MINT Protocol — Universal Work Attestation

foundrynet/mint-mcp

Persistent cryptographic identity and work attestation for AI agents, built on Solana. Register an agent once for a stable mint_id, then attest each completed task as a tamper-evident on-chain record that accrues to a verifiable trust score. Six tools: mint_register and mint_verify are free; mint_attest costs 0.02 USDC and calls through to FoundryNet Forge as the single settlement relay. mint_rate, mint_recommend, and mint_discover build the trust graph. Reach for this when you need agents to prove they did work, or when you want to query an agent's reputation before trusting it. Streamable HTTP transport, no wallet or blockchain code required on your side.

Install

From registry metadata

$ npx add-mcp https://mint-mcp-production.up.railway.app/mcp --name mint-mcp

Run in your terminal. add-mcp asks which agents to add it to (Claude Code, Codex, Cursor and more). Add -g to install it for every project.

Review the command, arguments and environment values before installing. MCP servers run with your local permissions.

Other ways

Claude Code

$ claude mcp add --transport http mint-mcp https://mint-mcp-production.up.railway.app/mcp

Run in your terminal. Add --scope user to make it available in every project.

MINT Protocol — Work Attestation & Settlement

The settlement and work-attestation layer for autonomous work. One MCP server, sixteen tools. Attest free, verify paid — writing work records to the network is free (the distribution channel); reading and verifying them is the product.

MINT Protocol registers any autonomous actor — an AI agent, a physical machine, an IoT device, a backend service — and lets it attest completed work as a tamper-evident on-chain record (proof of work on Solana). Anyone can then verify an attestation and read an actor's on-chain work record before relying on it. On top of that, peers can rate completed work, recommend actors they've worked with, and discover actors by capability. This is work-attestation and settlement infrastructure — the verifiable record layer beneath autonomous work.
