Built for real-world AI security
Validate tool calls before your agent executes them
An AI agent tries to make an HTTP request to an internal metadata endpoint. Agent Sentry blocks the SSRF attempt and returns a denial with a signed receipt.
const result = await fetch('https://api.ragsentry.dev/v1/agent/tool/validate', {
method: 'POST',
headers: {
'Authorization': 'Bearer YOUR_API_KEY',
'Content-Type': 'application/json'
},
body: JSON.stringify({
tool_type: 'http',
tool_input: { url: agentRequest.url, method: 'GET' },
policy_id: 'prod-policy'
})
}).then(r => r.json());
if (result.decision === 'allow') {
await executeTool(agentRequest);
} else {
console.log('Blocked:', result.reasoning);
}Sanitize documents before they enter your vector database
A customer support bot retrieves knowledge base articles via RAG. An attacker submits an article with hidden instructions. RAG Sentry catches the injection before it's indexed.
const result = await fetch('https://rag-sentry.p.rapidapi.com/v1/sanitize', {
method: 'POST',
headers: {
'X-RapidAPI-Key': 'YOUR_API_KEY',
'Content-Type': 'application/json'
},
body: JSON.stringify({ content: document.text, content_type: 'text' })
}).then(r => r.json());
if (result.risk_score < 0.5) {
await vectorDB.upsert({ content: result.sanitized_content });
} else {
console.warn('Rejected:', result.recommendations);
}
