About Plopino
Plopino is a publishing service with a CLI and MCP server for agents that need to share generated pages or local files. It renders common documents as readable pages and can replace published content while keeping its URL.
Key features
- 01Publish generated content or local paths
- 02Render documents as readable pages
- 03Preview code, data, images, and video
- 04Update content without changing its link
- 05Anonymous publishing or account publishing
Use cases
- 01Share an agent-generated HTML page
- 02Publish a report or spreadsheet from disk
- 03Revise a published page while preserving its URL
MCP support
The MCP server exposes `publish_page`, `publish_path`, and `publish_files` for publishing content. It supports local stdio and a hosted HTTP endpoint; remote use provides `publish_files` instead of local-path access.
Configuration
Local server config is the same for every client. Copy it into your client’s MCP config file.
Tools

| Parameter | Type | Required | Description |
|---|---|---|---|
| content | string | Yes | The complete content of the file, as a string. With the default filename this is a self-contained HTML document including the <html> tag — relative references to local files will not resolve, so use publish_path when the page needs sibling files (CSS, JS, images). |
| filename | string | No | What to name the file — this decides how the content is rendered, so get it right rather than renaming Markdown to .html. Defaults to "index.html". Use "report.md", "data.csv", "query.sql" and so on; subdirectories work too ("reports/q3.md"). Only text can be sent as a string — binary formats (docx, xlsx, pdf) must go through publish_path. |
| update_url | string | No | A URL returned by an earlier publish. When given, the content of that page is replaced and the link stays the same. Requires the server to be configured with a Plopino token. |
Details
From the project READMEplopino
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 as unencrypted JSON per server origin under ~/.config/plopino/.
The directory is created with mode 0700 and cookie files are written with 0600;
this restricts access to your OS user but is not encryption. 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 saved account session but preserves the anonymous
identity; log out before handing a shared OS account to someone else. Browser and MCP
sessions are separate: logging in on the website alone does not claim CLI uploads.
For non-interactive login, use login --email [email protected] --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.
Both CLI and MCP 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, so never select
credentials or other secrets. 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
| Tool | Use it when |
|---|---|
publish_page | You have the content as a string — generated HTML, or a Markdown / CSV / code document. The filename decides how it renders: leave it at index.html for a page, pass report.md and it renders as a document. |
publish_path | The page needs sibling files (CSS, JS, images), or you are sharing something that is already on disk — including any document, and including binary formats (docx, xlsx, pdf) that cannot be sent as a string. Point it at a directory and the structure is preserved — no need to zip first. |
publish_files | Remote endpoint only. Same job as publish_path for clients that cannot hand over a local path: you send the file contents inline (a relative path plus its content, per entry). |
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.
The stdio MCP server reuses the CLI's per-origin anonymous cookie in
~/.config/plopino/ (override with PLOPINO_CONFIG_DIR). Repeated publishes and MCP restarts
therefore keep the same anonymous identity, and plopino login can claim those uploads. MCP
does not use the saved CLI login session; account publishing and updates still require
PLOPINO_TOKEN.
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.
Claude Code plugin
This repository is also a Claude Code plugin marketplace:
claude plugin marketplace add plopino/plopino-mcp
claude plugin install plopino@plopino
The plugin connects to Plopino's remote MCP endpoint, so it works without a local Node process. A token is optional; leave it empty to publish anonymously.
OpenAI Codex / ChatGPT plugin
codex-plugin/ is the OpenAI-format package and .agents/plugins/marketplace.json is
its Codex marketplace entry:
codex plugin marketplace add plopino/plopino-mcp
codex plugin add plopino@plopino
It uses the remote MCP endpoint with mixed authentication: anonymous by default, or Plopino OAuth 2.1 (DCR + PKCE) for account publishing and in-place updates. The same folder is the single-plugin-root package for the OpenAI directory ZIP submission.
Claude Desktop extension
Download the latest plopino.mcpb,
then open it or drag it into Claude Desktop. This is the local stdio server, with an optional
PLOPINO_TOKEN in the extension settings.
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_pathis not available remotely. It takes a path on the machine the server runs on — which, remotely, is not your machine. Usepublish_filesand 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.erroreverywhere and neverconsole.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 logs only to stderr. Anonymous publishing writes the local identity cookie described above.
- How it is used and stored. Uploaded content is stored on Plopino's servers and served
from the returned public link. A
PLOPINO_TOKENis 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 [email protected].
- Contact. [email protected] (abuse and privacy requests), or https://plopino.com/abuse.
Notes
publish_pathwalks 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.

New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
