Verify MCP

@scopeblind/verify-mcp

MCP server for offline verification of ScopeBlind and Veritas Acta artifacts.

It is deliberately narrow:

• verify a single signed receipt or artifact
• verify an audit bundle offline
• explain a signed artifact in normalized form
• run a packaged self-test so clients can prove the verifier works

This is the registry-worthy MCP surface for the verification lane. It is not a gateway, not a builder, and not a hosted verification service.

Install

npm install -g @scopeblind/verify-mcp
