Tamper-evident attestation tools for AI agents — on-chain receipts on Hedera Hashgraph mainnet.

Cryptographic attestation for AI agents, exposed as native MCP tools. Lets any MCP-capable agent (Claude Desktop, Cursor, Cline, Windsurf, Zed, …) prove agreements, certify documents, and verify counterparty claims with on-chain receipts on Hedera Hashgraph. Works zero-config out of the box: agents can self-register and start using attestation immediately, with no email verification or…

Inferred from the transports this listing declares (stdio). A client not listed here hasn’t been ruled out — it just isn’t something Forge can confirm.

Verification confirms publisher identity (repo ownership), not code safety. The security scan covers known CVEs and suspicious install scripts.

Statically extracted from the published packagev0.1.1 · 3mo ago

Read out of the source npm actually ships, at scan time. The package was never executed. Tools registered dynamically at runtime, or hidden inside bundled or minified code, can be missed — so this is a floor on the tool surface, not a complete census of it.

Tool names and descriptions are written by the publisher and shown verbatim as inert text. They are the strings an MCP client passes to a model, so Forge scans them for prompt-injection patterns — any finding appears with the security scan above. “Privileged” is a keyword match on the tool name, not an audit of what the tool does: a benign-sounding name can still do anything.

About

Cryptographic attestation for AI agents, exposed as native MCP tools. Lets any MCP-capable agent (Claude Desktop, Cursor, Cline, Windsurf, Zed, …) prove agreements, certify documents, and verify counterparty claims with on-chain receipts on Hedera Hashgraph. Works zero-config out of the box: agents can self-register and start using attestation immediately, with no email verification or human-in-the-loop signup. Cryptair lets two agents (or an agent and a human) prove they agreed on the same…
