Explore remote Model Context Protocol servers natively on iPhone and iPad. MCP Explorer connects directly to compatible Streamable HTTP endpoints and gives you a clear, mobile workspace for understanding and inspecting their capabilities: • Discover tools, resources, prompts, and server instructions • Sign in securely with OAuth 2.1 and PKCE • Run real tool calls with forms generated from JSON Schema • Inspect structured results and raw JSON-RPC traffic • Review request history and save useful calls in collections • Keep server configurations and activity separated on your device Security is built in. OAuth tokens and API credentials are stored in iOS Keychain, authorization headers are excluded from traffic logs, and remote connections require HTTPS. MCP Explorer is a native SwiftUI app, not a web wrapper. Requirements: • A compatible remote MCP server using Streamable HTTP • Valid credentials when required by that server Local stdio servers cannot run as child processes on iOS. Expose them through a secure remote endpoint before connecting.
