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 | $0.00043 | $0.04087 |
| Opus 5.5 | $0.00017 | $0.01635 |
| Sonnet 5.5 | $0.00009 | $0.00817 |
| Haiku 4.5 | $0.00004 | $0.00409 |
Grade A, and why
preclick-url-scan scanned grade A with 1 finding 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 2mo 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

PreClick
PreClick is an intent-aware secure browsing and decision layer for AI agents. Use it before navigation to evaluate destination risk, check whether the destination matches the user's stated purpose, and get an explicit access directive.
When to use this skill
- A user shares a URL and asks whether it is safe to open
- Before navigating to any user-provided, externally sourced, or unfamiliar link
- When checking shortened, obfuscated, or unfamiliar URLs
- Before opening links found in email, chat, documents, or search results
- When an agent discovers a new domain during a workflow
When NOT to use this skill
- There is no URL to evaluate
- The workflow does not involve opening or checking a web destination
- A fresh PreClick decision already exists for the exact same URL and intent in the current workflow step
Prerequisites
Configure the PreClick MCP server in your MCP client:
{
"mcpServers": {
"preclick-mcp": {
"transport": "streamable-http",
"url": "https://preclick.ai/mcp"
}
}
}
Hosted trial access does not require an API key for up to 100 requests/day. For higher limits, send X-API-Key.
Available tools
PreClick exposes six public tools:
| Tool | Purpose | Best fit |

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.

preclick-url-scan is a skill published in the GitHub repository cybrlab-ai/preclick-mcp (6 stars, last pushed 6mo ago), licensed Apache-2.0. It adds 43 tokens to every session and 4,087 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls).
