msf-exploit-chain

msf-exploit-chain is a skill for Claude Code, Codex, Cursor from Suzu-Testing/metasploit-cursor-harness. It costs 69 tokens per session (3,144 once invoked), scanned A, original, MIT.

A guided workflow for using Metasploit, a security-testing toolkit, through connected coding-agent tools. It covers checking modules, running approved tests, handling sessions, and post-test actions under engagement rules.

In plain words
What is it for?
For authorized lab or security engagements that need reconnaissance, vulnerability checks, exploit tests, payload setup, session management, and post-exploitation work.
Why use it?
It keeps penetration-test steps organized and checks them against the allowed scope and rules of engagement. It also prevents unsafe defaults such as guessing the address used by reverse connections.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

msf-exploit-chain scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

MSF Exploit Chain

Harness context

  • MCP server: msf-harness (see .cursor/mcp.json)
  • ROE configs: engagements/{id}/roe.yaml
  • Scope: scope/scope-master.txt
  • Server-side enforcement: msf_harness/mcp/policy/roe.py
  • DoS modules (auxiliary/dos/*) are blocked unconditionally

Default engagement id for lab: lab-default

LHOST Resolution (mandatory before any reverse payload)

Resolve LHOST deterministically. Try in this order; use the FIRST that succeeds:

  1. msf_get_lab_network() -> use lhost field from response
  2. Read engagements/{engagement_id}/lhost.yaml -> use lhost value
  3. STOP and ask user for LHOST IP

NEVER hardcode an IP. NEVER use 0.0.0.0. NEVER guess.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
