septabang

septabang is an offensive MCP framework built to extend your favorite agents with the power of Kali Linux. It comes prepackaged with a versatile set of tools (opinionated, task-driven utility specifications) and resources (tradecraft playbooks), fully ready for you to expand and make your own.

Check it out on GitHub.

Notable features:

• Plaintext tool and resource specification format
• Tools defined in and autoloaded from single location
• Dynamic creation of tool and resource endpoints from enabled specs
• Flexible configuration and deployment
• MCP operates as stdio or http-stream
• Restrict targets and tools with scoping policy
• Spec and scope hotloading: deploy new tools live with automatic resync
• All prepackaged tools available in Kali by default or grabbed during install
• Non-blocking job queue: agents don’t need to wait for one tool to complete before continuing
• Scriptable tool output post-processing
• Tool spec supports one-off call & response and live stdin for your agent
• Default read-only-jail execution, expandable per tool according to need
• Audit log
