APEX PSI MCP Server

Cryptographic truth infrastructure for AI agents.

One config line gives any MCP-capable AI agent (Claude, Cursor, Qoder, Cline, Windsurf, and more) five provenance tools: seal, verify, anchor, cite, audit.

Tools

Tool	Description
seal	Stamp a cryptographic receipt on content (SHA-256 + Ed25519)
verify	Verify a receipt is authentic
anchor	Anchor a receipt to Bitcoin via OpenTimestamps
cite	Generate a citation for a receipt (APA, BibTeX, MLA)
audit	Audit a chain of receipts for integrity

Installation

Add to your MCP client config:

{
  "mcpServers": {
    "apex-psi": {
      "command": "npx",
      "args": ["-y", "apex-psi-mcp"]
    }
  }
}

Or install locally:

npm install apex-psi-mcp

Configuration

Environment variables (optional):

APEX_API_BASE — API endpoint (default: https://apex-infrastructure.com/api)
APEX_API_KEY — API key for authenticated access

Usage

Once installed, your AI agent can:

Seal content — "Seal this document with APEX PSI"
Verify receipts — "Verify this receipt is authentic"
Anchor to Bitcoin — "Anchor this receipt to the Bitcoin blockchain"
Generate citations — "Cite this receipt in APA format"
Audit chains — "Audit this chain of receipts"

Every receipt carries a verify link to https://apex-infrastructure.com/verify — sealed arithmetic, public provenance.
