What is proxmox-auth?

Rules for configuring Proxmox API-token authentication, including token identity fields, privilege separation, and access-control setup. Proxmox is software for managing virtual machines and containers.

Documenting or troubleshooting Proxmox token authentication, configuring privilege separation, setting token ACLs, and choosing safer dedicated tokens instead of root tokens.

They prevent common authentication errors, such as putting token parts in the wrong configuration fields or overlooking the token's separate permissions.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5	$0.00000	$0.00438
Opus 5	$0.00000	$0.00219
Sonnet 5	$0.00000	$0.00088
Haiku 4.5	$0.00000	$0.00044

Security

Grade A, and why

proxmox-auth scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Proxmox auth & Privilege Separation

When documenting, troubleshooting, or changing auth/access tools:

Token identity

Config splits Proxmox’s user@realm!tokenid into auth.user + auth.token_name + auth.token_value.
Never put user!token in auth.user.
token_value is the UUID secret, not the token id.

Privilege Separation

privsep	Behavior
Yes (default, best practice)	Token needs its own ACL on `user@realm!tokenid`. Effective perms = user ∩ token.
No	Token inherits all user permissions. Lab shortcut; larger blast radius if `config.json` leaks.

Empty API results / odd 401–403 with a “valid” token almost always mean privsep=Yes and no token ACL. Do not “fix” docs by recommending privsep=No as the default — document it as an explicit lab bypass and point to token ACL setup.

Docs to keep aligned

User-facing: SETUP.md §1, proxmox-config/README.md, README Configuration
Research: .cursor/research/decisions.md (D8), changelog-notes.md
Tool copy: CREATE_TOKEN_DESC / create_token privsep default true in server.py

Safety

Prefer dedicated mcp@pve over root@pam tokens.
Optional auth_write (D31) elevates mutations; keep privsep=Yes + ACL on both token identities.
config.json must stay gitignored.
create_token returns the secret once — never log it at INFO.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
