API.market MCP Gateway

API.market MCP Gateway is a hosted Model Context Protocol (MCP) server operated by MagicAPI Inc that gives AI agents and AI-enabled IDEs access to over 590 APIs and 3,580+ tools through a single endpoint. It supports both OAuth and API key authentication, and the setup page allows users to view and copy every configuration without signing in first.

What It Is

The MCP Gateway sits between an AI client — such as Claude, ChatGPT, Codex, Cursor, or VS Code — and the full API.market catalog. Instead of integrating each API individually, a developer adds one MCP server URL (https://api.market/api/mcp/gateway) to their AI app, and the agent can then discover and call any of the listed APIs on demand. The gateway uses the Streamable HTTP transport and supports OAuth (recommended, no API key required) or a traditional API key flow.

What the Agent Unlocks

Once connected, an agent gains access to tools organized across 44 categories, including:

• Image generation — create, upscale, edit, and enhance images with AI
• Video creation — text-to-video, image-to-video, face swap, colorization
• Audio & voice — text-to-speech, voice cloning, transcription, music
• Web search & scraping — search the web, scrape sites, extract data, news
• AI models & LLMs — inference, embeddings, OCR, NLP tasks
• Face & identity — face recognition, ID verification, biometrics, KYC
• Finance & crypto — stock prices, crypto rates, market data
• Maps & location — geocoding, routing, weather, timezone, places
• E-commerce & data — Amazon products, price tracking, reviews
• Email & messaging — send email, SMS, WhatsApp, push notifications
• Web & PDF tools — screenshots, PDF generation, HTML to Markdown
• SEO & analytics — keywords, SERP rankings, backlinks, domain data

Most APIs on the marketplace include free tiers; pay-as-you-go usage draws from a wallet balance.

Connection Setup

The gateway page walks through setup for six clients: Claude (web, desktop, and Cowork), ChatGPT, Codex, Cursor, VS Code, and Claude Code. For OAuth, users open their AI app's connector settings, paste the MCP server URL, and approve access on API.market — no client ID or secret is required because it is registered automatically. API key mode is also available for apps that do not support OAuth. The page notes that OAuth does not bypass API subscriptions or usage charges, and that tool confirmations should be kept enabled.

Platform and Marketplace Context

The MCP Gateway is a feature of API.market, a broader API marketplace operated by MagicAPI Inc. According to the site, the marketplace hosts 590+ APIs, serves 17,400+ developers, and processes 180M+ monthly API calls. The platform also offers in-house AI models (face swap, text-to-image, object removal, hairstyle changer) available for licensing, and a seller program that lets third-party API providers list and monetize their own APIs. Partners listed on the site include API League, BridgeML, Byteplus, AeroDataBox, Pipfeed, and Trueway.

Why It Matters for AI Agent Workflows

Traditional API integration requires separate authentication, documentation review, and SDK setup for each service. The MCP Gateway collapses that into a single MCP server registration, letting an AI agent select and call the right tool at runtime without the developer pre-wiring each integration. This pattern is particularly useful for agentic coding environments and AI IDEs where the agent needs broad, on-demand access to external data and capabilities rather than a fixed set of pre-approved tools.
