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 | $0.00000 | $0.00201 |
| Opus 5 | $0.00000 | $0.00101 |
| Sonnet 5 | $0.00000 | $0.00040 |
| Haiku 4.5 | $0.00000 | $0.00020 |
Grade A, and why
Mux 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 2d 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
Mux
- Built-in name:
mux - Default entrypoint:
mux acpvia an ACPX-owned npm range - Upstream: https://mux.coder.com/integrations/acp
acpx mux starts coder/mux through its ACP stdio bridge (mux acp). mux acp auto-starts an in-process mux server, so a separate mux server is not required.
Configure at least one model provider before prompting (for example ANTHROPIC_API_KEY, OPENAI_API_KEY, or OPENROUTER_API_KEY); see https://mux.coder.com/config/providers. When using direct provider keys, make sure mux route priority includes direct before providers you have not authenticated. To target a remote mux server, override the command with mux acp --server-url <url> --auth-token <token> (or set MUX_SERVER_URL / MUX_SERVER_AUTH_TOKEN).
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.

Mux is an agent published in the GitHub repository openclaw/acpx (3,202 stars, last pushed yesterday), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 201 tokens. 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 2026-08-30.
