What it can do

Tool names and descriptions exactly as the server reported them on Nov 7, 2026. The maker wrote them, not us; we show them as plain text.

privi_token_market
PRIVI on Base: price, how much PRIVI and USDC the Privi swap desk holds (so whether a swap can fill), any Uniswap v3 / Aerodrome pools, and optionally a swap quote. Every paid Privi tool also accepts PRIVI. Free.
privi_pricing
List Privi Verify tools, what each costs, and how payment works.
privi_lookup_fingerprint
Check whether a record fingerprint (from a label, certificate or document) exists in Privi. Free.
privi_verify_lot
Verify a lot: product, first and latest custody events, recall status, and whether its record history is intact. Paid per call via x402.
privi_chain_of_custody
Full ordered event history for a lot with each event's fingerprint, plus an integrity check of the whole chain. Paid per call via x402.
privi_record_event
Append an event to a lot's history (manufacturers only). Requires 'Authorization: Bearer ' with a key from PRIVI_WRITE_KEYS. Over stdio, writes are allowed only when PRIVI_ALLOW_LOCAL_WRITES=1.

Common questions

Is Privi Verify safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.4.0) reached the registry 14 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

Privi Verify MCP

An MCP server that lets AI agents check where a manufactured lot came from and whether its records were changed after the fact, paid per call in USDC on Base using x402.

Works with any MCP client: Claude, ChatGPT, Cursor, VS Code, and custom agents.

Live (testnet): https://privi-verify.onrender.com/mcp · demo lots DEMO-STEEL-0001, DEMO-FOOD-0001

Built by Privi World Co (Port Huron, Michigan) as the agent-facing side of Privi ChainFlow.

Tools

Tool	Price	What it does
`privi_pricing`	free	Lists tools, prices, network, and the payout wallet
`privi_lookup_fingerprint`	free	Checks whether a record fingerprint (from a label, certificate or document) exists
`privi_verify_lot`	$0.01	Lot summary: product, first and latest custody events, recall status, record integrity
`privi_chain_of_custody`	$0.05	Full ordered event history with fingerprints and an integrity check
`privi_record_event`	API key	Manufacturers append events: `received`, `produced`, `inspected`, `shipped`, `transferred`, `recalled`

Prices are set with environment variables.

How records stay honest

Each event's fingerprint is a SHA-256 of its contents plus the previous event's fingerprint in the same lot. Editing or deleting any past event breaks every fingerprint after it, and both verify tools report exactly where the chain broke.

Each lot's latest fingerprint is anchored on the Privi blockchain every few minutes (see On-chain checkpoints), so anyone can check it without trusting Privi.

On-chain checkpoints

Every 5 minutes the server anchors the latest fingerprint of each lot that changed on the Privi blockchain through Privi Anchor. Audit results include onchain_checkpoint: the anchored position, transaction, and Merkle proof, plus an anchor_verify call anyone can run. If stored history no longer matches what was anchored, the audit fails even when every local hash was recomputed consistently. Set PRIVI_ANCHOR_KEY (an Anchor API key) to turn it on; PRIVI_ANCHOR_INTERVAL changes the period (seconds, default 300).

How payment works (x402 over MCP)

Follows the x402 v2 MCP transport spec:

The agent calls a paid tool. The server answers isError: true with a PaymentRequired object listing price, network, USDC contract and the payTo wallet.
The agent's wallet signs a USDC authorization and retries with it in _meta["x402/payment"].
The server checks the payment matches the price, has the facilitator verify it, runs the tool, has the facilitator settle it, and returns the result with the receipt in _meta["x402/payment-response"].

If settlement fails, the agent gets no result. Payments go straight to the PRIVI_PAY_TO wallet; the server never holds funds or private keys.

Run it

pip install .

cp .env.example .env # set PRIVI_PAY_TO and PRIVI_WRITE_KEYS python scripts/seed_demo.py # optional demo lots (or set PRIVI_SEED_DEMO=1) privi-verify-mcp # HTTP on :8000, MCP endpoint at /mcp

Over stdio (e.g. Claude Desktop):

"mcpServers": { "privi-verify": { "command": "privi-verify-mcp", "args": ["--stdio"], "env": { "PRIVI_PAY_TO": "0xYourWallet", "PRIVI_NETWORK": "base-sepolia" } } } }

Remote clients connect to https:// /mcp. GET /health returns status.

Make a test payment

scripts/test_payment.py pays the live server exactly the way an AI agent would, using a throwaway Base Sepolia wallet (free testnet USDC, no real money):

pip install eth-account

python scripts/test_payment.py --new-wallet # prints a test wallet address

get testnet USDC at https://faucet.circle.com (Base Sepolia), then:

python scripts/test_payment.py # pays $0.01, verifies DEMO-STEEL-0001, prints the tx link

The key is saved to .agent-wallet (git-ignored). The script refuses to pay on mainnet unless you pass --allow-mainnet.

Deploy

The Dockerfile runs on Railway, Render, Fly or any container host:

Set PRIVI_PAY_TO, PRIVI_WRITE_KEYS and PRIVI_NETWORK.
Mount a volume at /data so the SQLite database survives redeploys.
Start on `base-sepolia` with testnet USDC. Switch to base only after a full test payment works, and set PRIVI_FACILITATOR_URL to a production facilitator, since the public one is testnet only.

Recording events

curl https://<your-host>/mcp \

Develop

pip install -e ".[dev]"

pytest

Tests cover the payment flow (missing, mismatched, invalid and failed-settlement payments), tamper detection, and write authorization, using a stand-in facilitator.
