ABOVO MCP Server

Publish any content to a permanent public web page by sending an email.

No API key. No signup. No authentication required. SMTP is the API.

US Patent No. 10,404,634 — Abovo42 Corporation — Founder: Sean P. Fenlon

How It Works

Send any email to POST@abovo.co and it instantly becomes a public web page. ABOVO replies with your permanent URL within seconds.

URL Patterns

Group Moderation

When you send the first email to a new [groupname]@abovo.co, ABOVO sends you a confirmation email. Click "I accept" to activate the group — you become the moderator. Until confirmed, the group does not appear on ABOVO.co.

MCP Tools

publish_to_web

Publishes content to ABOVO.co by sending an email through a single, server-configured SMTP identity (ABOVO_SMTP_USER). The tool does not publish as the individual end-user or caller — every post originates from the one identity the server is configured with.

Parameters:

• subject (required) — page title
• body (required) — page content (plain text or HTML)
• format (optional, default html) — text or html
• group (optional) — post to a group ([group]@abovo.co) instead of the personal page

Note: This tool does not accept file attachments. The input schema is limited to subject, body, format, and group.

Returns: A confirmation that the email was sent, plus a link to the sender's ABOVO.co page (https://www.abovo.co/{sender}/), which lists all of that sender's posts. It does not return the exact URL of the newly created post — ABOVO.co emails that permanent per-post URL to the sending address separately, after processing. See Experimental — known limitations.

get_abovo_info

Returns information about ABOVO.co capabilities, URL formats, groups, or use cases.

Query values: capabilities, url_format, groups, use_cases, about

Installation & Usage (local stdio)

This server runs locally over stdio — there is no hosted or remote endpoint. Both installation methods below download from this repository's Releases page. Neither one requires an account or a signup anywhere.

Option 1 — Claude Desktop bundle (recommended)

Download abovo-mcp-server-1.1.1.mcpb from the latest release and double-click it.

Claude Desktop opens an install dialog that asks for your email address and your password (or, for Gmail, an App Password). The password is handed to your operating system's credential store — macOS Keychain, Windows Credential Manager, or the Linux Secret Service — and is never written into a configuration file in plain text.

There is nothing else to configure and no dependency install step: the bundle carries a single self-contained Node build.

Option 2 — command line, straight from the release asset

For any MCP client you configure by hand, install the tarball attached to the same release:

npm install -g https://github.com/seanfenlon/abovo-mcp-server/releases/download/v1.1.1/seanfenlon-abovo-mcp-server-1.1.1.tgz

This is a plain URL install — npm fetches the file over HTTPS and never contacts the npm registry, so no npm account or login is involved. It exposes the abovo-mcp-server command, a stdio MCP server:

Claude Desktop (claude_desktop_config.json)

{
  "mcpServers": {
    "abovo": {
      "command": "abovo-mcp-server",
      "env": {
        "ABOVO_SMTP_USER": "you@example.com",
        "ABOVO_SMTP_PASS": "your-app-password"
      }
    }
  }
}

If the client reports that the command was not found, it is not inheriting your shell's PATH — a common situation for GUI applications on macOS. Run which abovo-mcp-server (where abovo-mcp-server on Windows) and put that absolute path in "command" instead.

Environment variables — the bundle installer collects these for you through its dialog; set them yourself only for the command-line install:

Telemetry

This server records lightweight local telemetry, and it is on by default. For each lifecycle or publish event it prints one line to standard error and appends the same line to a JSONL file.

It records coarse metadata only: the event name, a timestamp, the server version, the transport, the content format, and whether the target was a personal page or a group. It never records subjects, message bodies, email addresses, or credentials.

Where the file goes:

• Local stdio install (either the bundle or the tarball): the operating system's temporary directory (abovo-mcp-telemetry.jsonl).
• Otherwise: a logs/ folder relative to the working directory.

You can point it elsewhere with the ABOVO_TELEMETRY_FILE environment variable, or silence it completely by setting ABOVO_TELEMETRY_DISABLED to 1.

Experimental — known limitations

The publish_to_web MCP tool is experimental. Current known limitations:

• No per-caller identity. All posts are sent from a single, server-configured SMTP identity (ABOVO_SMTP_USER). The tool cannot publish as the individual end-user or caller.
• No exact-URL return. The tool returns a link to the sender's general ABOVO.co page, not the permanent URL of the specific new post. ABOVO.co emails that per-post URL to the sending address separately.
• No attachments. The input schema accepts only subject, body, format, and group. File attachments (images, PDFs, other files) cannot be sent through this tool.
• No idempotency. Repeated calls with identical arguments send repeated emails and create duplicate posts. There is no deduplication or idempotency key.
