shareglow-mcp

MCP server for Shareglow: scan link previews, generate Open Graph images, create short links with their own preview, and read click stats from any MCP client.

It is a thin client of the Shareglow REST API (/v1). Your API key is passed straight through, so plan limits and rate limits apply unchanged. The server holds no credentials of its own.

Hosted endpoint

https://mcp.getshareglow.com/mcp
Authorization: Bearer sk_live_...

Transport: Streamable HTTP. Create an API key at https://app.getshareglow.com/developer.

Tools

ToolDescription
scan_urlScan a public web page and report its link-preview (Open Graph / Twitter Card) metadata, previews per platform, and issues with fix suggestions.
generate_og_imageRender a 1200x630 Open Graph image from a template id (see list_templates) and text params such as title and subtitle. Returns the permanent image URL and whether it was cached. Optional exp (Unix seconds, paid plans) makes the signed URL expire.
create_template_from_urlUse AI to design a new OG image template from a website's brand (logo, colors, fonts) taken from a URL. Returns the layout id, the variables to pass, and the extracted brand kit. Counts against the plan's AI quota.
list_templatesList the OG image templates the workspace can render (built-in and custom) with id, name, version and dimensions.
create_short_linkCreate a short link with its own link preview. Optional custom slug and optional A/B variants (title, description, imageUrl or templateId). Returns id, shortUrl and variants.
get_link_statsGet click analytics for a short link by id: totals plus breakdowns by day, country, device, browser and referrer. Optional from/to dates (YYYY-MM-DD).
refresh_previewForce social platforms to re-fetch a page's link preview after you changed its OG tags or image: bumps the og:image cache-buster, re-scrapes Facebook, and returns the LinkedIn Post Inspector link and the X cache note.

Client setup

Claude Code
claude mcp add --transport http shareglow https://mcp.getshareglow.com/mcp \
  --header "Authorization: Bearer sk_live_..."
Claude Desktop

Claude Desktop reaches remote servers through mcp-remote. Add to claude_desktop_config.json:

{
  "mcpServers": {
    "shareglow": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://mcp.getshareglow.com/mcp", "--header", "Authorization:${AUTH}"],
      "env": { "AUTH": "Bearer sk_live_..." }
    }
  }
}

Or skip the remote and use the stdio server below.

Cursor

~/.cursor/mcp.json:

{
  "mcpServers": {
    "shareglow": {
      "url": "https://mcp.getshareglow.com/mcp",
      "headers": { "Authorization": "Bearer sk_live_..." }
    }
  }
}
Local stdio (any client)
{
  "mcpServers": {
    "shareglow": {
      "command": "npx",
      "args": ["-y", "shareglow-mcp"],
      "env": { "SHAREGLOW_API_KEY": "sk_live_..." }
    }
  }
}

The key can also be passed as --api-key sk_live_.... SHAREGLOW_API_URL points the server at another REST base (default https://app.getshareglow.com).

Errors and limits

  • Each tool needs the key scope of its REST call. A key without it gets 403 insufficient_scope.
  • REST 401, 402, 403 and 429 become MCP tool errors (isError: true) that carry the API's message.
  • URLs are validated before forwarding (http/https, no private or local hosts).
  • Tool results are truncated at 20,000 characters. The API key is redacted from every result and error.

Local development

npm install
npm run typecheck
npm test
npm run build
npm run dev          # Streamable HTTP on PORT (default 8791)
npm run dev:worker   # Cloudflare Worker via wrangler dev

Node 22 or newer is required.
