Superagent SDK

Make your AI apps safe.

Website · Docs · Discord · HuggingFace

An open-source SDK for AI agent safety. Block prompt injections, redact PII and secrets, scan repositories for threats, and run red team scenarios against your agent.

Detect and block prompt injections, malicious instructions, and unsafe tool calls at runtime.

TypeScript:

import { createClient } from "safety-agent";

const client = createClient();

const result = await client.guard({
  input: userMessage
});

if (result.classification === "block") {
  console.log("Blocked:", result.violation_types);
}

Python:

from safety_agent import create_client

client = create_client()

result = await client.guard(input=user_message)

if result.classification == "block":
    print("Blocked:", result.violation_types)

Remove PII, PHI, and secrets from text automatically.

TypeScript:

const result = await client.redact({
  input: "My email is john@example.com and SSN is 123-45-6789",
  model: "openai/gpt-4o-mini"
});

console.log(result.redacted);
// "My email is <EMAIL_REDACTED> and SSN is <SSN_REDACTED>"

Python:

result = await client.redact(
    input="My email is john@example.com and SSN is 123-45-6789",
    model="openai/gpt-4o-mini"
)

print(result.redacted)
# "My email is <EMAIL_REDACTED> and SSN is <SSN_REDACTED>"

Analyze repositories for AI agent-targeted attacks such as repo poisoning and malicious instructions.

TypeScript:

const result = await client.scan({
  repo: "https://github.com/user/repo"
});

console.log(result.result);  // Security report
console.log(`Cost: $${result.usage.cost.toFixed(4)}`);

Python:

result = await client.scan(repo="https://github.com/user/repo")

print(result.result)  # Security report
print(f"Cost: ${result.usage.cost:.4f}")

Run red team scenarios against your production agent. (Coming soon)

const result = await client.test({
  endpoint: "https://your-agent.com/chat",
  scenarios: ["prompt_injection", "data_exfiltration"]
});

console.log(result.findings);  // Vulnerabilities discovered
