Introduction

Manage your Context7 directly from Claude Code with zero worries about OAuth hassles, API-breaking issues, or reliability and security concerns.

You can do this in two different ways:

Via Composio Connect - Direct and easiest approach
Via Composio SDK - Programmatic approach with more control

Why use Composio?

Only one MCP URL to connect multiple apps with Claude Code with zero auth hassles.
Programmatic tool calling allows LLMs to write its code in a remote workbench to handle complex tool chaining. Reduces to-and-fro with LLMs for frequent tool calling.
Handling Large tool responses out of LLM context to minimize context rot.
Dynamic just-in-time access to 20,000 tools across 1500+ other Apps for cross-app workflows. It loads the tools you need, so LLMs aren't overwhelmed by tools you don't need.

Connecting Context7 to Claude Code using Composio

1. Add the Composio MCP to Claude

Terminal

2. Start Claude Code

bash

claude

3. Open your MCP list

bash

/mcp

4. Select Composio and click on Authenticate

5. This will redirect you to the Composio OAuth page. Complete the flow by authorizing Composio and you're all set.

Ask Claude to connect to your account and authenticate via the link

What is the Context7 MCP server, and what's possible with it?

The Context7 MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Context7 account. It provides structured and secure access to programming library and framework documentation and code examples, so your agent can find matching libraries, resolve package names, retrieve current documentation, query technical guidance, and fetch relevant code examples on your behalf.

Library discovery: Have your agent search for libraries or frameworks that match a package or product name.
Package name resolution: Let the agent identify the right Context7 library before looking up its documentation.
Documentation retrieval: Direct your agent to fetch current documentation for a selected programming library or framework.
Focused technical questions: Instruct your agent to query library documentation for guidance on specific features, methods, or setup tasks.
Relevant code examples: Have your agent retrieve source-backed code examples that help explain how to use a library or framework.

Connecting Context7 MCP via Composio SDK

Composio SDK is the underlying technology that powers these integrations. It provides a universal gateway with full programmatic control. You can programmatically generate an MCP URL with the app you need (here Context7 MCP) for even more tool search precision. It's secure and reliable.

How the Composio SDK works

The Composio SDK follows a three-phase workflow:

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

Step-by-step Guide

Step by step10 STEPS

Prerequisites

Before starting, make sure you have:

Claude Pro, Max, or API billing enabled Anthropic account
Composio API Key
A Context7 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

npm install @composio/core dotenv

Install the Composio TypeScript library to create MCP sessions.

@composio/core provides the core Composio functionality
dotenv loads environment variables from your .env file

Generate Composio MCP URL

import 'dotenv/config';
import { Composio } from '@composio/core';

const { COMPOSIO_API_KEY, USER_ID } = process.env;

if (!COMPOSIO_API_KEY || !USER_ID) {
  throw new Error('COMPOSIO_API_KEY and USER_ID required in .env');
}

const composioClient = new Composio({ apiKey: COMPOSIO_API_KEY });

const composioSession = await composioClient.create(USER_ID, {
  toolkits: ['context7_mcp'],
});

const composioMcpUrl = composioSession?.mcp.url;

console.log(`MCP URL: ${composioMcpUrl}`);
console.log(`\nUse this command to add to Claude Code:`);
console.log(`claude mcp add --transport http context7_mcp-composio "${composioMcpUrl}" --headers "X-API-Key:${COMPOSIO_API_KEY}"`);

Create a script to generate a Composio MCP URL for Context7. This URL will be used to connect Claude Code to Context7.

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 Context7
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

node --loader ts-node/esm generate_mcp_url.ts
# or if using tsx
tsx generate_mcp_url.ts

Run your TypeScript 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 Context7 MCP to Claude Code

bash

claude mcp add --transport http context7_mcp-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 (context7_mcp-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 Context7 MCP server is properly configured.

This command lists all MCP servers registered with Claude Code
You should see your context7_mcp-composio entry in the list
This confirms that Claude Code can now access Context7 tools

If everything is wired up, you should see your context7_mcp-composio entry listed:

Claude Code MCP list showing the toolkit MCP server

Authenticate Context7

The first time you try to use Context7 tools, you'll be prompted to authenticate.

Claude Code will detect that you need to authenticate with Context7
It will show you an authentication link
Open the link in your browser (or copy/paste it)
Complete the Context7 authorization flow
Return to the terminal and start using Context7 through Claude Code

Once authenticated, you can ask Claude Code to perform Context7 operations in natural language. For example:

"Get documentation for requests.get in Python 3.11."
"Show code example for async file read in Node.js."
"Explain the difference between map and filter in JavaScript."

Complete Code

Here's the complete code to get you started with Context7 MCP and Claude Code:

import 'dotenv/config';
import { Composio } from '@composio/core';

const { COMPOSIO_API_KEY, USER_ID } = process.env;

if (!COMPOSIO_API_KEY || !USER_ID) {
  throw new Error('COMPOSIO_API_KEY and USER_ID required in .env');
}

const composioClient = new Composio({ apiKey: COMPOSIO_API_KEY });

const composioSession = await composioClient.create(USER_ID, {
  toolkits: ['context7_mcp'],
});

const composioMcpUrl = composioSession?.mcp.url;

console.log(`MCP URL: ${composioMcpUrl}`);
console.log(`\nUse this command to add to Claude Code:`);
console.log(`claude mcp add --transport http context7_mcp-composio "${composioMcpUrl}" --headers "X-API-Key:${COMPOSIO_API_KEY}"`);

FAQ

Frequently asked questions

With a standalone Context7 MCP server, the agents and LLMs can only access a fixed set of Context7 tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Context7 and many other apps based on the task at hand, all through a single MCP endpoint.

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 Context7 tools.

Yes, absolutely. You can configure which Context7 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.

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 Context7 data and credentials are handled as safely as possible.
