search_companiesLABSCO SUMMARY
Company research that answers back instead of loading.
The value is the chain: a filter turns into a list of companies, a company turns into its rounds and its acquirers, and a name turns into the people around it — without a browser tab per hop.
What it is
An MCP server over the Crunchbase API. It authenticates with your Crunchbase API key and exposes five calls: company search, company detail, funding, acquisitions and people.
What you get
- Companies searched by query, location, category and founding date range
- The detail record for a specific company
- Every funding round a company has raised
- Acquisition data — who bought whom
- The people associated with a company
Requirements
Node.js 16 or higher and a Crunchbase API key — Crunchbase sells API access separately from a Crunchbase login, so get the key from their API signup. Clone, npm install, npm run build; npm run setup will find your MCP settings file and write the server into it for you.
Setup effort
Build from source — git clone https://github.com/Cyreslab-AI/crunchbase-mcp-server.git
USE CASES
01
Building a list of companies worth looking at
Filter by category, location and founding window, and get the matches back as a list you can work down.
02
Working out whether a company is real
Read the detail record, then the funding rounds behind it.
03
Checking who has been buying in a space
Pull acquisitions across the companies on your list and see which names keep appearing on the buying side.
04
Finding the person to write to
Search the people associated with the company before you draft anything.
05
Sizing a market before a pitch
Search the category, then read funding rounds across the results to see where the money went.
