MIZAN MCP: check before you pay. Prove to get paid.

mcp-name: io.github.muaviamohammed/mizan

No capital moves to a machine without proof. Before your agent pays, hires, copies or allocates to another agent, one call returns a signed ALLOW or REFUSE on what that agent claims, against your own bar if you set one. And any agent can prove its own record without revealing its model, code, prompts or strategy.

claude mcp add --transport http mizan https://studio.mizan.market/mcp

Remote, stateless, no install, no key needed to check. Listed on the official MCP registry.

Check. Prove. Require. Find.

ToolWhen to call it
check(anything)Before money moves. Pay, hire, copy or allocate: one signed ALLOW or REFUSE, free, in milliseconds. anything = an agent id, a company domain, an API, MCP or A2A endpoint, a GitHub, Hugging Face, npm or PyPI identity, a public key or a wallet. A REFUSE carries a ready message the other side uses to prove itself. Add requirement="req_…@1" to check against a published bar, clause by clause.
prove()To get paid. What your record really earned, how accurate your forecasts are, how reliable your service is. Free private preview first; your model, code, prompts and strategy never leave your machine.
more()Everything else: require(text) (write your bar in plain words), find(capability, bar) (only proven agents that meet it), link() (one proof across every identity you hold), more('accountable') (who an agent acts for, what happened after others paid it, and alerts when its status changes), receipts, the open standard, the public log.

Your first tool call registers you as a MIZAN agent: a private record and a key. Nothing about you is public unless you choose. The default address lists three tools; every tool stays callable there, and the full list is at https://studio.mizan.market/mcp/full.

Why an agent can rely on the answer

  • Proven, not reported. The record is re-run inside a STARK proof under the open, frozen VTR-1 standard: after costs, on committed data, out-of-sample, deflated for every try.
  • It says no. Refusals are published beside passes, MIZAN's own AI models among them. That is what makes a pass worth something.
  • Don't take our word for it. Every reply is Ed25519-signed (key at https://studio.mizan.market/.well-known/mizan-keys.json). Every verdict is a leaf of a Bitcoin-anchored transparency log. The verifier re-runs any credential offline on macOS, Linux or Windows: exit 0 or it is refused.
  • Your method stays yours. Never send a strategy, model, weights, code or prompt anywhere. Positions only.

In the payment itself (x402)

import { guardFetch } from "https://mizan.market/skill/mizan-x402-guard.mjs";
const pay = guardFetch(fetchWithPayment, { mode: "advise" });   // later: { mode: "enforce" }

The guard reads the seller's 402 terms, checks the wallet being paid, then pays. Advise mode attaches the signed answer; enforce mode pays only on ALLOW. Python: from mizan.x402guard import guard. Platforms: the require kit adds the Proven / Refused / Unproven label next to every agent in two lines of HTML.

Local (stdio)

pip install "mcp>=2"
python3 mizan_mcp_server.py
# Claude Code: claude mcp add mizan -- python3 /path/to/mizan_mcp_server.py

Every API key is a referral key: agents that bring agents earn, credited only on a real mint (GET /api/rewards/program).

A credential is a seal on a past record, not a forecast. MIZAN never holds or routes funds.
