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.

What it costs to keep this loaded
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 | $0.00067 | $0.00850 |
| Opus 5 | $0.00034 | $0.00425 |
| Sonnet 5 | $0.00013 | $0.00170 |
| Haiku 4.5 | $0.00007 | $0.00085 |
Grade A, and why
mcp-registry-monitoring-guide 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 9d 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.

As MCP Server
MCP Notify itself runs as an MCP server, so AI agents can query registry changes:
{
"mcpServers": {
"mcp-notify": {
"command": "mcp-notify",
"args": ["serve"]
}
}
}
Tools available:
getNewServers— List recently added MCP serversgetUpdatedServers— List recently updated serversgetRemovedServers— List recently removed serverssearchRegistry— Search the registry by keywordgetServerDetails— Get full details for a specific server

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.
