About Orphograph
Orphograph is an MCP server published by the GitHub account Orphograph. Anchor a file's SHA-256 fingerprint to Bitcoin. The file never leaves the device.
It runs on your own machine: your AI client starts it from the MCP bundle package orphograph-mcp-0.1.2.mcpb at version 0.1.2.
It asks for one secret: ORPHO_API_KEY. Give it a key with the least access that still works.
Version 0.1.2 was published on 14 October 2026, and the source code is public, so you can read it before installing.
Written from the registry entry. 8 automated checks on the registry entry and the package code: 6 pass, 0 warn, 0 fail, 2 info. How we check.
