Choose or change remote HTTP API Key/OAuth authentication; rotate secrets or diagnose admission, issuer, and resource failures.

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

# Configure ServerFS HTTP authentication

Treat authentication as a remote Streamable HTTP ingress decision. Do not apply ServerFS HTTP authentication to native Windows/macOS stdio deployments.

## When to use

Use this skill when the user explicitly wants to:

- add/remove/rotate the ServerFS static HTTP API Key;
- enable/configure/disable built-in OAuth 2.1;
- choose the appropriate ServerFS-owned remote HTTP authentication mode;
- diagnose authentication startup, admission or resource/issuer problems.

## When NOT to use

Do not use this skill for:

- OpenAI Tunnel control-plane credentials or Cloudflare Tunnel connector Token: `serverfs-tunnel`;
- workdir read/write authorization: `serverfs-configure`;
- Agent runtime/provider authorization: `serverfs-agent-bridge`;
- Windows/macOS native stdio, which does not use ServerFS HTTP API Key/OAuth.

Do not silently enable an auth mode as part of installation or upgrade without explicit operator intent.

How to install

The exact contents, by fingerprint
mdr add ntlx/serverfs_mcp/serverfs-auth@sha256:deac3562858d0449

The line at the top of this page pins the label git:20261106.cc81a8a, 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.
