## TL;DR

Here's what you'll learn:
- Get and set up your OpenAI and Composio API keys
- Install the necessary dependencies
- Initialize Composio and create a Tool Router session for Coinmarketcal
- Configure an AI agent that can use Coinmarketcal as a tool
- Run a live chat session where you can ask the agent to perform Coinmarketcal operations

## What is OpenAI Agents SDK?

The OpenAI Agents SDK is a lightweight framework for building AI agents that can use tools and maintain conversation state. It provides a simple interface for creating agents with hosted MCP tool support.
Key features include:
- Hosted MCP Tools: Connect to external services through hosted MCP endpoints
- SQLite Sessions: Persist conversation history across interactions
- Simple API: Clean interface with Agent, Runner, and tool configuration
- Streaming Support: Real-time response streaming for interactive applications

## What is the Coinmarketcal MCP server, and what's possible with it?

The Coinmarketcal MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Coinmarketcal account. It provides structured and secure access to the Coinmarketcal crypto events calendar, so your agent can perform actions like fetching upcoming cryptocurrency events, discovering new project launches, and tracking market-impacting announcements on your behalf.
- Fetch upcoming crypto events: Ask your agent to retrieve a list of scheduled events, announcements, or coin releases that could impact the crypto markets.
- Discover project launches and updates: Stay on top of new token launches, hard forks, or upgrade announcements directly from Coinmarketcal’s trusted community-driven calendar.
- Track market-impacting news: Let your agent monitor important developments and milestone events for specific coins or across the entire crypto ecosystem.
- Stay informed on trending events: Quickly surface the most anticipated or discussed crypto events, enabling smarter trading and investment decisions.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `COINMARKETCAL_LIST_COINS` | List Coins | Tool to retrieve list of all available coins/cryptocurrencies in CoinMarketCal database. Use when you need to fetch coin information including IDs, names, symbols, and event counts. |
| `COINMARKETCAL_LIST_EVENT_CATEGORIES` | List Event Categories | Tool to list all event categories. Use when you need to fetch available event categories. |
| `COINMARKETCAL_LIST_EVENTS` | List Cryptocurrency Events | Tool to retrieve list of cryptocurrency events. Use when you need to fetch upcoming or past crypto events filtered by date range, coins, categories, or other criteria. Note: Cannot retrieve events before 25/11/2017. The can_occur_before field is important as some events may happen before their stated date. |

## Creating MCP Server - Stand-alone vs Composio SDK

The Coinmarketcal MCP server is an implementation of the Model Context Protocol that connects your AI agent to Coinmarketcal. It provides structured and secure access so your agent can perform Coinmarketcal operations on your behalf through a secure, permission-based interface.
With Composio's managed implementation, you don't have to create your own developer app. For production, if you're building an end product, we recommend using your own credentials. The managed server helps you prototype fast and go from 0-1 faster.

## Step-by-step Guide

### 1. Prerequisites

Before starting, make sure you have:
- Composio API Key and OpenAI API Key
- Primary know-how of OpenAI Agents SDK
- A live Coinmarketcal project
- Some knowledge of Python or Typescript

### 1. Getting API Keys for OpenAI and Composio

OpenAI API Key
- Go to the [OpenAI dashboard](https://platform.openai.com/settings/organization/api-keys) and create an API key. You'll need credits to use the models, or you can connect to another model provider.
- Keep the API key safe.
Composio API Key
- Log in to the [Composio dashboard](https://dashboard.composio.dev?utm_source=toolkits&utm_medium=framework_docs).
- Go to Settings and copy your API key.

### 2. Install dependencies

Install the Composio SDK and the OpenAI Agents SDK.
```python
pip install composio_openai_agents openai-agents python-dotenv
```

```typescript
npm install @composio/openai-agents @openai/agents dotenv
```

### 3. Set up environment variables

Create a .env file and add your OpenAI and Composio API keys.
```bash
OPENAI_API_KEY=sk-...your-api-key
COMPOSIO_API_KEY=your-api-key
USER_ID=composio_user@gmail.com
```

### 4. Import dependencies

What's happening:
- You're importing all necessary libraries.
- The Composio and OpenAIAgentsProvider classes are imported to connect your OpenAI agent to Composio tools like Coinmarketcal.
```python
import asyncio
import os
from dotenv import load_dotenv

from composio import Composio
from composio_openai_agents import OpenAIAgentsProvider
from agents import Agent, Runner, HostedMCPTool, SQLiteSession
```

```typescript
import 'dotenv/config';
import { Composio } from '@composio/core';
import { OpenAIAgentsProvider } from '@composio/openai-agents';
import { Agent, hostedMcpTool, run, OpenAIConversationsSession } from '@openai/agents';
import * as readline from 'readline';
```

### 5. Set up the Composio instance

No description provided.
```python
load_dotenv()

api_key = os.getenv("COMPOSIO_API_KEY")
user_id = os.getenv("USER_ID")

if not api_key:
    raise RuntimeError("COMPOSIO_API_KEY is not set. Create a .env file with COMPOSIO_API_KEY=your_key")

# Initialize Composio
composio = Composio(api_key=api_key, provider=OpenAIAgentsProvider())
```

```typescript
dotenv.config();

const composioApiKey = process.env.COMPOSIO_API_KEY;
const userId = process.env.USER_ID;

if (!composioApiKey) {
  throw new Error('COMPOSIO_API_KEY is not set. Create a .env file with COMPOSIO_API_KEY=your_key');
}
if (!userId) {
  throw new Error('USER_ID is not set');
}

// Initialize Composio
const composio = new Composio({
  apiKey: composioApiKey,
  provider: new OpenAIAgentsProvider(),
});
```

### 6. Create a Tool Router session

What is happening:
- You give the Tool Router the user id and the toolkits you want available. Here, it is only coinmarketcal.
- The router checks the user's Coinmarketcal connection and prepares the MCP endpoint.
- The returned session.mcp.url is the MCP URL that your agent will use to access Coinmarketcal.
- This approach keeps things lightweight and lets the agent request Coinmarketcal tools only when needed during the conversation.
```python
# Create a Coinmarketcal Tool Router session
session = composio.create(
    user_id=user_id,
    toolkits=["coinmarketcal"]
)

mcp_url = session.mcp.url
```

```typescript
// Create Tool Router session for Coinmarketcal
const session = await composio.create(userId as string, {
  toolkits: ['coinmarketcal'],
});
const mcpUrl = session.mcp.url;
```

### 7. Configure the agent

No description provided.
```python
# Configure agent with MCP tool
agent = Agent(
    name="Assistant",
    model="gpt-5",
    instructions=(
        "You are a helpful assistant that can access Coinmarketcal. "
        "Help users perform Coinmarketcal operations through natural language."
    ),
    tools=[
        HostedMCPTool(
            tool_config={
                "type": "mcp",
                "server_label": "tool_router",
                "server_url": mcp_url,
                "headers": {"x-api-key": api_key},
                "require_approval": "never",
            }
        )
    ],
)
```

```typescript
// Configure agent with MCP tool
const agent = new Agent({
  name: 'Assistant',
  model: 'gpt-5',
  instructions:
    'You are a helpful assistant that can access Coinmarketcal. Help users perform Coinmarketcal operations through natural language.',
  tools: [
    hostedMcpTool({
      serverLabel: 'tool_router',
      serverUrl: mcpUrl,
      headers: { 'x-api-key': composioApiKey },
      requireApproval: 'never',
    }),
  ],
});
```

### 8. Start chat loop and handle conversation

## Frequently Asked Questions

### What are the differences in Tool Router MCP and Coinmarketcal MCP?

With a standalone Coinmarketcal MCP server, the agents and LLMs can only access a fixed set of Coinmarketcal tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Coinmarketcal and many other apps based on the task at hand, all through a single MCP endpoint.

### Can I use Tool Router MCP with OpenAI Agents SDK?

Yes, you can. OpenAI Agents SDK fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Coinmarketcal tools.

### Can I manage the permissions and scopes for Coinmarketcal while using Tool Router?

Yes, absolutely. You can configure which Coinmarketcal scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

### How safe is my data with Composio Tool Router?

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Coinmarketcal data and credentials are handled as safely as possible.
