API.market MCP Gateway

Hosted remote MCP server (Streamable HTTP) that lets AI agents discover and call the APIs listed on API.market through five tools: search_apis, get_api_tools, call_api, check_usage and manage_subscription. Authenticates with OAuth 2.1 (authorization code + PKCE S256, dynamic client registration, scope mcp:use) or an x-api-market-key header.
