Overview

AI-generated overview

MIZAN is a hosted MCP server that returns a signed ALLOW or REFUSE verdict before an agent pays, hires, trades or delegates, and lets it prove its own track…

What you can do
  • Check a counterparty or deal before money, work or authority changes hands, receiving one signed ALLOW or REFUSE answer.
  • Prove your own record — service reliability, forecast accuracy or trading returns — without revealing model, code, prompts or strategy.
  • Browse a use-case index mapping verbs to tools and results, the markets a requirement creates, and a ranked list of problems the service addresses.
  • Look up the published standard, its gates, the Bitcoin-anchored log and credential verification through the index tool.
When to use it
Use it when an assistant is about to pay, get paid, hire, buy, sell, lend, list, copy, delegate or allocate on behalf of a user, and you want a signed go/no-go check first. Also useful when an agent needs to demonstrate its own reliability or performance record to a counterparty.
Requirements
A remote MCP endpoint at studio.mizan.market, added over streamable HTTP; nothing to install locally. No authentication, environment variables or headers are declared in the manifest.
Before you install
The server sits directly in front of payment and trading decisions, so its ALLOW or REFUSE output should be treated as one input rather than final authority. The prove tool asks for records such as trading positions, which are submitted to a third-party hosted service; confirm what is retained before sending sensitive performance data.

Installation

In SourceWeft

  1. Open MIZAN · Proof before payment in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.muaviamohammed%2Fmizan/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

README

MIZAN MCP has moved

This repository is archived. The MCP server is hosted, so there is nothing to install:

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

The local stdio build and the registry manifest now live in the MIZAN monorepo:

check

THE ONE CALL BEFORE MONEY, WORK OR AUTHORITY CHANGES HANDS. Call before you pay, get paid, hire, buy, sell, lend, list, copy, delegate or allocate — on any agent, bot, company, wallet or strategy, on either side of the deal. Returns one signed ALLOW or REFUSE, free, in milliseconds: proceed only on ALLOW. On REFUSE the reply carries a proof request: forward it, and when the counterparty proves itself your next check returns ALLOW. Pass requirement="req_…@v" (or write one with require()) to check against someone's published bar: per-clause answers and the one step for each gap. agent = anything: a credential or agent id, a company domain, an API, MCP or A2A URL, github:<user>, hf:<org/repo>, npm:<package>, pypi:<project>, an SSH key or did:key, or a wallet on any chain. A linked identifier carries its owner's proof.

prove

PROVE WHAT YOUR OWN RECORD REALLY EARNED: how reliable your service is, how accurate your forecasts are, or what your trading really returned (call with no arguments for the guide to each). You never reveal your model, code, prompts or strategy; for a trading record only one position per bar (-1, 0 or +1) on a canonical market leaves your machine. mint=false (default): a free, private verdict with every gate and what would pass. mint=true with api_key: a zero-knowledge credential that every agent that checks you will see. Call with no arguments for the markets and the exact format.

Everything else MIZAN does: a use-case index (verb -> tool -> result) and the markets a requirement creates, grouped by job, plus the ranked list of problems MIZAN solves (more('problems')): verify a credential someone shows you, the published standard and its gates, the Bitcoin-anchored log and receipts, your identity and standing, checks beyond trading records (jobs, mandates, lending). Every tool listed is callable at this same address; the full list is also at https://studio.mizan.market/mcp/full.

100% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
