- Get complete company profiles with founding dates, headquarters, employee counts, and operating status
- Track funding rounds from Seed to Series D+ with amounts, dates, and investor syndicates
- Analyze acquisition history to understand M&A strategies and consolidation patterns
- Research investors including VC firms, angels, and corporate venture arms with full portfolios
- Find entrepreneurs and executives with detailed career histories and board memberships
- Monitor IPO activity with stock exchange details, ticker symbols, and offering data
- Map investment networks to identify co-investor relationships and deal flow patterns
How it works
- Get your Crunchbase API key from data.crunchbase.com (requires paid license)

Perfect for professionals who need to answer questions like 'Who invested in Stripe's Series B?', 'What companies has Google acquired since 2020?', or 'Which VCs are most active in AI/ML startups?'

Frequently asked questions
Do I need a paid Crunchbase license to use this MCP?
Yes, the Crunchbase API requires a paid license (Starter, Professional, or Enterprise tier). Free accounts have limited access. Your API key (user_key) is provided via email upon license activation. Contact Crunchbase sales at data@crunchbase.com for licensing options.
Can I track real-time funding announcements and new startup launches?
Crunchbase data is updated regularly but not in real-time. Funding rounds appear within days of public announcement. The API provides the most recent data Crunchbase has processed. For real-time monitoring, consider combining this MCP with news API monitoring for immediate PR detection.
Can I search for companies by industry or location instead of name?
This MCP currently supports name-based search. For industry/location filtering, you can search with broad terms and then review company profiles for location and industry details in the detailed results. Advanced filtering by industry vertical, funding stage, or employee count would require the Crunchbase Enterprise API tier with additional query capabilities.
How does LangChain connect to MCP servers?
Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.
Which LangChain agent types work with MCP?
All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
Can I trace MCP tool calls in LangSmith?
Yes. All MCP tool invocations appear as traced steps in LangSmith, showing input parameters, response payloads, latency, and token usage.
