"Bitcoin" matching MCP servers:

Let any MCP client issue and verify EU AI Act Article 50 transparency receipts for AI-generated content, anchored to Bitcoin.

MCP server for Tersign, the evidence layer for agent commerce, enabling agents to issue, verify, and manage signed receipts, compliance records, refunds, and disputes on a counter-signed hash-chained ledger.

Enables AI agents to perform AML and compliance risk scoring for crypto addresses and transactions on Ethereum, BSC, TRON, TON, and Bitcoin, returning 0–100 risk scores, bands, flags, and detailed signals.

Blockchain-anchored e-signatures. Create, send, negotiate, and verify legally binding agreements — every signature anchored to XRPL + Bitcoin with public verification. Agents can pay autonomously.

Enables MCP clients like Claude and Cursor to protect local files with SELLAT proofs of existence, track their Polygon and Bitcoin anchoring status, add a qualified eIDAS timestamp seal, and verify files against proof files or evidence packages. Files are hashed on the user's machine, so only the SHA-256 hash is sent to the service.
