## Introduction

DeepSeek Harness (dsh) is an open-source agent runtime from DeepSeek AI, and every part of it is a plugin, so you can swap out the model adapter, the tool registry, or the agent loop. It runs on the Cordis framework and comes with a local Web UI, a headless CLI runner, and a Python SDK. You can point it at DeepSeek V4-Pro and V4-Flash, or at Anthropic, OpenAI, and other OpenAI-compatible providers. It is MIT licensed and still in developer preview.
This guide shows how to connect your Cloudflare browser rendering account to DeepSeek Harness, and you can do it with either the Composio Connect CLI or the Composio Connect MCP. The dsh-base bundle gives shell execution as a first-class tool, so the CLI is the easiest path for personal use. It is quick to set up and needs no server config, and the MCP path works well too, since the harness comes with a built-in MCP client.

## TL;DR

### What is Composio Connect?
Composio Connect lets anyone plug 1,000+ applications directly into their agent harness, including DeepSeek Harness, through a single hosted MCP endpoint. Each task runs as a session, a scoped runtime that ties together the user, the available toolkits, authentication, and execution state. It can:
- Discover and load tools on-demand. A small set of meta tools lets the agent search for the right tool at runtime, so you never load hundreds of tool definitions into context.
- Chain tools in a sandboxed remote workbench. Multi-step workflows run server-side, passing outputs between tools and working with files in the session's sandbox, so long chains finish without a lot of back-and-forth with the LLM.
- Manage authentication end-to-end. Managed OAuth, per-user connected accounts, and account isolation are all handled for you, so you never wire up auth yourself.

## Connect Cloudflare browser rendering to DeepSeek Harness

### Prerequisites: Install DeepSeek Harness
DeepSeek Harness needs Node.js (20 or 22) and pnpm. Build it from source. This is also what the MCP path in Option 2 requires, since the built-in MCP client resolves its dependencies from the checkout:

```bash
git clone https://github.com/deepseek-ai/deepseek-harness.git
cd deepseek-harness
pnpm install
pnpm run build
pnpm dsh web
```

## What is the Cloudflare browser rendering MCP server, and what's possible with it?

The Cloudflare browser rendering MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Cloudflare browser rendering account. It provides structured and secure access to headless browser automation and rendering on Cloudflare’s global infrastructure, so your agent can capture screenshots, extract data, generate snapshots, and automate browser tasks on your behalf.
- Automated webpage screenshot capture: Instantly instruct your agent to capture high-quality screenshots of any web page or HTML content with custom viewport and clipping options.
- Combined DOM and visual snapshot generation: Direct your agent to create a full webpage snapshot with both the rendered HTML and an image, perfect for archiving or analysis.
- Precise HTML element scraping: Ask your agent to extract specific text, HTML, attributes, or box metrics from rendered web pages using CSS selectors—ideal for detailed data collection or monitoring changes.
- Account management automation: Enable your agent to fetch and manage all accessible Cloudflare accounts, making it easy to orchestrate browser rendering tasks across different environments.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `CLOUDFLARE_BROWSER_RENDERING_CAPTURE_SCREENSHOT` | Capture Screenshot | Tool to capture a webpage screenshot. Use when you need a visual snapshot of a URL or HTML with optional viewport and clipping. Always validate screenshot content — the tool returns a successful result even when the captured page is a 404 or error page, with no error signal raised. |
| `CLOUDFLARE_BROWSER_RENDERING_LIST_ACCOUNTS` | List Accounts | List all Cloudflare accounts accessible to the authenticated API token. Returns account IDs, names, types, and settings. Use this to retrieve a valid account_id required by other browser-rendering actions like capture_screenshot, scrape_html_elements, and take_webpage_snapshot. |
| `CLOUDFLARE_BROWSER_RENDERING_SCRAPE_HTML_ELEMENTS` | Scrape HTML Elements | Tool to scrape HTML elements for text, HTML, attributes, and box metrics. Use when you need detailed data of matched selectors after rendering a page. |
| `CLOUDFLARE_BROWSER_RENDERING_TAKE_WEBPAGE_SNAPSHOT` | Take Webpage Snapshot | Capture both rendered HTML content and a screenshot of a webpage in a single request. Returns the full DOM content as a string and a Base64-encoded screenshot image. Useful when you need both visual representation and page content for analysis. |

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

The Cloudflare browser rendering MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like DeepSeek Harness, Claude, Cursor, etc. directly to your Cloudflare browser rendering account. It provides structured and secure access so your agent can act on your behalf using natural language commands.

## Conclusion

### Way Forward
With Cloudflare browser rendering connected, DeepSeek Harness can now act on your behalf whenever you ask it to.
From here, you can extend the harness further:
- Connect more apps: Calendar, Slack, Notion, Linear, and hundreds of others are available through the same Composio Connect setup, and each new integration adds to what your agent can do for you.
- Build workflows across tools: Once multiple apps are connected, DeepSeek Harness can chain actions together, so it can turn an email into a calendar invite, a Slack message into a Linear ticket, or a meeting note into a follow-up draft.
- Use the plugin system: Wrap common Cloudflare browser rendering flows as dsh plugins or prompt templates so recurring tasks become one-line commands, and bundle your most-used Cloudflare browser rendering tools into a named profile you can boot on demand.

## Frequently Asked Questions

### What are the differences in Tool Router MCP and Cloudflare browser rendering MCP?

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

### Can I use Tool Router MCP with DeepSeek Harness?

Yes, you can. DeepSeek Harness 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 Cloudflare browser rendering tools.

### Can I manage the permissions and scopes for Cloudflare browser rendering while using Tool Router?

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