About Diffbot MCP Server
Connect your Diffbot account to any AI agent and take full control of your structured data extraction and knowledge graph research workflows through natural conversation.
Pydantic AI validates every Diffbot tool response against typed schemas, catching data inconsistencies at build time. Connect 12 tools through Vinkius and switch between OpenAI, Anthropic, or Gemini without changing your integration code. full type safety, structured output guarantees, and dependency injection for testable agents.
What you can do
- Web Content Orchestration — Extract structured metadata from any URL programmatically using AI models specialized for articles, products, and discussion threads
- Knowledge Graph Intelligence — Query Diffbot's massive database of billions of entities using DQL to find organization firmographics, people profiles, and market signals
- Entity Enrichment — Programmatically enhance person and company profiles using names or domains to maintain a high-fidelity database of leads and competitors
- Analyze & Identify — Automatically detect the page type of any URL to apply the most accurate extraction model directly through your agent
- Crawl Monitoring — List and monitor active crawling jobs and check your account usage and API status for instant operational reporting
The Diffbot MCP Server exposes 12 tools through the Vinkius. Connect it to Pydantic AI in under two minutes — no API keys to rotate, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.
