Request: Reset signing key for dev.agentsim namespace

[Fato07]

Summary

I own the domain agentsim.dev and the server dev.agentsim/mcp (v0.3.1) is published on the registry, but I no longer have access to the Ed25519 private key that was used to originally publish it. The key was generated in a previous session and wasn't persisted.

What I need

A way to reset or re-authorize the dev.agentsim namespace so I can publish updates using a new keypair. I can prove domain ownership via DNS TXT record or HTTP challenge — the _mcp-auth TXT record on agentsim.dev is already configured and under my control.

Current state

• Server: dev.agentsim/mcp (v0.3.1)
• Remote URL: https://mcp.agentsim.dev/mcp
• Domain: agentsim.dev (managed via Cloudflare, I have full DNS control)
• DNS proof: _mcp-auth.agentsim.dev TXT record is set and resolves correctly

Goal

Set up automated CI publishing via GitHub Actions so the registry entry updates on every release. The workflow is built and tested — just need the signing key to match the namespace.

Thanks!
