Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00028 | $0.00200 |
| Opus 5 | $0.00014 | $0.00100 |
| Sonnet 5 | $0.00006 | $0.00040 |
| Haiku 4.5 | $0.00003 | $0.00020 |
Grade A, and why
dirctl-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 yesterday.
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
dirctl Authentication
When the user asks to log in to the Directory, authenticate with dirctl, get a token, run dirctl auth login, or fix auth errors from the MCP tools, follow the dirctl-auth skill.
Binary lookup
Never run which dirctl or scan PATH. The binary must come from DIRECTORY_DIRCTL_PATH in the config or the bundled binary set by the npm wrapper. If neither is available, instruct the user to set DIRECTORY_DIRCTL_PATH in the config.
When to trigger
- "log in to the Directory"
- "authenticate with dirctl"
- "dirctl auth login"
- "get a token" / "refresh my token"
- MCP tools return auth or permission errors and the auth mode is
oidc
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.

dirctl-auth is a cursor rule published in the GitHub repository agntcy/dir-mcp (2 stars, last pushed 2d ago), licensed Apache-2.0. It adds 28 tokens to every session and 200 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
