Operate the optional OpenAI Secure MCP Tunnel or Linux Cloudflare Tunnel ingress; manage credentials, lifecycle and health evidence within each distinct trust boundary.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Operate optional ServerFS tunnel ingresses **Two separate transport adapters:** OpenAI Secure MCP Tunnel (existing) and Cloudflare Tunnel (Linux Compose, shipped in v0.24.0; live validated only on isolated read-only staging). Never mix their credentials, configuration or health evidence. The OpenAI Tunnel is an optional authenticated ChatGPT ingress adapter. Treat it as a separate subsystem with its own control-plane credentials, lifecycle and health evidence. ## When to use Use this skill when the user explicitly wants to: - connect ServerFS to ChatGPT through the OpenAI Secure MCP Tunnel; - expose Linux Streamable HTTP through an independently authenticated Cloudflare Tunnel; - configure Tunnel control-plane credentials or Tunnel-specific proxy routing; - bootstrap/update the official Tunnel client on native Windows/macOS; - restart/re-establish the Tunnel after a ServerFS deployment change; - diagnose Tunnel readiness, control-plane polling or response delivery. ## When NOT to use Do not use Tunnel as the default path for generic MCP clients; Linux supports direct Streamable HTTP. Do not use this skill for: - static ServerFS HTTP API Key or OAuth: `serverfs-auth`; …

How to install
mdr add ntlx/serverfs_mcp/serverfs-tunnel@sha256:f12f39e969296dd6The line at the top of this page pins the label git:20261106.be73c3e, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
