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.
