What is the Api ninjas MCP server, and what's possible with it?

The Api ninjas MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Api ninjas account. It provides structured and secure access to a wide array of real-time data APIs, so your agent can perform actions like fetching financial data, generating barcodes, validating emails, and looking up domains on your behalf.

  • Fetch live financial and crypto data: Instantly retrieve up-to-date prices for stocks, commodities, ETFs, and cryptocurrencies, or access earnings calendars and transcripts for informed decision-making.
  • Barcode generation on demand: Have your agent create barcode images for custom data or text, perfect for inventory, tickets, or quick sharing of encoded information.
  • Email validation and security checks: Automatically check if an email address is disposable or risky before engaging users or sending communications.
  • Bank and payment info lookup: Look up bank details using BIN numbers, helping with payment processing, fraud detection, or financial analysis.
  • Domain and DNS diagnostics: Let your agent perform DNS lookups to fetch domain records, aiding in troubleshooting or technical audits quickly and efficiently.

Connecting Api ninjas via Composio SDK

Composio SDK is the underlying tech that powers Rube. It's a universal gateway that does everything Rube does but with much more programmatic control. You can programmatically generate an MCP URL with the app you need (here Api ninjas) for even more tool search precision. It's secure and reliable.

How the Composio SDK works

The Composio SDK follows a three-phase workflow:

  1. Discovery: Searches for tools matching your task and returns relevant toolkits with their details.
  2. Authentication: Checks for active connections. If missing, creates an auth config and returns a connection URL via Auth Link.
  3. Execution: Executes the action using the authenticated connection.

Step-by-step Guide

Prerequisites

Before starting, make sure you have:
  • Claude Pro, Max, or API billing enabled Anthropic account
  • Composio API Key
  • A Api ninjas account
  • Basic knowledge of Python or TypeScript

Install Claude Code

bash
# macOS, Linux, WSL
curl -fsSL https://claude.ai/install.sh | bash

# Windows PowerShell
irm https://claude.ai/install.ps1 | iex

# Windows CMD
curl -fsSL https://claude.ai/install.cmd -o install.cmd && install.cmd && del install.cmd

To install Claude Code, use one of the following methods based on your operating system:

Set up Claude Code

bash
cd your-project-folder
claude

Open a terminal, go to your project folder, and start Claude Code:

  • Claude Code will open in your terminal
  • Follow the prompts to sign in with your Anthropic account
  • Complete the authentication flow
  • Once authenticated, you can start using Claude Code
Claude Code initial setup showing sign-in prompt
Claude Code terminal after successful login

Set up environment variables

bash
COMPOSIO_API_KEY=your_composio_api_key_here
USER_ID=your_user_id_here

Create a .env file in your project root with the following variables:

  • COMPOSIO_API_KEY authenticates with Composio (get it from Composio dashboard)
  • USER_ID identifies the user for session management (use any unique identifier)

Install Composio library

pip install composio-core python-dotenv

Install the Composio Python library to create MCP sessions.

  • composio-core provides the core Composio functionality
  • python-dotenv loads environment variables from your .env file

Generate Composio MCP URL

import os
from composio import Composio
from dotenv import load_dotenv

load_dotenv()

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

composio_client = Composio(api_key=COMPOSIO_API_KEY)

composio_session = composio_client.create(
    user_id=USER_ID,
    toolkits=["api_ninjas"],
)

COMPOSIO_MCP_URL = composio_session.mcp.url

print(f"MCP URL: {COMPOSIO_MCP_URL}")
print(f"\nUse this command to add to Claude Code:")
print(f'claude mcp add --transport http api_ninjas-composio "{COMPOSIO_MCP_URL}" --headers "X-API-Key:{COMPOSIO_API_KEY}"')

Create a script to generate a Composio MCP URL for Api ninjas. This URL will be used to connect Claude Code to Api ninjas.

What's happening:
  • We import the Composio client and load environment variables
  • Create a Composio instance with your API key
  • Call create() to create a Tool Router session for Api ninjas
  • The returned mcp.url is the MCP server URL that Claude Code will use
  • The script prints this URL so you can copy it

Run the script and copy the MCP URL

python generate_mcp_url.py

Run your Python script to generate the MCP URL.

  • The script connects to Composio and creates a Tool Router session
  • It prints the MCP URL and the exact command you need to run
  • Copy the entire claude mcp add command from the output

Add Api ninjas MCP to Claude Code

bash
claude mcp add --transport http api_ninjas-composio "YOUR_MCP_URL_HERE" --headers "X-API-Key:YOUR_COMPOSIO_API_KEY"

# Then restart Claude Code
exit
claude

In your terminal, add the MCP server using the command from the previous step. The command format is:

  • claude mcp add registers a new MCP server with Claude Code
  • --transport http specifies that this is an HTTP-based MCP server
  • The server name (api_ninjas-composio) is how you'll reference it
  • The URL points to your Composio Tool Router session
  • --headers includes your Composio API key for authentication

After running the command, close the current Claude Code session and start a new one for the changes to take effect.

Verify the installation

bash
claude mcp list

Check that your Api ninjas MCP server is properly configured.

  • This command lists all MCP servers registered with Claude Code
  • You should see your api_ninjas-composio entry in the list
  • This confirms that Claude Code can now access Api ninjas tools

If everything is wired up, you should see your api_ninjas-composio entry listed:

Claude Code MCP list showing the toolkit MCP server

Authenticate Api ninjas

The first time you try to use Api ninjas tools, you'll be prompted to authenticate.

  • Claude Code will detect that you need to authenticate with Api ninjas
  • It will show you an authentication link
  • Open the link in your browser (or copy/paste it)
  • Complete the Api ninjas authorization flow
  • Return to the terminal and start using Api ninjas through Claude Code

Once authenticated, you can ask Claude Code to perform Api ninjas operations in natural language. For example:

  • "Get real-time bitcoin price and market data"
  • "Check if this email is disposable"
  • "Look up bank info for this BIN"

Complete Code

Here's the complete code to get you started with Api ninjas and Claude Code:

import os
from composio import Composio
from dotenv import load_dotenv

load_dotenv()

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

composio_client = Composio(api_key=COMPOSIO_API_KEY)

composio_session = composio_client.create(
    user_id=USER_ID,
    toolkits=["api_ninjas"],
)

COMPOSIO_MCP_URL = composio_session.mcp.url

print(f"MCP URL: {COMPOSIO_MCP_URL}")
print(f"\nUse this command to add to Claude Code:")
print(f'claude mcp add --transport http api_ninjas-composio "{COMPOSIO_MCP_URL}" --headers "X-API-Key:{COMPOSIO_API_KEY}"')

Conclusion

You've successfully integrated Api ninjas with Claude Code using Composio's MCP server. Now you can interact with Api ninjas directly from your terminal using natural language commands.

Key features of this setup:

  • Terminal-native experience without switching contexts
  • Natural language commands for Api ninjas operations
  • Secure authentication through Composio's managed MCP
  • Tool Router for dynamic tool discovery and execution

Next steps:

  • Try asking Claude Code to perform various Api ninjas operations
  • Add more toolkits to your Tool Router session for multi-app workflows
  • Integrate this setup into your development workflow for increased productivity

You can extend this by adding more toolkits, implementing custom workflows, or building automation scripts that leverage Claude Code's capabilities.

FAQ

What are the differences in Tool Router MCP and Api ninjas MCP?

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

Can I use Tool Router MCP with Claude Code?

Yes, you can. Claude Code 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 Api ninjas tools.

Can I manage the permissions and scopes for Api ninjas while using Tool Router?

Yes, absolutely. You can configure which Api ninjas 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 Api ninjas data and credentials are handled as safely as possible.
