AgentMarket — The App Store for AI Agents

How it works

Three steps. Two minutes. Then your agent handles everything.

Sign up & add credits

Enter your email. Get an API key instantly. Add credits with any card via Stripe.

Add one line of config

Paste the MCP server into your Claude Desktop config. Your agent is now connected.

Your agent takes over

It discovers tools, pays per call, and gets results back. No human approval needed.

List a Tool

Your tool needs a live endpoint that accepts POST requests with JSON. Register it below and agents can start using it immediately.

How to create a tool

1. Write an API that accepts a POST request with JSON input and returns JSON output. Any language works.

2. Deploy it anywhere with a public URL — Vercel, Railway, Render, or any server. Free tiers work fine.

3. Fill out the form below with your endpoint URL. That's it — your tool is live.

Example: a simple tool in Node.js

index.js

import express from 'express';
const app = express();
app.use(express.json());

app.post('/my-tool', async (req, res) => {
  const { query } = req.body;
  // Your logic here
  const result = await doSomething(query);
  res.json({ result });
});

app.listen(process.env.PORT || 3000);

Deploy to Vercel, Railway, or Render. Use the public URL as your Endpoint URL below.

Tool listed! It's live on the marketplace. Agents can find and use it now.

Follow these steps and your Claude will have access to every tool on AgentMarket.

Claude Desktop App

Step 1. Sign up above and copy your buyer API key.

Step 2. Open this file on your computer:

Mac:

~/Library/Application Support/Claude/claude_desktop_config.json

Windows:

%APPDATA%\Claude\claude_desktop_config.json

Step 3. Paste this into the file (replace YOUR_KEY_HERE with your key):

claude_desktop_config.json

{
  "mcpServers": {
    "agentmarket": {
      "command": "npx",
      "args": [
        "mcp-remote",
        "https://agentmarket-production-2204.up.railway.app/mcp",
        "--header",
        "X-Buyer-Key: YOUR_KEY_HERE"
      ]
    }
  }
}

Step 4. Save the file, then fully quit Claude Desktop (Cmd+Q / Alt+F4) and reopen it.

Step 5. Done! Ask Claude anything like "Use AgentMarket to look up Tesla's stock price"

Pass AgentMarket as an MCP server in your API call:

api call

{
  "model": "claude-sonnet-4-6",
  "mcp_servers": [{
    "type": "url",
    "url": "https://agentmarket-production-2204.up.railway.app/mcp",
    "name": "agentmarket",
    "authorization_token": "YOUR_KEY_HERE"
  }],
  "tools": [{
    "type": "mcp_toolset",
    "mcp_server_name": "agentmarket"
  }]
}
