APEX PSI Overview

APEX PSI MCP server connects MCP-capable AI agents to APEX infrastructure for creating and checking cryptographic receipts. Its tools seal content with cryptographic signatures, verify receipt hashes against an append-only ledger, inspect or request Bitcoin anchoring, create citations, and validate receipt chains. Reach for it when an agent workflow needs provenance records or independent integrity checks rather than a judgment about whether content is true. The server runs through an MCP client configuration and can use an optional API endpoint and key.

Primary Use Cases for APEX PSI:
  • Seal documents with cryptographic receipts
  • Verify receipt hashes against the ledger
  • Check Bitcoin anchoring status
  • Generate APA, BibTeX, or MLA citations
