Frequently Asked Questions About Model Context Protocol (MCP)

What is the Model Context Protocol (MCP)?

MCP is an open standard open-sourced by Anthropic that allows local AI applications (like Claude Desktop, Cursor, and Antigravity) to safely discover and interact with external data sources and developer tools via standardized JSON-RPC protocols. Instead of writing custom API integration code for each LLM, developers install a single MCP server that works across all supported clients.

Where do I save claude_desktop_config.json on my system?

Claude Desktop reads its configuration file from the default application support directory:

• Windows: %APPDATA%\Claude\claude_desktop_config.json (Press Win + R, paste and press Enter)
• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json

How do I use MCP servers in Cursor IDE?

Cursor supports Model Context Protocol servers natively. Open Cursor Settings > Features > MCP and click "Add New MCP Server". You can also create a .cursor/mcp.json file at the root of your project workspace. This allows your coding agent in Cursor Composer to directly query PostgreSQL databases or run browser automation.

Is my sensitive data or API key exposed?

No. PromptStaging executes 100% locally in your volatile browser memory. No form data, database connection strings, or API tokens are ever logged, transmitted, or sent across the network. Always adhere to security best practices by referencing environment variables rather than hardcoding passwords.
