How to integrate Context.dev MCP with Codex
Codex is one of the most popular coding harnesses out there. And MCP makes the experience even better. With Context.dev MCP integration, you can draft, triage, summarise emails, and much more, all without leaving the terminal or the app, whichever you prefer.
Api Key
Context.dev is a web data API platform for scraping, extraction, brand intelligence, monitoring, and structured web data. Use it to turn public web pages into clean, AI-ready data without building brittle scrapers.

Why use Composio?
Apart from a managed and hosted MCP server, you will get:
- CodeAct: A dedicated workbench that allows GPT to write its code to handle complex tool chaining. Reduces to-and-fro with LLMs for frequent tool calling.
- Large tool responses: Handle them to minimise context rot.
- Dynamic just-in-time access to 20,000 tools across 1000+ other Apps for cross-app workflows. It loads the tools you need, so GPTs aren't overwhelmed by tools you don't need.
How to install Context.dev MCP in Codex
Run the setup command
Run this command in your terminal to add the Composio MCP server to Codex.
It will initiate the authentication in a browser window, authorize Codex to access your Composio account.
(Optional) Authenticate with OAuth
To authenticate manually, run the login command to open a browser window and authorize Codex to access your Composio account.
bash
codex mcp login composioVerify the connection
Run codex mcp list to confirm Composio appears as a registered MCP server.
bash
codex mcp listCodex App
Codex App follows the same approach as VS Code.
- Click ⚙️ on the bottom left → MCP Servers → + Add servers → Streamable HTTP:
- Fill the header and Key fields with
{ "x-consumer-api-key" = "ck_*******" }. - The Key is the Composio API key, that you can find on dashboard.composio.dev
- Click on Authenticate and authorize Codex to your Composio account and you're all set.
- Restart and verify if it's there in
.codex/config.toml
bash
[mcp_servers.composio]
url = "https://connect.composio.dev/mcp"
http_headers = { "x-consumer-api-key" = "ck_*******" }What is the Context.dev MCP server, and what's possible with it?
The Context.dev MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Context.dev account. It provides structured and secure access to web content, brand intelligence, website design details, monitors, documents, and usage data, so your agent can scrape webpages, extract structured data, research brands, parse files, and review monitoring activity on your behalf.
- Web scraping and structured extraction: Have your agent turn a public webpage into Markdown or crawl relevant website pages to extract information that matches your chosen structure and instructions.
- Brand research and discovery: Let the agent search for companies by name or domain, then retrieve brand details such as logos, colors, industry, and descriptions.
- Website design analysis: Direct your agent to inspect a website's colors, typography, spacing, shadows, fonts, and common component styles.
- Document and file parsing: Instruct your agent to convert uploaded documents, images, source files, or data files into Markdown that an AI assistant can use.
- Monitoring and usage oversight: Have your agent review web monitors, asynchronous scraping batches, WebDB collections, credit consumption, storage, row counts, and monitor limits.
Conclusion
You've successfully integrated Context.dev with Codex using Composio's MCP server. Now you can interact with Context.dev directly from your terminal, VS Code, or the Codex App using natural language commands.
Key benefits of this setup:
- Seamless integration across CLI, VS Code, and standalone app
- Natural language commands for Context.dev operations
- Managed authentication through Composio
- Access to 20,000+ tools across 1000+ apps for cross-app workflows
- CodeAct workbench for complex tool chaining
Next steps:
- Try asking Codex to perform various Context.dev operations
- Explore cross-app workflows by connecting more toolkits
- Build automation scripts that leverage Codex's AI capabilities

FAQ
Frequently asked questions
With a standalone Context.dev MCP server, the agents and LLMs can only access a fixed set of Context.dev tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Context.dev and many other apps based on the task at hand, all through a single MCP endpoint.
Yes, you can. Codex 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 Context.dev tools.
Yes, absolutely. You can configure which Context.dev 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 Context.dev data and credentials are handled as safely as possible.

A lot of students tell us that the moment their connected tools start talking to each other inside Opennote feels almost magical. The agent just knows them, and it's immensely helped keep new users on the platform.

We chose Composio over Pipedream because it delivered depth where it mattered — niche tools and tricky edge cases other platforms simply ignored. That gave us confidence to scale without compromising.

As a solo builder, shipping fast is life or death. The only way I can outcompete incumbents is by outmanoeuvring them. Getting bogged down managing agent auth would have been a death sentence.

Before Composio, adding tool integrations was slow and resource-intensive. Each one could take weeks of engineering time, and maintaining them meant constantly keeping up with API changes.
