About Diffbot MCP Server
Connect your Diffbot account to any AI agent and take full control of your automated web data extraction through natural conversation.
LangChain's ecosystem of 500+ components combines seamlessly with Diffbot through native MCP adapters. Connect 10 tools via Vinkius and use ReAct agents, Plan-and-Execute strategies, or custom agent architectures. with LangSmith tracing giving full visibility into every tool call, latency, and token cost.
What you can do
- Automated Page Classification — Use the Analyze API to automatically determine if a page is an article, product, or list and extract structured data natively
- Article Extraction — Extract news, blog, or article content into clean HTML and plain text, identifying authors, dates, and categorical classifications limitlessly
- E-commerce Intelligence — Capture structured product details including precise pricing, brand mappings, SKU, and specifications across any web boundary
- Media & Social Auditing — Extract primary images and embedded video metadata, or analyze forum threads and reviews with automated sentiment scoring
- List & Search Scraping — Identify bounded directories and search results on any page to extract arrays of item titles and links strictly
- Job Posting Analysis — Retrieve explicitly mapped job titles, employers, and salary vectors from recruitment pages to monitor market trends
- Custom Rule Execution — Execute user-defined custom extraction logic by bridging raw URLs to your trained Diffbot dashboard rulesets
