# @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

```bash
npm install -g @scopeblind/verify-mcp
```

## Claude Desktop / MCP config

  "mcpServers": {
    "scopeblind-verify": {
