About this plugin
Some providers validate the client TLS fingerprint. A browser or the official CLI gets through without issue, but DSH carries a different fingerprint and is immediately flagged as an unauthorized client, producing a 403. dsh-fingerprint-relay exists to solve exactly this class of problem.
The plugin starts a lightweight local Python process that acts as an egress proxy. It makes the upstream connection with a fingerprint the allow-list accepts, then transparently forwards DSH traffic through it. The process binds to 127.0.0.1 only and stores no API keys; credentials remain in the provider configuration where they already live. The relay currently supports the Anthropic Messages channel and runs on Windows.
If you use DSH Desktop to reach agentrouter.org or any other fingerprint-gated provider and keep hitting unauthorized client detected or 403 responses, this plugin is a practical shortcut. With Python 3.11 or later on the machine, you only need to add one relay rule in Settings and point a provider at it.
Use Cases
- DSH receives a 403 or unauthorized client detected error when calling fingerprint-gated providers
- A provider allow-lists by TLS fingerprint so browser calls succeed but DSH requests are rejected
- Routing DSH Anthropic Messages traffic through a trusted local egress to pass fingerprint checks
Best For
- DSH Desktop users hitting 403 or unauthorized client errors on fingerprint-gated providers
- Windows developers who need a local proxy to forward DSH traffic
- Users who want to resolve TLS fingerprint mismatches without moving API keys
