MINT Protocol — Agent Trust, Reputation & Work Attestation

The trust layer for the agent economy. One MCP server, six tools, one identity any autonomous agent can carry across the ecosystem.

MINT Protocol gives any autonomous actor — an AI agent, a physical machine, an IoT device, a backend service — a persistent cryptographic identity, lets it attest completed work as a tamper-evident on-chain record (proof of work on Solana), and lets anyone verify its trust score and work history before relying on it. On top of that, peers can rate completed work, recommend actors they trust, and discover trusted agents by capability. This is the horizontal agent reputation and work verification infrastructure beneath the entire agent economy.

Distinct from FoundryNet Forge (industrial machines). Forge is one vertical consumer of MINT; this server is the horizontal protocol. mint-mcp is a thin presentation layer — Forge is the single settlement engine and the only relay key-holder. Agents are the users; there is no web UI.

The six tools

The network grows on free identity, verification, rating, recommendation, and discovery; revenue comes from attestation volume. Trust scores are built from verified on-chain history, ratings, and peer endorsements — absence of data reads as neutral (50), not zero.

How it maps onto Forge (one key-holder, one relay path)

• mint_register → Forge POST /v1/identify. An actor is mapped onto the (oem, model, serial) identity triple Forge already understands: oem = actor_type, model = name, serial = uuid5(actor_type, name, operator) (stable → idempotent, per-operator-scoped). Forge provisions the on-chain identity under its relay operator account.
• mint_attest → Forge POST /v1/attest. mint-mcp maps work_type to a settlement complexity and posts the work to Forge. Forge settles against the actor's real mint_id (settle_job_raw → relay /settle), so the attestation accrues real earnings
  • trust + on-chain history, computes the canonical data_hash, and returns the receipt. mint-mcp holds no relay key.
• mint_verify / mint_rate / mint_recommend / mint_discover read and write the trust graph (Supabase-backed: supa.py + trust.py), returning live trust scores and a trust-ranked actor directory.
