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 api key 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. ## Also integrate Cloudflare api key with - [ChatGPT Work](https://composio.dev/toolkits/cloudflare_api_key/framework/chatgpt) - [Antigravity](https://composio.dev/toolkits/cloudflare_api_key/framework/antigravity) - [OpenAI Agents SDK](https://composio.dev/toolkits/cloudflare_api_key/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/cloudflare_api_key/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/cloudflare_api_key/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/cloudflare_api_key/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/cloudflare_api_key/framework/codex) - [Kimi Code](https://composio.dev/toolkits/cloudflare_api_key/framework/kimi) - [Grok Build](https://composio.dev/toolkits/cloudflare_api_key/framework/grok-build) - [Cursor](https://composio.dev/toolkits/cloudflare_api_key/framework/cursor) - [VS Code](https://composio.dev/toolkits/cloudflare_api_key/framework/vscode) - [OpenCode](https://composio.dev/toolkits/cloudflare_api_key/framework/opencode) - [OpenClaw](https://composio.dev/toolkits/cloudflare_api_key/framework/openclaw) - [Hermes](https://composio.dev/toolkits/cloudflare_api_key/framework/hermes-agent) - [Pi](https://composio.dev/toolkits/cloudflare_api_key/framework/pi-agent) - [CLI](https://composio.dev/toolkits/cloudflare_api_key/framework/cli) - [Google ADK](https://composio.dev/toolkits/cloudflare_api_key/framework/google-adk) - [LangChain](https://composio.dev/toolkits/cloudflare_api_key/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/cloudflare_api_key/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/cloudflare_api_key/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/cloudflare_api_key/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/cloudflare_api_key/framework/crew-ai) - [Pydantic AI](https://composio.dev/toolkits/cloudflare_api_key/framework/pydantic-ai) - [AutoGen](https://composio.dev/toolkits/cloudflare_api_key/framework/autogen) ## 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 api key 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 api key MCP server, and what's possible with it? The Cloudflare api key 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 account. It provides structured and secure access to your Cloudflare services, so your agent can create DNS records, manage security rules, delete zones, and automate zone configurations on your behalf. - Automated DNS record management: Instantly create, update, or delete DNS records—including A, CNAME, TXT, and MX types—across your Cloudflare zones to keep your domains running smoothly. - Zone lockdown and security automation: Add or remove Zone Lockdown rules to restrict access to specific URLs and IP ranges, helping you enforce security policies without manual intervention. - Ruleset creation and maintenance: Direct your agent to create new rulesets or modify existing ones, ensuring your web applications remain secure and compliant with evolving access requirements. - Comprehensive zone administration: Effortlessly delete entire zones or DNSSEC configurations for streamlined domain management and cleanup when needed. - Versioned ruleset management: Retrieve specific versions of entry point rulesets, giving you granular control and auditability over your security configurations. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `CLOUDFLARE_API_KEY_CREATE_DNS_RECORD` | Create DNS Record | Tool to create a new DNS record in a Cloudflare zone.

With a standalone Cloudflare api key MCP server, the agents and LLMs can only access a fixed set of Cloudflare api key tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Cloudflare api key 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 api key tools. ### Can I manage the permissions and scopes for Cloudflare api key while using Tool Router? Yes, absolutely. You can configure which Cloudflare api key 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 api key data and credentials are handled as safely as possible. --- [See all toolkits](https://composio.dev/toolkits) · [Composio docs](https://docs.composio.dev/llms.txt)
