MCP Setup Guide

Connect any AI agent to 10,000+ APIs in minutes using a single URL. Works with OpenClaw, Claude Code/Desktop, Cursor, Windsurf, Cline — any MCP-compatible AI client.

You need a Zyla API key to use this MCP server Get API Key

Copy & paste this into any AI agent

This single line works with OpenClaw, Claude Code/Desktop, Cursor, Windsurf, Cline — any MCP-compatible AI client. Just paste it into your agent's chat or config:

Create a skill by wrapping this MCP: https://mcp.zylalabs.com/mcp?apikey=YOUR_ZYLA_API_KEY

Your agent will automatically connect to Zyla's MCP server, discover 10,000+ APIs, and be ready to call them. No extra configuration needed.

Not working? See Compatibility & Setup per Client for detailed instructions.

Or just the MCP URL

If your agent asks for just the URL, copy this:

https://mcp.zylalabs.com/mcp?apikey=YOUR_ZYLA_API_KEY

What is MCP?

The Model Context Protocol (MCP) is an open standard that lets AI agents discover and call external tools. Zyla's MCP server turns 10,000+ REST APIs into tools that any AI agent can use — your agent can search the catalog, read API documentation, and execute live API calls, all through natural language.

One URL, all APIs A single MCP endpoint gives your agent access to the entire catalog. No per-API configuration needed.
Your existing API key Authentication is handled automatically. Your Zyla API key is embedded in the URL.
Zero installation No SDKs, no packages, no Docker containers. Just paste the URL and go.

How it works

When your AI agent connects to the Zyla API Hub MCP server, here's what happens behind the scenes:

1
Connect Your AI client connects to mcp.zylalabs.com using your API key. The server advertises the available tools.
2
You ask a question You write something like "Convert 100 USD to EUR". The AI decides which tools to use.
3
Search & discover The agent calls search_catalog to find a currency conversion API, then get_api_info to read its endpoints and parameters.
4
Call the API The agent calls call_api with the right parameters. The MCP server executes the real API call and returns the response.
5
Get your answer The agent formats the response: "100 USD = 92.34 EUR (rate: 0.9234)". All in seconds, fully automated.

Try it out

After connecting, try asking your agent. No need to subscribe to each API first — Zyla API Hub automatically activates a pay-as-you-go plan the first time your agent calls any API:

  • "Convert 100 USD to EUR"
  • "What's the weather in Buenos Aires?"
  • "Validate the email [email protected]"
  • "Search for finance APIs"
  • "Get the BIN info for card 411111"
  • "Translate 'hello world' to Spanish"
  • "Look up the routing number 021000021"
  • "Get a random joke"
  • "What categories of APIs are available?"
  • "Get the IP geolocation for 8.8.8.8"

Available MCP Tools

When connected, your AI agent gets access to these four tools. The agent chooses which to call based on your request:

search_catalog Search across 10,000+ APIs by keyword. Returns matching APIs with their ID, name, description, category, and number of endpoints.
Example
search_catalog({ query: "currency exchange", limit: 5 })
get_api_info Get full documentation for a specific API: every endpoint, all parameters (name, type, required/optional), and example values.
Example
get_api_info({ api_id: 1234 })
call_api Execute a live API call. Pass the API ID, endpoint ID, HTTP method, and parameters. Returns the real response data.
Example
call_api({ api_id: 1234, endpoint_id: 5678, method: "GET", params: { from: "USD", to: "EUR", amount: 100 } })
list_categories List all API categories (Finance, Weather, AI, Sports, Translation, etc.) with the count of APIs in each.
Example
list_categories()

Who is this for?

Developers building AI agents Give your agent access to real-world data — currency rates, weather, email validation, geolocation, and more — without writing custom API integrations.
AI-assisted coding (Cursor, Windsurf, Cline) Query APIs directly from your IDE. Need to test an endpoint or check data? Ask your coding assistant and it calls the API for you.
Claude Desktop & ChatGPT users Turn your AI chat into a universal API client. Ask questions in natural language and get live data from thousands of APIs.
No-code teams No programming required. Connect MCP, ask questions in plain English, and get real data. Ideal for research, analysis, and prototyping.

Compatibility & Setup per Client

Zyla API Hub MCP uses Streamable HTTP (SSE) transport — the server runs in the cloud, so you don't need to install Python, Node.js, or any local runtime. Just provide the URL.

Client How to connect Transport Difficulty
Claude Code Run claude mcp add and paste the URL stdio / http Very easy
Claude Desktop Edit JSON config file and paste the URL stdio / http Easy
OpenClaw Run openclaw mcp add and paste the URL stdio / SSE Very easy
Codex CLI Run codex mcp add and paste the URL stdio / http Very easy
Cursor Edit .cursor/mcp.json in your project stdio Easy
Windsurf Edit JSON config file stdio Easy
Cline (VS Code) Edit JSON config file stdio Easy
ChatGPT Settings → Apps → Advanced → create Connector with the URL SSE / HTTP Medium

Important notes

ChatGPT requires manual setup Unlike Claude Code or OpenClaw, you can't just paste the MCP line into the ChatGPT chat. You need to go to Settings → Apps → Advanced Settings → Developer Mode, create a new Connector/App, and paste the Zyla API Hub MCP URL there. Once configured, you can use it from the chat normally.
Cloud-based — no local runtime needed The MCP server uses SSE (Server-Sent Events) transport, which means it runs entirely in the cloud. You don't need to install Python, Node.js, or Docker on your machine. Your AI agent connects to mcp.zylalabs.com like visiting a website.
Keep your API key private The apikey= parameter in the MCP URL is your private credential. Do not share it publicly or commit it to public repositories. Anyone with your key can use your Zyla API Hub credits. If you think your key was exposed, rotate it from your API Keys page.

FAQs

Is my API key safe? Your key is sent over HTTPS and only used to authenticate calls to the Zyla API Hub. It is never stored by the MCP server — it's passed through on each request.
Can I use this with any API on Zyla? Yes. Any API listed on the marketplace is available through MCP. Your agent will find it via search_catalog or list_categories. You don't need to subscribe manually — when your agent calls an API for the first time, a pay-as-you-go subscription is created automatically.
What if my agent can't connect? Make sure you're using the full URL with your API key: https://mcp.zylalabs.com/mcp?apikey=YOUR_KEY. Restart your AI client after saving the config. If the issue persists, check that your key is active in your API Keys page.
How is this different from calling APIs directly? With MCP, your AI agent handles everything: finding the right API, reading its documentation, building the request, and parsing the response. You just ask a question in natural language.
Do I need to subscribe to each API before using it? No. When your agent calls an API you haven't used before, Zyla API Hub automatically creates a pay-as-you-go subscription for that API. You only pay for what you use — no manual signup per API required. Just connect MCP and start asking questions.
Where can I get my API key? Create an account or log in, then go to your API Keys page to find your API key.
