Frequently asked questions
What is the Model Context Protocol (MCP)?
The Model Context Protocol (MCP) is an open standard developed by Anthropic that provides a unified JSON-RPC interface for LLMs and AI coding assistants (like Claude, Cursor, and Windsurf) to securely connect with local filesystems, databases, APIs, and custom execution environments.
Where do I save the Claude Desktop configuration file?
On macOS, save it to ~/Library/Application Support/Claude/claude_desktop_config.json. On Windows, save it to %APPDATA%\Claude\claude_desktop_config.json. Restart Claude Desktop after saving to discover new servers.
What is the difference between Stdio and SSE transports in MCP?
Stdio launches a local subprocess on your machine and communicates over standard input/output streams. SSE (Server-Sent Events) connects to a remote server over HTTP, making it ideal for cloud-hosted tools (like Cloudflare Workers or Google Cloud Run).
How do I pass API tokens securely to MCP servers?
Use the `env` object in the configuration to provide environment variables (such as GITHUB_PERSONAL_ACCESS_TOKEN or DATABASE_URL). Claude Desktop and Claude Code securely inject these variables into the spawned subprocess environment.
