How to integrate Builtwith MCP with Kimi Code

Kimi Code is Moonshot AI's open-source coding agent, powered by Kimi K2.6. It runs in your terminal, reads and edits code, executes shell commands, and plans multi-step tasks, with native MCP support for extending it to outside tools.

In this guide, I will explain the easiest and most secure way to connect your Builtwith account to Kimi Code via Composio Connect, so it can get all websites using Shopify in 2024, show historical tech changes for example.com, find online stores selling Nike shoes, and more without ever putting your account credentials at risk.

Why use Composio?

Composio provides:

  • Access to 1,000+ managed apps from a single MCP endpoint. This makes it convenient for agents to run cross-app workflows.
  • Managed OAuth. You do not have to worry about authentication and authorization flows for every app.
  • Programmatic tool calling. Allows LLMs to write code in a remote workbench to handle complex tool chaining. This reduces back-and-forth for frequent tool calls.
  • Large tool response handling outside the LLM context. This minimizes context bloat from large tool responses.
  • Dynamic just-in-time access to thousands of tools across hundreds of apps. Composio loads the tools your agent needs, so LLMs are not overwhelmed by tools they do not need.

Connect Builtwith to Kimi Code

Kimi Code is a TypeScript agent distributed through npm. It acts as an MCP client and reads server definitions from an mcp.json file, and it can also add and authenticate servers conversationally through /mcp-config. Composio is a remote HTTP server that authenticates with OAuth, so no API key is stored anywhere.

1. Install Kimi Code

The quickest way is the official install script, which requires no pre-installed Node.js and places the kimi executable on your PATH.

bash
# macOS or Linux
curl -fsSL https://code.kimi.com/kimi-code/install.sh | bash

# Windows PowerShell
irm https://code.kimi.com/kimi-code/install.ps1 | iex

# Confirm the installation
kimi --version

2. Log in

Start Kimi Code in your project directory, then sign in from the interactive UI:

bash
kimi

Run /login and choose Kimi Code OAuth using the device-code flow, or use a Moonshot API key.

3. Add Composio with /mcp-config

In current versions of Kimi Code, MCP servers are managed inside the app, not with a shell subcommand. From the interactive UI, run:

bash
/mcp-config
Kimi Code MCP config flow for adding the Composio MCP server

Tell it the server name and URL in plain language. For example:

Server name is Composio, and here is the server URL: https://connect.composio.dev/mcp

Kimi Code asks whether to add it globally, at ~/.kimi-code/mcp.json, or project-local for the current checkout, then writes the entry for you:

bash
{
  "mcpServers": {
    "Composio": {
      "url": "https://connect.composio.dev/mcp"
    }
  }
}

There is no transport field to set. Kimi Code infers HTTP from the url.

4. Restart the session

The new server is picked up on a fresh session, not the current one. Start a new session:

bash
/new

On the new session, Kimi Code detects that the server needs authorization and prompts you to run:

bash
/mcp-config login Composio

5. Authorize with OAuth

Run the command Kimi suggests:

bash
/mcp-config login composio

Kimi Code opens Composio's authorization page or surfaces a URL. Approve access, then return to the session. You should see confirmation that the Composio MCP server is connected.

Check the connection status any time with /mcp. Composio should appear as connected with its tools listed.

Connect your Builtwith account

Back in a Kimi Code session, ask the agent to connect to Builtwith or give it any Builtwith-related task.

For example, ask it to:

  • "Get all websites using Shopify in 2024"
  • "Show historical tech changes for example.com"
  • "Find online stores selling Nike shoes"

It will prompt you to authenticate and authorize access to Builtwith.

That is it. Composio tools are now available in Kimi Code, and your Builtwith account is ready to use.

Supported Tools & Triggers

Tools
Create Domain List FileTool to create a TXT or ZIP file from a list of domains.
Datasets LookupTool to access mass Internet technology usage information from 2000 to today.
Domain API LookupTool to retrieve current and historical technology information of a website.
Financial API LookupTool to fetch financial data for a domain.
Free API LookupTool to access last updated dates and counts for technology groups and categories for websites.
Lists API Get ListTool to retrieve a list of websites using a specific technology.
Product API LookupTool to find websites selling specific eCommerce products.
Recommendations API LookupTool to generate a list of websites with similar technology profiles.
Redirects API LookupTool to retrieve live and historical redirects for a website.

Conclusion

You have successfully connected Builtwith to Kimi Code using Composio Connect. Your agent can now manage Builtwith from the terminal with natural language, without exposing credentials in prompts or local scripts.

Since the same Composio endpoint exposes 1,000+ apps, you can add Slack, Calendar, Linear, and more to the same server and chain them into cross-app workflows.

FAQ

What are the differences in Tool Router MCP and Builtwith MCP?

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

Can I use Tool Router MCP with Kimi Code?

Yes, you can. Kimi 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 Builtwith tools.

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

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