Developer integrates OAuth with DeepSeek Harness via MCP proxy

By PulseAugur Editorial · [1 sources] ·

A developer details how they integrated an internal MCP server requiring OAuth with DeepSeek Harness (DSH), overcoming several silent failures in the process. The core issue was the DSH plugin's lack of direct OAuth support, necessitating a workaround. The solution involved creating a stdio proxy using `mcp-remote` to handle the OAuth dance, including dynamic registration, PKCE flow, and token refresh, while presenting a standard stdio MCP interface to DSH. The developer encountered and resolved traps related to certificate verification, localhost resolution, and PATH limitations within the DSH environment. AI

    Connecting DSH to an internal MCP server that requires OAuth

    <p><strong>The MCP plugin that ships with DSH has no OAuth support, and the expensive part of this task was not code — it was three layers of silent failure in the plugin loader.</strong> I put a stdio proxy in front of an internal MCP server, ended up with 33 registered tools, a…
