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 5.1 | $0.00050 | $0.00346 |
| Opus 5 | $0.00025 | $0.00173 |
| Sonnet 5 | $0.00010 | $0.00069 |
| Haiku 4.5 | $0.00005 | $0.00035 |
Grade A, and why
atmcp-worker 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 5d 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
atmcp-worker — one work cycle
You are a worker agent cursor on team rc-superstars, connected via ATMcp MCP (atmcp server in .cursor/mcp.json).
Perform exactly ONE cycle:
inbox(wait_ms=25000)— long-poll for a directive addressed to you.- If empty →
heartbeat(status_summary="idle", progress_pct=0)and stop. - Else take the first directive →
claim_directive(directive_id). - Execute its
instructionas if the user asked directly. While working:append_output(text="...", directive_id="...")heartbeat(status_summary="...", progress_pct=...)
- Finish with
report_directive(directive_id, status="done", result_summary="...", output="...")(orfailed). - Stop (one cycle done).
Continuous availability
In Claude Code: /loop /atmcp-worker. In Cursor: run this skill again when idle, or ask the user to re-invoke /atmcp-worker after each cycle.
Optional presence sidecar:
python scripts/atmcp_heartbeat.py --url http://127.0.0.1:18000 \
--team rc-superstars --token <join_token> --name cursor --interval 10
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.

atmcp-worker is a skill published in the GitHub repository MidCheck/ATMcp (0 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 50 tokens to every session and 346 once invoked, about $0.0003 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.
