About Superagent
Open-source safety layer for AI agents.
Superagent is built by Superagent Technologies, a Y Combinator W24 company started in 2024 by Ismail Pelaseyed and Alan Zabihi. The team is small, the codebase is on GitHub at superagent-ai/superagent under the MIT licence, and the open-source SDK is the entry point for everything else they sell. The pitch is that a system prompt and a model provider's content filter are not enough on their own to keep an AI agent from leaking data, calling the wrong tool or following a malicious instruction hidden in a document.
The SDK exposes four methods you call on inputs, outputs or intermediate steps. Guard classifies a payload for prompt injection, jailbreak attempts, malicious instructions and unsafe tool calls, with open-weight models in 0.6B, 1.7B and 4B parameter sizes that run on your own infrastructure at 50 to 100 ms latency, or against the hosted API with no key required for the default model. Redact strips PII, PHI and secrets from text before it reaches the model or leaves your perimeter. Scan reads repositories and files (PDFs, images, URLs) for repo poisoning and other AI-agent-targeted attacks. Test runs red-team scenarios against a deployed agent so a release that quietly weakened the guardrails fails the build instead of fails in production. There is a TypeScript and a Python SDK, a CLI for batch and CI runs, and an MCP Server compatible with Claude Code and Claude Desktop. The same team also ships VibeKit (sandboxed code-agent execution), ReAG (reasoning-augmented generation), Grok CLI, Brin, and PolyResearch as separate open-source projects.
