The anonymous tier is rate-limited to 30 requests/day per tool — fine for one-off queries, but it runs out fast in any automated workflow.
A free registered key gives you 100 req/day per tool at zero cost:
👉 kiprio.com/signup — no credit card, no trial period.
What you can do
Once connected, ask Claude naturally:
"Is noreply@company.io a real deliverable address?"
→ validate_email checks syntax, MX records, and disposable domain lists
"What tech stack is stripe.com running?"
→ tech_stack returns CMS, CDN, analytics, and payment providers
"Take a screenshot of this landing page and flag any broken layout."
→ screenshot_url returns a base64 PNG Claude can analyse directly
"Redact all PII from this support transcript before I send it to Zendesk."
→ redact_text replaces emails, phones, names, and card numbers with [REDACTED_TYPE]
"Check the SSL certificate on api.example.com — is it expiring soon?"
→ ssl_check returns expiry date, issuer, and grade
Building an automated agent?
kiprio tools are designed for pipelines and hooks, not just one-shot queries. Common patterns:
Email validation before accepting signups:
User submits email
→ Claude: validate_email("user@example.com")
→ If disposable/invalid → reject early, before DB write
Domain monitoring hook (Claude Code slash command):
/check-ssl → ssl_check on all domains in config/domains.txt
Lead enrichment agent:
CSV of company domains
→ Claude loops: tech_stack() + whois_lookup() + ip_lookup() per row
→ Output: enriched CSV with stack, registrar, country, hosting provider
Content moderation pipeline:
User-submitted text
→ sentiment_analysis() to flag negative
→ redact_text() to strip PII before logging
These patterns work within the free key tier (100 req/day per tool). Pro tier (1,000/day) handles larger batches.

Upgrade to Pro at kiprio.com →
Claude Code setup
pip install kiprio-mcp
claude mcp add kiprio -- kiprio-mcp
claude mcp list
With API key in your project .env:
echo "KIPRIO_API_KEY=your_key" >> .env
Then reference in your MCP config:
{
"mcpServers": {
"kiprio": {
"command": "kiprio-mcp",
"env": {"KIPRIO_API_KEY": "${KIPRIO_API_KEY}"}
}
}
}
