⁠Crunchbase MCP Server

MCP server wrapper for Crunchbase⁠ — search and retrieve company profiles, funding rounds, investor information, and acquisitions via the Crunchbase API.

⁠What is Crunchbase?

Crunchbase is the leading platform for business intelligence on startups and private companies. This MCP server connects AI assistants to Crunchbase data, enabling searches for company profiles, funding history, investor portfolios, and acquisition records. A Crunchbase API key is required to access the data.

API key required — obtain a Crunchbase API key at data.crunchbase.com⁠.

Tools:

• crunchbase_info — Return status information for the connected Crunchbase MCP server.

⁠Tools Reference

⁠crunchbase_info

Return basic status for the Crunchbase MCP server.

No parameters.

⁠Example Prompts

Here are example prompts you can use with Claude (or any MCP client) when this tool is connected:

• "Search Crunchbase for companies in the cybersecurity space that raised Series B funding in 2024."
• "Look up the funding history for OpenAI on Crunchbase."
• "Find all companies acquired by Cisco in the last three years using Crunchbase data."
• "Use Crunchbase to get investor portfolio details for Andreessen Horowitz."
• "Search Crunchbase for AI startups headquartered in New York with more than $50M raised."
• "Retrieve the company profile and founding team for a specific startup from Crunchbase."

⁠Deploy

⁠Docker Compose (recommended)

docker-compose up -d

⁠Docker Run (stdio mode)

docker run -i --rm hackerdogs/crunchbase-mcp:latest

⁠Docker Run (HTTP streamable mode)

docker run -d -p 8411:8411 \
  -e MCP_TRANSPORT=streamable-http \
  -e MCP_PORT=8411 \
  hackerdogs/crunchbase-mcp:latest

⁠MCP Client Configuration

⁠Stdio mode (default)

Add to your Claude Desktop or Cursor MCP config:

{
  "mcpServers": {
    "crunchbase-mcp": {
      "command": "docker",
      "args": ["run", "-i", "--rm", "-e", "MCP_TRANSPORT", "hackerdogs/crunchbase-mcp:latest"],
      "env": {
        "MCP_TRANSPORT": "stdio"
      }
    }
  }
}

⁠HTTP mode (streamable-http)

First, start the server using Docker Compose or docker run with HTTP mode (see Deploy⁠ above), then point your MCP client at the running server:

{
  "mcpServers": {
    "crunchbase-mcp": {
      "url": "http://localhost:8411/mcp"
    }
  }
}

⁠Environment Variables

⁠Installing in Hackerdogs

The fastest way to get started is through Hackerdogs⁠:

1. Log in to your Hackerdogs account.
2. Go to the Tools Catalog.
3. Search for the tool by name (e.g. "nuclei", "naabu", "julius").
4. Expand the tool card and click Install — you're ready to go.

1. Vendor API key required? Add your key in the config environment variable field before clicking Install. Your key will be encrypted at rest.
2. Enable / Disable the tool anytime from the Enabled Tools page.
3. Need to update a key or parameter? Go to My Tools → toggle Show Decrypted Values → edit → Save.

⁠Build

docker build -t hackerdogs/crunchbase-mcp:latest .

⁠Testing

⁠Automated tests

./test.sh

⁠Test directly with Docker

1. Start the server in HTTP mode:

docker run -d --rm --name crunchbase-mcp-test -p 8411:8411 \
  -e MCP_TRANSPORT=streamable-http \
  hackerdogs/crunchbase-mcp:latest

2. Initialize the MCP session:

SESSION_ID=$(curl -s -D - -X POST http://localhost:8411/mcp \
  -H "Content-Type: application/json" \
  -H "Accept: application/json, text/event-stream" \
  -d '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2024-11-05","capabilities":{},"clientInfo":{"name":"test","version":"0.1"}}}' \
  2>&1 | grep -i mcp-session-id | awk '{print $2}' | tr -d '\r\n')

curl -s -X POST http://localhost:8411/mcp \
  -H "Content-Type: application/json" \
  -H "Accept: application/json, text/event-stream" \
  -H "mcp-session-id: $SESSION_ID" \
  -d '{"jsonrpc":"2.0","method":"notifications/initialized"}'

3. Call a tool:

curl -s -X POST http://localhost:8411/mcp \
  -H "Content-Type: application/json" \
  -H "Accept: application/json, text/event-stream" \
  -H "mcp-session-id: $SESSION_ID" \
  -d '{"jsonrpc":"2.0","id":2,"method":"tools/call","params":{"name":"run_crunchbase","arguments":{"arguments":"--help"}}}'

4. Clean up:

docker stop crunchbase-mcp-test

⁠Running the tool directly (bypassing MCP)

You can run the Crunchbase CLI in the same container by overriding the entrypoint without starting the MCP server.

Show help:

docker run -i --rm --entrypoint crunchbase hackerdogs/crunchbase-mcp:latest --help
