## Description
Free remote MCP server for publishing self-contained HTML pages and getting public preview links. No account or API key required.

## Tools
Capabilities this server exposes over MCP:

- **get_cordium_info** — Read service capabilities, limits, connection links, and publishing guidance. No project listing.
- **publish_html** — Create a NEW public, immutable HTML page after the user asks to share it. Returns the actual live preview URL. Never include secrets. No editing or replacement. Save the returned one-time deletion secret privately.
- **get_project_info** — Check one known cordium project ID. Returns live status, size, creation time, and preview URL; does not return untrusted HTML or enumerate projects.
- **get_publication_status** — Check queued publication progress. Wait retry_after_seconds plus jitter before polling again.
- **delete_project** — Remove a publication only when the author explicitly requests deletion and supplies the deletion secret. Never expose this secret in URLs. Older publications require administrator removal.

## Documentation

## What cordium does

cordium provides a remote MCP endpoint for publishing self-contained HTML pages. Its core result is a public preview link that can be opened or shared after a page is published. This makes it suitable for agent workflows that generate a complete HTML document and need a reachable preview rather than only a local file or an inline response.

The page content must be self-contained. The service is focused on publishing that HTML as a preview, rather than describing a broader website hosting, deployment, or application backend workflow. Use it when the input is already a complete page that can stand on its own.

## How it works

An MCP client connects to the remote cordium service and makes the page-publishing capability available to an AI agent. The agent supplies self-contained HTML, cordium publishes the page, and the service returns a public preview link. That link can then be used to inspect the rendered result or share the preview with someone else.

The workflow is intentionally small: provide HTML, publish it, and use the resulting URL. No account creation or API key setup is required for the service described here. Because the output is a public link, avoid placing private or sensitive information in pages intended for publication.

## Setup and configuration

cordium is accessed as a remote MCP server. Connection configuration belongs in the MCP-compatible client that will use it; the service does not require an account or API key. The available information identifies the service at `https://cordium.best/`, which is the published source address for the server.

After the remote server is registered with an MCP client, an agent can use its HTML publishing capability. No environment variables, credentials, or local runtime requirements are needed for the stated no-account, no-key workflow.

## Tools and capabilities

- Publish self-contained HTML pages.
- Produce public preview links for published pages.
- Operate as a remote MCP service.
- Accept use without an account or API key.

## Limitations and notes

cordium is designed around self-contained HTML pages and public previews. It should be selected for preview publication rather than treated as a general-purpose deployment platform. Pages sent for publication should be suitable for public access, since the resulting links are public. The service description does not establish features such as private previews, authentication, custom domains, persistence controls, or application hosting, so those requirements should be evaluated separately.
