Mizan MCP

Mizan acts as an inspector for the x402 Bazaar, allowing agents to check payment endpoints before transacting. It provides tools to verify if an endpoint is safe, avoid scams, or proceed with payment by reconciling charges against on-chain evidence on Base. It offers verdicts like 'avoid', 'caution', or 'ok' based on its own purchases and measurements.

Endpoint and access

No sign-in to connect and list tools. Individual tools may still need a vendor account, credentials, or permissions; check the documented prerequisites.

What its tools do

3 tools, grouped by the hints the server advertises. Hints are self-declared, not verified behavior.

Not annotated (3)

3 of 3 have a description · 0 of 3 declare behavior hints · 2 of 2 with parameters document them all

Checks and signals

Each line is separate evidence, not a trust score.

  • Passed Endpoint answered the live check ·
  • Passed Official MCP Registry namespace is tied to mizan-bazar.higgsfield.app ·
  • Passed Endpoint is on the registry namespace domain ·
  • Availability 1 of 1 checks passed in 30 days

What you can do with it

  • Check an x402 endpoint before payment
  • Verify on-chain delivery of paid services
  • Get risk verdicts (avoid/caution/ok)

Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Call mizan_check with the endpoint URL before making any x402 payment. 'avoid' means Mizan paid that endpoint and got nothing back, with the charge visible on Base. 'unrated' means nobody has checked it — not that it is safe.

Tools

mizan_check — Check an x402 endpoint before paying it
Advertised by the server during the last successful anonymous check.

Free. Returns avoid / caution / ok / unrated for an x402 endpoint or operator, based on what Mizan measured when it bought from them with its own money. Call this before any x402 payment.

    "host": {
      "type": "string",
      "description": "Or just the hostname, to judge the whole operator."
    }
  }
}
mizan_report — What the paid report card contains
Advertised by the server during the last successful anonymous check.

Explains what evidence sits under a verdict for a given operator and how to buy it over x402. Does not itself cost anything.

mizan_coverage — What Mizan has measured so far
Advertised by the server during the last successful anonymous check.

Free. How many endpoints are on file, how many were actually bought, how many charge without delivering, and when the last survey ran.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http mizan-mcp-higgsfield https://mizan-bazar.higgsfield.app/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add mizan-mcp-higgsfield --url https://mizan-bazar.higgsfield.app/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable mizan-mcp-higgsfield in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "mizan-mcp-higgsfield": {
      "url": "https://mizan-bazar.higgsfield.app/mcp"
    }

}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).
Cline configuration

  "mcpServers": {
    "mizan-mcp-higgsfield": {
      "type": "streamableHttp",

      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start mizan-mcp-higgsfield and inspect its tools.
VS Code configuration
{
  "servers": {
    "mizan-mcp-higgsfield": {
      "type": "http",
      "url": "https://mizan-bazar.higgsfield.app/mcp"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.
Gemini CLI configuration
gemini mcp add --transport http mizan-mcp-higgsfield https://mizan-bazar.higgsfield.app/mcp

Claude Desktop

Open Claude Settings > Connectors > Add custom connector, enter this server URL and enable it for the conversation. This is a manual remote-connector handoff, not a desktop JSON configuration.

https://mizan-bazar.higgsfield.app/mcp

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.
Windsurf configuration
{
  "mcpServers": {
    "mizan-mcp-higgsfield": {
      "serverUrl": "https://mizan-bazar.higgsfield.app/mcp"
