Overview

What is Piqrypt Mcp Server?

Piqrypt MCP Server provides Model Context Protocol access to PiQrypt — the post-quantum cryptographic audit trail for AI agents. It is designed for developers and organizations needing tamper-evident, verifiable records of AI decisions in production workflows.

How to use Piqrypt Mcp Server?

Install via npx @piqrypt/mcp-server (recommended), npm install -g @piqrypt/mcp-server, or build from source. Configure the server in your MCP client (e.g., Claude Desktop or n8n) using the stdio transport, then invoke tools such as piqrypt_stamp_event, piqrypt_verify_chain, piqrypt_export_audit, and piqrypt_search_events.

Key features of Piqrypt Mcp Server

  • Post-quantum cryptographic audit trail for AI decisions.
  • Four core operations: stamp, verify, export, search.
  • Process isolation: crypto handled in a separate Python subprocess.
  • Compatible with any MCP-compliant client (Claude, n8n, Cursor, VS Code).
  • Local SQLite indexing for fast event search.
  • Compliant with AISS-1.1 and RFC 8785 canonical JSON.

Use cases of Piqrypt Mcp Server

  • AI agents signing every decision with cryptographic proof.
  • n8n workflows with built-in audit trail for automation.
  • Trading bots meeting SEC/FINRA audit requirements.
  • HR automation with GDPR-compliant AI hiring decisions.
  • Healthcare AI systems maintaining HIPAA audit trails.

Frequently asked questions

1

What is the security model?

All cryptographic operations (Ed25519, Dilithium3) happen in an isolated Python process. Private keys are never exposed to the MCP layer, and input validation is performed before subprocess calls.

2

What are the runtime dependencies?

You need Node.js 18+, Python 3.8+, and the PiQrypt core library (`pip install piqrypt`).

3

How do I install the server?

Run `npx @piqrypt/mcp-server` for a no-build install. Alternatively, install globally via `npm install -g @piqrypt/mcp-server` or build from source after cloning the repository.

4

Can I export audit trails for compliance?

Yes, `piqrypt_export_audit` exports events as JSON or pqz format, optionally with PiQrypt certification, suitable for SEC/FINRA or GDPR audits.

5

Where are events stored?

Events are stored locally in an SQLite index, used by `piqrypt_search_events` for fast querying. The exported audit trail is a portable proof verifiable without PiQrypt installed.
