Cryptair Mcp Server

Gives Claude and other MCP clients six tools for cryptographic attestation on Hedera Hashgraph. You can certify a document to get a timestamped on-chain receipt, initiate a two-party attestation where both sides prove they hold the same file, or verify whether something's been tampered with. The server handles agent registration automatically,no signup flow, credentials get persisted locally after first use. Useful when you need verifiable proof of agreement between AI agents or want immutable receipts for documents without uploading the actual files. Both parties' hashes hit Hedera mainnet, so verification is third-party and permanent. Works across Claude Desktop, Cursor, Cline, Windsurf, and anything else speaking MCP over stdio.
