Hermes desktop OAuth refresh bug forces constant reauth with Tinyfish MCP

branalytc · x · 2026-09-09

A user reported to Teknium that Hermes v0.21.1 cannot retain Tinyfish MCP OAuth credentials: login succeeds, but the refresh request returns HTTP 400 and forces reauthentication. Upstream issue #62333 tracks the same refreshtoken bug. The user says this is the main reason they stopped using Hermes desktop and asks for a fix to be prioritized.
