~/.codex/config.toml)

codex mcp add plopino --env PLOPINO_TOKEN=plp_xxx -- npx -y plopino

Gemini CLI

gemini mcp add -e PLOPINO_TOKEN=plp_xxx plopino npx -y plopino

WorkBuddy — ~/.workbuddy/mcp.json (%USERPROFILE%\.workbuddy\mcp.json on Windows; needs WorkBuddy 5.3+), then restart WorkBuddy:

{
  "mcpServers": {
    "plopino": {
      "command": "npx",
      "args": ["-y", "plopino"],
      "env": { "PLOPINO_TOKEN": "plp_xxx" }
    }
  }
}

Cursor — the same JSON in .cursor/mcp.json (project) or ~/.cursor/mcp.json (global). Windsurf — the same JSON in ~/.codeium/windsurf/mcp_config.json. Claude Desktop — the same JSON in claude_desktop_config.json.

VS Code — same idea in .vscode/mcp.json, but the key is servers, not mcpServers:

{
  "servers": {
    "plopino": {
      "command": "npx",
      "args": ["-y", "plopino"],
      "env": { "PLOPINO_TOKEN": "plp_xxx" }
    }
  }
}

No npm? The server also ships as a single self-contained file on the site. Two lines instead of one, but nothing to install:

curl -fsSL https://plopino.com/plopino-mcp.mjs -o "$HOME/.plopino-mcp.mjs"
claude mcp add plopino -e PLOPINO_TOKEN=plp_xxx -- node "$HOME/.plopino-mcp.mjs"

"$HOME/…" is expanded by your shell as you paste, so the absolute path is what gets registered. That matters: MCP clients spawn the server from an arbitrary working directory, so a relative path would break.

Then just ask: "publish this to Plopino", or "give me a link for that page".

Remote endpoint — nothing to install

Everything above runs on your machine. There is also a hosted Streamable HTTP endpoint serving the same tools, for clients that support remote MCP servers and would rather not run a local process at all:

https://plopino.com/mcp

claude mcp add --transport http plopino https://plopino.com/mcp

Any client that accepts a remote server URL takes that same address. Authentication works the same way: send a token as Authorization: Bearer plp_xxx if you have one, and publish anonymously if you don't.

Two differences from the stdio build, both deliberate:

• publish_path is not available remotely. It takes a path on the machine the server runs on — which, remotely, is not your machine. Use publish_files and send the contents.
• The endpoint is stateless: each request is handled on its own, no session to keep alive.

Self-hosted / local

The instance the server publishes to defaults to https://plopino.com. Set PLOPINO_BASE_URL to point at another one — a staging host, or your own deployment:

PLOPINO_BASE_URL=https://plopino.com npx -y plopino

Requirements

• Node 20 or newer (required by the MCP TypeScript SDK v2).
• The only runtime dependency is the MCP SDK.

Development

npm install
npm test        # 路径展开的边界 + 协议握手/工具列表（不需要网络）

To exercise the full publish path, run a Plopino instance and drive the server over stdio against it:

PLOPINO_BASE_URL=https://plopino.com node index.js

stdout is the MCP protocol channel. Anything written there that is not a JSON-RPC message will break the client. All logging must go to stderr — hence console.error everywhere and never console.log.

Privacy Policy

Full policy: https://plopino.com/privacy

• What is collected. Only what publishing requires: the file contents and file names you pass to a tool, the destination URL, and — for anonymous publishes — the requesting IP address (used for the daily rate limit). The MCP server itself collects nothing and sends no telemetry; it runs locally and writes only to stderr.
• How it is used and stored. Uploaded content is stored on Plopino's servers and served from the returned public link. A PLOPINO_TOKEN is stored locally in your MCP client configuration; the server keeps only its SHA-256 hash.
• Third parties. No content or usage data is sold, shared or sent to third parties for advertising. Plopino uses Cloudflare as its CDN/reverse proxy and self-hosted Umami for aggregate, cookieless visit counts.
• Retention. Anonymous uploads are deleted after 30 days; a link can also be removed earlier from the account page. Uploads made with a token are kept until you delete them or the account is closed. Request deletion or report abuse at abuse@plopino.com.
• Contact. abuse@plopino.com (abuse and privacy requests), or https://plopino.com/abuse.

Notes

• publish_path walks directories recursively and skips symbolic links — following them could escape the directory tree and upload files from elsewhere on the machine.
• Anonymous uploads are rate-limited per IP by the server side.
• Nothing is uploaded until a tool is called; the server does no network I/O at startup.
