Use tool ↗About Superagent
Superagent sells a set of automated security workers for teams that let AI agents write and run code. They cover pull request review for code, contributor and supply-chain risk, checks on dependency updates before a PR opens, scheduled red-team reports, and guardrails that score content before an agent reads it or watch what an agent does at runtime. You connect repositories and agents through an API key, webhooks or the Superagent MCP server and get structured findings back, including into tools like Cursor and Claude Code. It started in 2023 as an open-source AI agent framework and has since moved to security; the maker is a Y Combinator W24 company.

Pros & cons of Superagent
A fit for engineering teams that already ship code written by agents and want an automated reviewer and guardrail layer rather than another dashboard. The free tier for open-source repositories is the easiest way to judge the findings. Private-repo pricing starts high, and the 500-credit cost of one red-team report means the entry plan buys only a single report per month.
Pros
- Free unlimited use on public repositories
- Covers PRs, dependency updates, red teaming and runtime guardrails in one product
- API and MCP access plus unlimited seats on every plan
- Founders maintain open-source guardrail and sandbox tooling
Cons
- Paid tiers jump from free straight to $499 a month
- Red-team reports consume 500 credits each, so the Starter plan covers one per month
- Product has pivoted from an agent framework, so older tutorials and docs may be out of date
Best for
- Open-source maintainers who want free automated PR security review
- Teams running coding agents that need guardrails on inputs and actions
Not for
- Small private teams on a tight budget, since paid plans start at $499 a month
- Buyers who need a traditional SAST or compliance scanner with long audit history
Watch out: A single red-team report costs 500 credits, which is the entire Starter plan's monthly allowance, so check how many reports you need before choosing a tier.
