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 | $0.00045 | $0.00376 |
| Opus 5 | $0.00023 | $0.00188 |
| Sonnet 5 | $0.00009 | $0.00075 |
| Haiku 4.5 | $0.00005 | $0.00038 |
Grade A, and why
setup 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
Connect A1 Gallery
The plugin bundles one remote MCP server at https://www.a1.gallery/api/mcp. It needs a
free A1 account — anonymous calls return 401 account_required. There is no API key to
paste anywhere; sign-in happens over OAuth in the browser.
First connection
- Run
/mcpin Claude Code. - Pick a1 and choose Authenticate.
- A browser tab opens on a1.gallery. Sign in with a magic link or Google.
- The tab returns to Claude Code. Run
/mcpagain —a1should read connected.
Nothing else to configure. Tell the user to create the free account at https://www.a1.gallery/login if they do not have one.
When a tool returns 401 account_required
The session is signed out or the token expired. Re-run the steps above. This is the expected response for an unauthenticated call, not a fault in the server.
Quotas
| Tier | Per minute | Per day |
|---|---|---|
| Free account | 20 | 50 |
| A1 Pro | 60 | 2,000 |
A daily-limit response arrives as a tool result, not an HTTP error, so read its text and pass the message on. Pro is at https://www.a1.gallery/pricing.
Checking it works
Call get_design_filters. It takes no arguments and returns the taxonomy, so it confirms
both the connection and the account in one call.
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.

setup is a skill published in the GitHub repository bryntay/a1-mcp (1 stars, last pushed 6d ago), licensed MIT. It adds 45 tokens to every session and 376 once invoked, about $0.0002 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.
