# BLACKPROOF Local MCP

This local MCP server checks a ProofPack, compares review snapshots, and serves public preparation checklists. The agent cannot access answers, evidence references, or files.

## What it does

BLACKPROOF Local MCP can review a selected ProofPack before it is sent and summarize differences between two review snapshots. Agents can also request public checklists for cyber reviews, internal audits, and questionnaires. Answers, evidence references, and documents stay out of the agent's view.

The server runs on the user's device over stdio. BLACKPROOF does not receive the data, but local transport alone cannot prevent a host from relaying results to a remote model. Private use calls for an end-to-end local client and model; otherwise, running the server locally does not ensure that results remain local.
