Cryptair Mcp Server
Record tamper-evident attestations and on-chain receipts on Hedera mainnet when your agent must prove what it did to a counterparty.
Overview
Cryptair MCP Server is a MCP server for the Ship phase that provides tamper-evident attestations and Hedera mainnet on-chain receipts for AI agents.
What is this MCP server?
- Tamper-evident attestation tools designed for AI agent workflows
- On-chain receipts on Hedera Hashgraph mainnet
- npm package @cryptair/mcp-server v0.1.1 with stdio transport
- Optional CRYPTAIR_API_KEY or runtime register_agent with ~/.cryptair/credentials.json
- submit_attestation with optional CRYPTAIR_EMAIL for counterparty auto-provision
- Package @cryptair/mcp-server version 0.1.1
- Default API base https://www.cryptair.io (CRYPTAIR_BASE_URL override)
- On-chain network: Hedera Hashgraph mainnet
What problem does it solve?
Agent outputs are hard to prove to third parties without cryptographic receipts that survive disputes and retroactive edits.
Who is it for?
Builders shipping agent-to-human or B2B agent workflows that need verifiable attestations and blockchain-backed audit trails.
Skip if: Hobby projects with no counterparty trust requirements or teams unwilling to run npm stdio MCP plus Cryptair accounts.
What do I get? / Deliverables
After configuring Cryptair stdio MCP, your agent can register, submit attestations, and anchor tamper-evident receipts on Hedera mainnet via Cryptair’s API.
- Submitted attestations with tamper-evident Cryptair records
- On-chain receipts on Hedera Hashgraph mainnet
- Runtime agent registration path when no API key is pre-set

How it compares
On-chain attestation MCP, not a generic secrets scanner or local-only unit-test skill.
Common Questions / FAQ
Who is Cryptair MCP Server for?
It is for developers who deploy AI agents that must leave tamper-evident, Hedera-anchored proof of actions for partners, customers, or compliance reviewers.
When should I use Cryptair MCP Server?
Use it during ship when you need attestations and on-chain receipts before or as you expose agent workflows externally, not for casual local prototyping alone.
How do I add Cryptair MCP Server to my agent?
Add the npm stdio MCP @cryptair/mcp-server to your client config, set CRYPTAIR_API_KEY optionally, or allow register_agent to store keys at ~/.cryptair/credentials.json per package docs.
