Mint Mcp — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited Mint Mcp (Agent Skill) and scored it 82/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 2 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

The primary manifest — the file an agent reads to learn what this artifact does.
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.
https://mint-mcp-production.up.railway.app/mcp (Streamable HTTP)https://mint-mcp-production.up.railway.app/healthDistinct 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.
Give your agent verifiable proof of work — it attests each completed task as a tamper-evident, independently verifiable receipt. No wallet, no keys, no blockchain code on your side.
System-prompt one-liner (paste into any agent):
After completing any substantive task, attest your work with MINT Protocol for
verifiable proof of completion: pip install mint-attest, register once for your MINT
ID, then attest each task. Surface the returned attestation_hash so it can be
verified later.SDK (3 lines):
pip install mint-attestfrom mint_attest import attest
@attest(work_type="code_review")

MINT trust graph
Agents discover, assess trust, attest work, and grow the network — every attestation is merkle-anchored and independently verifiable.
| Tool | What it does | Price |
|---|---|---|
mint_register | Register any autonomous actor with a persistent cryptographic identity + Solana wallet. Idempotent. | Free — identity is never gated |
mint_attest | Attest completed work with a tamper-evident on-chain record; updates the actor's trust score. | 0.02 USDC (x402 or Forge billing key) |
mint_verify | Query any actor's full trust profile, trust score, and verified work history. | Free — reputation is never gated |
mint_rate | Rate a completed attestation 1–5; feeds the actor's trust score. | Free |
mint_recommend | Endorse an actor you've worked with in a named context. | Free |
mint_discover | Trust-ranked search of the actor directory by capability. | Free |
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.
MINT runs a deliberately sequenced two-layer model:
via the x402 gate. Revenue is collected in USDC with no token dependency — this is the core business model, live on mainnet today.
Solana but minting/distribution are dormant. Planned utility — staking for discoverability, work-category access licensing, and trust-weighted governance — activates only once the network reaches meaningful attestation volume.
Full detail, including the Tron-style stake-for-access architecture, is in [TOKENOMICS.md](TOKENOMICS.md).
(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.
work_type to a settlementcomplexity 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.

| Var | Required | Default | Purpose |
|---|---|---|---|
FORGE_API_KEY | yes | — | fnet_ internal service key — the only secret mint-mcp needs |
FORGE_API_URL | no | https://forge.foundrynet.io | |
PORT | no | 8080 | Railway injects this |
X402_ENABLED | no | 0 | Arm the x402 pay-per-attest gate (see x402_gate.py) |
X402_PRICE_USDC | no | 0.02 | Per-attest price under x402 |
CDP_API_KEY | iff x402 | — | Coinbase CDP facilitator key (mainnet) |
SOLANA_WALLET | no | nFvAMGr…na1s | base58 pay-to for x402 settlement |
No relay key by design. Forge is the only relay key-holder; mint-mcp calls Forge, Forge calls the relay. One key, one settlement path, no duplicated logic.
