Proof of existence for files from any MCP client: hashed locally, anchored on Polygon and Bitcoin.

Install

claude mcp add sellat-mcp -- npx -y [email protected]

Requires: SELLAT_API_TOKEN, SELLAT_DOWNLOAD_DIR, SELLAT_API_URL

Our take

Hashes files locally and anchors proofs of existence on Polygon and Bitcoin for later verification. It may suit users who need timestamped evidence without uploading file contents, but adoption is currently limited and the legal or evidentiary value of an on-chain proof depends on the surrounding process and jurisdiction.
