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.
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
How it works
1. Subscribe to this server
2. Retrieve your API Token from your Diffbot dashboard
3. Start extracting structured web data from Claude, Cursor, or any MCP client
No more manual copy-pasting or complex web scraping scripts. Your AI acts as your dedicated data engineer and market research analyst.
Who is this for?
- Data Engineers — instantly extract structured data from thousands of URLs using natural language commands
- Market Researchers — search the Knowledge Graph for specific industry signals and company data without leaving your workspace
- Growth Marketers — automate lead enrichment and competitive analysis through simple AI queries

Why CrewAI?
When paired with CrewAI, Diffbot becomes a first-class tool in your multi-agent workflows. Each agent in the crew can call Diffbot tools autonomously, one agent queries data, another analyzes results, a third compiles reports, all orchestrated through Vinkius with zero configuration overhead.
- —
Multi-agent collaboration lets you decompose complex workflows into specialized roles, one agent researches, another analyzes, a third generates reports, each with access to MCP tools
- —
CrewAI's native MCP integration requires zero adapter code: pass Vinkius Edge URL directly in the
mcpsparameter and agents auto-discover every available tool at runtime - —
Built-in task delegation and shared memory mean agents can pass context between steps without manual state management, enabling multi-hop reasoning across tool calls
- —
Sequential and hierarchical crew patterns map naturally to real-world workflows: enumerate subdomains → analyze DNS history → check WHOIS records → compile findings into actionable reports
Diffbot in CrewAI
Diffbot and 3,400+ other MCP servers. One platform. One governance layer.
Teams that connect Diffbot to CrewAI through Vinkius don't need to source, host, or maintain individual MCP servers. Every tool call runs inside a hardened runtime with credential isolation, DLP, and a signed audit chain.

Why teams choose Vinkius for Diffbot in CrewAI
The Diffbot MCP Server runs on Vinkius-managed infrastructure inside AWS — a purpose-built runtime with per-request V8 isolates, Ed25519 signed audit chains, and sub-40ms cold starts. All 12 tools execute in hardened sandboxes optimized for native MCP execution.
Your AI agents in CrewAI only access the data you authorize, with DLP that blocks sensitive information from ever reaching the model, kill switch for instant shutdown, and up to 60% token savings. Enterprise-grade infrastructure, zero maintenance.

Frequently asked questions
How do I find my Diffbot API Token?
Log in to your Diffbot account and navigate to the Dashboard or Manage Tokens section to copy your unique access token.
What is DQL and how can I use it?
DQL (Diffbot Query Language) allows you to filter the Knowledge Graph. Use the search_knowledge_graph tool with queries like type:Organization industries:"AI".
Can I extract comments from articles?
Yes! The extract_article_data tool has an optional discussion parameter. Set it to true to retrieve structured comment threads if available.
How does CrewAI discover and connect to MCP tools?
CrewAI connects to MCP servers lazily. when the crew starts, each agent resolves its MCP URLs and fetches the tool catalog via the standard tools/list method. This means tools are always fresh and reflect the server's current capabilities. No tool schemas need to be hardcoded.
Can different agents in the same crew use different MCP servers?
Yes. Each agent has its own mcps list, so you can assign specific servers to specific roles. For example, a reconnaissance agent might use a domain intelligence server while an analysis agent uses a vulnerability database server.
What happens when an MCP tool call fails during a crew run?
CrewAI wraps tool failures as context for the agent. The LLM receives the error message and can decide to retry with different parameters, fall back to a different tool, or mark the task as partially complete. This resilience is critical for production workflows.
Can CrewAI agents call multiple MCP tools in parallel?
CrewAI agents execute tool calls sequentially within a single reasoning step. However, you can run multiple agents in parallel using process=Process.parallel, each calling different MCP tools concurrently. This is ideal for workflows where separate data sources need to be queried simultaneously.
Can I run CrewAI crews on a schedule (cron)?
Yes. CrewAI crews are standard Python scripts, so you can invoke them via cron, Airflow, Celery, or any task scheduler. The crew.kickoff() method runs synchronously by default, making it straightforward to integrate into existing pipelines.
MCP tools not discovered
Ensure the Edge URL is correct. CrewAI connects lazily when the crew starts. check console output.
Agent not using tools
Make the task description specific. Instead of "do something", say "Use the available tools to list contacts".
Timeout errors
CrewAI has a 10s connection timeout by default. Ensure your network can reach the Edge URL.
Rate limiting or 429 errors
Vinkius enforces per-token rate limits. Check your subscription tier and request quota in the dashboard. Upgrade if you need higher throughput.
