DeepSeek Harnesses the Cloudflare MCP Plugin

The `dsh-cloudflare-mcp` plugin for DeepSeek Harness (DSH) is designed to address the issue that DSH’s native client cannot complete Cloudflare OAuth 2.0 authentication. Built on the official SDK, it fills in the missing logic for dynamic client registration, PKCE validation, and loopback callbacks, and supports authorization through a web interface or Agent tools. Once authorized, the Agent can invoke Cloudflare’s full API suite (such as Workers, Pages, and D1) using the `mcp__cloudflare__*` prefix. The plugin supports automatic token refresh and can be installed via a local link. Note that tokens are stored locally only, and API routes listen on a loopback address.
