Collaborative application security testing between humans and agents via CLI and MCP
Sectool is a collaborative workbench for application security testing, not a scanner. It combines your ability to handle UI and stateful APIs with an agent's strength in analyzing and mutating traffic through a proxy. Together, you can perform more thorough testing with less effort.
