Feature & Specification Comparison

Specification	A API.market MCP Gateway Developer Tools	Magic MCP 21st-dev Developer Tools
Summary	Proprietary hosted Streamable HTTP MCP gateway for API discovery, operation schemas, API calls, usage checks and subscription management through five tools: search_apis, get_api_tools, call_api, check_usage and manage_subscription. Requires an API.market account with OAuth (recommended) or API-key authentication. Free tiers, paid plans and limits vary by API; API calls and subscription changes may incur charges. OAuth/PKCE and five-tool discovery verified with Claude Code 2.1.281; not every API operation or client has been tested. The public integration repository contains configuration and documentation, not the hosted server implementation. Connect directly to https://api.market/api/mcp/gateway; no local package is required.	Create crafted UI components inspired by the best 21st.dev design engineers.
