Nothing to run from here
5arz Proof Of Human is installed from its publisher's own source and answers where it runs, so this marketplace is not in the path of a single call. There is no address here to send one to, and a panel that pretended otherwise would be showing you an answer we made up. Install it and call it from your own client — the Installation tab has the entry for each one.

Installation
Where are you running it?
Every route below installs the same thing and ends at the same approval screen. Nothing here runs on your machine and nothing runs on ours: this server answers at its publisher’s own address, and what you install is the connection straight to it.
Claude Codedeclared by this listing
This is a public server: it answers at its publisher’s own address and this marketplace is not in the path. Claude Code registers it in one command; --scope user makes it available in every project. The transport below is http, as the publisher's own manifest declares it.
claude mcp add --scope user --transport http 5arz-proof-of-human-mcp https://mcp.5arz.comReconnect, or start a new session, and the tools appear in the model’s tool list.
Free on mcprush, and it answers at its publisher’s own address: this marketplace is not in the path, so there is no key of ours to hold and no card to add.
What it writes
One config entry pointing straight at the publisher’s own address — this marketplace is not in the path, and nothing from this listing executes on your machine.
What you approve
9 tools, with what each one reads, writes and reaches shown before you agree — the same list on every route above. Read the tool surface.

Create a 5arz API key so your agent can request proof-of-human credentials. Every new key starts on the Free plan — 1,000 credential seals a month and 10 document checks, no card. Pass mode:"test" for an unlimited free sandbox key (arz_test_…) whose credentials are marked test:true — never treat test credentials as production proof. The key is shown once; store it.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| name | string | yes | Your company or agent name. |
| contactEmail | string | yes | Contact email for the account. |
| mode | string | no | live for production keys; test for an unlimited free sandbox key. |
Mint a signed Proof-of-Human-Fulfillment (PoHF) credential attesting a real, ID-verified, live human performed an action. Provide sessionId to attest work fulfillment, or memberId to attest that an ID-verified human is behind an account (optionally wallet-bound). This does not establish that the person holds only one account — read sybil_checked in the returned claims before gating one-per-person
| Parameter | Type | Required | Notes |
|---|---|---|---|
| sessionId | string | no | Verified session to attest (work-fulfillment path). |
| memberId | string | no | Member to attest as an ID-verified, live human (personhood path). |

| walletSig | string | no | Optional EIP-191 personal_sign of the wallet challenge. |
| walletNonce | string | no | Optional wallet challenge nonce. |
| apiKey | string | no | Optional: pass your key here if your client cannot set the Authorization header. |
Independently verify a 5arz PoHF JWT: checks the ES256 signature against the live public JWKS and validates expiry/not-before, then returns valid/invalid plus the decoded claims. No API key needed — this is pure cryptographic verification you could also do with any standard JWT library. Accepts either the legacy pohf_jwt / pop_jwt or the standards-conformant sd_jwt_vc (IETF SD-JWT VC, typ dc+sd-jw
| Parameter | Type | Required | Notes |
|---|---|---|---|
| pohf_jwt | string | yes | The credential returned by verify_human — the compact JWT, or the sd_jwt_vc string (ends in ~). |
Return the current Verified-Human-Hour (VHH) index — the benchmark price of one hour of verified human work/attention, in USD. Free, no API key. Useful for pricing verified-human data and as a citable benchmark.

| Parameter | Type | Required | Notes |
|---|---|---|---|

Buy one slot of a verified human task. Called without payment it returns an HTTP 402 / x402 challenge with settlement instructions; settle USDC on the offered chain and call again with x_payment and purchase_id to receive an attestation_id — a verifiable Proof-of-Human-Fulfillment receipt. No API key required; the payment is the authentication.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| task_id | string | yes | Task id from list_verified_human_tasks. |
| x_payment | string | no | Optional X-PAYMENT settlement proof. Omit to receive the 402 challenge. |

No rule-by-rule report on file for this release
Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.
This listing is an address its publisher runs, and you connect to it directly — this marketplace is not in the path. The scanner reads packages and public source, and an address is neither. So there is no grade — not a withheld one, an unmeasured one.
Release history
This is an address its publisher runs: which release it serves is theirs to choose, so there is nothing here to pin. The history below is for reading; the current release on file is 1.0.0.

Any signed-in account that does not publish 5arz Proof Of Human can review it, once — before installing it or after. A review from an account that has installed it is marked as one.
No reviews yet
Nobody has reviewed this listing. The rating on the card is the mean of the reviews written here and nothing else, so there is no rating until somebody writes the first — which takes a signed-in account that does not publish it, and nothing else.
