Opengraph Io MCP

🚀 OpenGraph MCP Server (og-mcp)

og-mcp is a Model-Context-Protocol (MCP) server that enables AI agents (e.g., Anthropic Claude, Cursor, LangGraph) to access every OpenGraph.io (https://opengraph.io) API endpoint through the standard MCP interface. This allows autonomous agents to utilize OpenGraph.io's capabilities without exposing raw API keys.

🚀 Quick Start

og-mcp is a Model-Context-Protocol (MCP) server that makes every OpenGraph.io (https://opengraph.io) API endpoint available to AI agents (e.g. Anthropic Claude, Cursor, LangGraph) through the standard MCP interface. If you already use OpenGraph.io to unfurl links, scrape HTML, extract article text, or capture screenshots, you can now give the same capabilities to your autonomous agents without exposing raw API keys.

📦 Installation

Global Installation

You can install this package globally via npm:

npm install -g opengraph-io-mcp

Image Generation

The og-mcp server includes powerful AI-driven image generation capabilities, perfect for creating social media cards, architecture diagrams, icons, and more.

Generate Image

Create images from natural language prompts or diagram code. Supported Image Types (kind):

• illustration - General-purpose AI-generated images
• diagram - Technical diagrams from Mermaid, D2, or Vega syntax
• icon - App icons and logos
• social-card - OG images optimized for social sharing
• qr-code - QR codes with optional styling

Preset Aspect Ratios:

• Social: og-image, twitter-card, twitter-post, linkedin-post, facebook-post, instagram-square, instagram-portrait, instagram-story, youtube-thumbnail
• Standard: wide, square, portrait
• Icons: icon-small, icon-medium, icon-large

Style Presets: github-dark, github-light, notion, vercel, linear, stripe, neon-cyber, pastel, minimal-mono, corporate, startup, documentation, technical

Diagram Templates: auth-flow, oauth2-flow, crud-api, microservices, ci-cd, gitflow, database-schema, state-machine, user-journey, cloud-architecture, system-context

Example Usage:

// Generate a social card
generateImage({
  prompt: "A modern tech startup hero image with abstract geometric shapes",
  kind: "social-card",
  aspectRatio: "og-image",
  stylePreset: "vercel",
  brandColors: ["#0070F3", "#000000"]
})

// Generate a diagram from Mermaid syntax
generateImage({
  prompt: "graph TD; A[User] --> B[API]; B --> C[Database]",
  kind: "diagram",
  diagramSyntax: "mermaid",
  stylePreset: "github-dark"
})

Iterate Image

Refine or modify an existing generated image. Use cases:

• Edit specific parts: "change the background to blue"
• Apply style changes: "make it more minimalist"
• Fix issues: "remove the text", "make the icon larger"
• Crop to specific coordinates

Example:

iterateImage({
  sessionId: "uuid-from-generate",
  assetId: "uuid-from-generate",
  prompt: "Change the primary color to #0033A0 and add a subtle drop shadow"
})

Inspect Image Session

Review session details and find asset IDs for iteration. Returns:

• Session metadata (creation time, name, status)
• List of all assets with prompts, toolchains, and status
• Parent-child relationships showing iteration history

Example:

inspectImageSession({
  sessionId: "uuid-from-generate"
})

Export Image Asset

Export a generated image asset by session and asset ID. Returns the image inline as base64 along with metadata (format, dimensions, size). When running locally (stdio transport), you can optionally provide a destinationPath to save the image to disk. On hosted/HTTP transport, the path is ignored and the image is returned inline only.

Examples:

// Inline only (works everywhere)
exportImageAsset({
  sessionId: "uuid-from-generate",
  assetId: "uuid-from-generate"
})

// Save to disk (stdio/local only)
exportImageAsset({
  sessionId: "uuid-from-generate",
  assetId: "uuid-from-generate",
  destinationPath: "/Users/me/project/images/hero.png"
})

How it works

^{Diagram generated with og-mcp's image generation tools}

The og-mcp server acts as a bridge between AI clients (like Claude or other LLMs) and the OpenGraph.io API:

1. AI client makes a tool call to one of the available MCP functions
2. og-mcp server receives the request and formats it for the OpenGraph.io API
3. OpenGraph.io processes the request and returns data
4. og-mcp transforms the response into a format suitable for the AI client
5. AI client receives the structured data ready for use

This abstraction prevents exposing API keys directly to the AI while providing full access to OpenGraph.io capabilities.

Setup and Running

1. Clone this repository
2. Install dependencies:

   npm install
   

3. Build the TypeScript code:

   npm run build
   

4. Start the server:

   npm start
   

The server will run on port 3010 by default (configurable via PORT environment variable).

Configuration

The server requires an OpenGraph.io App ID to function properly. You can provide this in several ways:

1. Using environment variables: Set OPENGRAPH_APP_ID or APP_ID in a .env file or as an environment variable
2. Using command-line arguments with stdio transport: --app-id YOUR_APP_ID
3. When using SSE transport: Include it in the URL as a query parameter (?app_id=YOUR_APP_ID)

Example .env file:

OPENGRAPH_APP_ID=your_app_id_here
# or
APP_ID=your_app_id_here

Transport Options

Stdio Transport (Recommended)

For command-line usage and npm global installation, the server can be run with stdio transport:

npm run start:stdio

You can pass the OpenGraph API key directly via command-line argument:

npm run start:stdio -- --app-id YOUR_APP_ID

When installed globally:

opengraph-io-mcp --app-id YOUR_APP_ID

This mode allows the server to be invoked directly by other applications that use MCP.

HTTP/SSE Transport

This method runs a web server that can be accessed over HTTP and uses SSE for streaming:

npm start

HTTP/SSE Transport (Alternative)

If you prefer running a persistent server instead of stdio:

npm start

Then configure your client to connect to:

http://localhost:3010/sse?app_id=YOUR_OPENGRAPH_APP_ID

Troubleshooting

• If tools aren't showing up, check that the server is running and the URL is correctly configured in Cursor
• Check the server logs for any connection or authorization issues
• Verify that Claude has been instructed to use the specific tools by name
