&mcp Server Information

The &mcp server provides AI assistants with access to public &tag profiles through the Model Context Protocol (MCP). &tags function as identifiers connecting people and companies with publicly available information, preferences, and context.

What is an &tag?

An &tag is like a social media handle but for AI. Each person and company can establish an &tag (examples: &dan or &nike) containing structured information including preferences, interests, professional details, and context designed for AI assistant interpretation.

Installations for AI Assistants

Many AI assistants (Claude, ChatGPT, Gemini, etc.) now support MCP server configuration, primarily for developer endpoints. Only paid AI assistant accounts currently support MCP addition. Reload your app/browser after adding the MCP server.
