Standardize startup data queries across your team

`get_company_details` pulls verified firmographic data directly into your VS Code Copilot chat. By committing the configuration to your repository, your whole team can query the exact same startup database. No more mismatched developer environments or inconsistent testing data. Your team can also use `get_company_employees` to verify growth metrics during code reviews. Copilot reads the live headcount data to help you write accurate analytics dashboards that your team can trust.

Track VC transactions in VS Code Copilot with this MCP Server

`search_funding_rounds` searches the venture database for specific transaction sizes and dates directly inside your editor. This system lets your team verify financial data structures without leaving the codebase. You write database migrations with the exact payload formats in hand. When you need deeper context, `get_funding_round_details` returns the specific terms of a transaction. Copilot can then help you write the schema definitions to store these details in your production database.

Map venture connections within your workspace

`get_investor_details` retrieves profiles, active investments, and historical checks for venture capital firms. This tool lets your team build features that map investor networks directly inside your application. Your agent handles the heavy lifting of parsing the investor profiles. You can also use `list_investors` to generate seed data for your local testing environment. This ensures your staging database matches the real-world complexity of venture capital networks.
