dsh-client-masquerade

In the DeepSeek Harness ecosystem, many users rely on custom model providers but often hit barriers due to client identity verification enforced by gateways. Proxies like agentrouter or claude-code-router rigorously inspect request headers or bodies, rejecting unrecognized clients with 401 UNAUTHENTICATED or 429/503 errors, which hampers productivity. The dsh-client-masquerade plugin addresses this by enabling custom models to masquerade as Claude Code or Codex clients. Through one-click injection of forged headers and precise request body fingerprints, it bypasses these restrictions effortlessly. Core features include preset modes for Claude Code and Codex, customizable body injection, and intelligent queue adaptation with retry logic to handle busy upstream channels. The plugin offers an intuitive settings page and the mask_client model tool, allowing users to toggle, test, and manage disguise states without manual config edits. It is ideal for developers integrating third-party APIs in DeepSeek Harness, power users needing stable access to restricted gateways, and tech enthusiasts seeking a seamless experience. Whether for daily development or exploring new capabilities, this plugin lets you focus on innovation rather than network-layer hurdles.
