Ask five questions before accepting an Al conclusion. What exactly is the claim? What evidence supports it? Is that evidence an artifact, a capability, or observed behavior? What failed, contradicted the claim, or remains unknown? What should a human verify before acting?

Go through improvement loops using your own and Al's assessment of the gaps. Review the output of Al's work, then give it your own feedback, based on your expertise, how it can improve the MCP server.

The MCP server summarizes tool output without dropping the findings. One "analyze_file" call to the MCP server runs 17 tools; their combined output can be more than fits in an Al model's context. The server extracts findings and indicators from the tools' output first, so a URL deep in the text still surfaces. The Al agent then gets a summary: key findings, every indicator, and paths to the full output on disk.The agent can decide to read the full output when it needs to, with trep or by fetching the file.

Three gaps for out of the box AI. AI knows the common tools, but the long tail of specialized ones takes practitioner expertise. AI states strong findings and weak guesses in the same confident voice. AI is non-deterministic, so two runs on the same sample can diverge.

Al ran this analysis end to end: unpacked and decoded the obfuscated batch script, rebuilt two hidden executables from fragments, decompiled Autolt scripts and wrote a decoder, recovered encrypted and compressed payload, matched it to the StealC malware family. 19 minutes, 39 tool calls, about $4 using Claude Opus 5.
