Crunchbase MCP Server
A Model Context Protocol (MCP) server that provides access to Crunchbase data for AI assistants. This server allows AI assistants to search for companies, get company details, funding information, acquisitions, and people data from Crunchbase.
Features
- Search for companies based on various criteria
- Get detailed information about specific companies
- Retrieve funding rounds for companies
- Get acquisition data
- Search for people associated with companies
Prerequisites
- Node.js (v16 or higher)
- A Crunchbase API key
Installation
- Clone the repository:
bash git clone https://github.com/Cyreslab-AI/crunchbase-mcp-server.git cd crunchbase-mcp-server
- Install dependencies:
bash npm install
- Build the project:
bash npm run build
Configuration
The server requires a Crunchbase API key to function. You can obtain an API key by signing up for the Crunchbase API.
Setting up the API Key
Set the API key as an environment variable:
bash export CRUNCHBASE_API_KEY=your_api_key_here
MCP Configuration
You can use the included setup script to automatically configure the MCP server:
bash
Build the project first
npm run build
Run the setup script
npm run setup
The setup script will:
- Ask for your Crunchbase API key
- Find your MCP settings file (or create a new one)
- Add the Crunchbase MCP server to your settings
Alternatively, you can manually add it to your MCP configuration file:
{ "mcpServers": { "crunchbase": { "command": "node", "args": ["/path/to/crunchbase-mcp-server/build/index.js"], "env": { "CRUNCHBASE_API_KEY": "your_api_key_here" }, "disabled": false, "autoApprove": [] } } }
Usage
Running the Server
Start the server:
bash npm start
For development with automatic reloading:
bash npm run dev

WIKIPEDIA: XMLHttpRequest (XHR) is an API in the form of a JavaScript object whose methods transmit HTTP requests from a web browser to a web server. The methods allow a browser-based application to send requests to the server after page loading is complete, and receive information back. XMLHttpRequest is a component of Ajax programming. Prior to Ajax, hyperlinks and form submissions were the primary mechanisms for interacting with the server, often replacing the current page with another one.
== History == The concept behind XMLHttpRequest was conceived in 2000 by the developers of Microsoft Outlook. The concept was then implemented within the Internet Explorer 5 browser (1999). However, the original syntax did not use the XMLHttpRequest identifier. Instead, the developers used the identifiers ActiveXObject("Msxml2.XMLHTTP") and ActiveXObject("Microsoft.XMLHTTP"). As of Internet Explorer 7 (2006), all browsers support the XMLHttpRequest identifier. The XMLHttpRequest identifier is now the de facto standard in all the major browsers, including Mozilla's Gecko layout engine (2002), Safari 1.2 (2004) and Opera 8.0 (2005).
=== Standards === The World Wide Web Consortium (W3C) published a Working Draft specification for the XMLHttpRequest object on April 5, 2006. On February 25, 2008, the W3C published the Working Draft Level 2 specification. Level 2 added methods to monitor event progress, allow cross-site requests, and handle byte streams. At the end of 2011, the Level 2 specification was absorbed into the original specification. At the end of 2012, the WHATWG took over development and maintains a living document using Web IDL.
== Usage == Generally, sending a request with XMLHttpRequest has several programming steps.
Create an XMLHttpRequest object by calling a constructor: Call the "open" method to specify the request type, identify the relevant resource, and select synchronous or asynchronous operation: For an asynchronous request, set a listener that will be notified when the request's state changes: Initiate the request by calling the "send" method: Respond to state changes in the event listener. If the server sends response data, by default it is captured in the "responseText" property. When the object stops processing the response, it changes to state 4, the "done" state. Aside from these general steps, XMLHttpRequest has many options to control how the request is sent and how the response is processed. Custom header fields can be added to the request to indicate how the server should fulfill it, and data can be uploaded to the server by providing it in the "send" call. The response can be parsed from the JSON format into a readily usable JavaScript object, or processed gradually as it arrives rather than waiting for the entire text. The request can be aborted prematurely or set to fail if not completed in a specified amount of time.
