CompanyProof

Overview

CompanyProof is an MCP server that lets you find legal companies, retrieve their registry profiles, and verify company facts with source evidence. By speaking the Model Context Protocol, it transforms company research into callable tools within your AI assistant, eliminating the need to switch between applications.

The server runs as a remote endpoint at https://companyproof.ai/v2/mcp with no authentication required and nothing to install locally. Current release is v1.2.1.

CompanyProof is listed in the File System category on mcp.site and works with MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. If you maintain CompanyProof, you can claim this listing to verify ownership, earn the Verified badge, and keep information up to date.
