Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "miniframe-tools": {
      "command": "npx",
      "args": [
        "-y",
        "miniframe-tools-mcp"
      ],
      "env": {
        "EVM_PRIVATE_KEY": "your-value",
        "MINIFRAME_API_URL": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add miniframe-tools --env EVM_PRIVATE_KEY=your-value --env MINIFRAME_API_URL=your-value -- npx -y miniframe-tools-mcp

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "miniframe-tools": {
      "command": "npx",
      "args": [
        "-y",
        "miniframe-tools-mcp"

        "MINIFRAME_API_URL": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "miniframe-tools": {
      "type": "stdio",
      "command": "npx",
      "args": [

        "MINIFRAME_API_URL": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Your choice stays on this device in a cookie; no account needed.

Values you fill in

EVM_PRIVATE_KEY secret required env
Private key of a wallet on Base funded with a small amount of USDC, used to sign per-call payments locally. Use a dedicated low-balance wallet; the key is never sent to the API.
MINIFRAME_API_URL env
Override the API base URL. Defaults to https://tools.miniframe.com.br

Common questions

Is Miniframe Tools safe?

It passed 1 of 1 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?

You need to fill in: EVM_PRIVATE_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.3.0) reached the registry 40 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

MiniFrame Tools

The Brazilian toolkit for AI agents — plus the web and document work agents can't do inside a sandbox.

Ask your agent to generate a Pix payment code, resolve a CEP to a full address, or pull a company's record from the CNPJ registry. Point it at a JavaScript-heavy page and get clean Markdown, a screenshot or a PDF back.

A CNPJ lookup costs $0.01 — billed per call, with no monthly plan, no contract and no minimum, which is unusual for Brazilian data APIs.

API: https://tools.miniframe.com.br
Try a tool in one click: storefront
Machine-readable spec: openapi.json · llms.txt

Tools

pix_brcode — Generate a Brazilian Pix payment code (BR Code / "Copia e Cola" string) plus a QR PNG. $0.01 per call.
cep_lookup — Resolve a Brazilian postal code (CEP) to a full street address. $0.005 per call.
cnpj_lookup — Look up a Brazilian company by its CNPJ number in the public registry. $0.01 per call.
empresa_profile — Consolidated Brazilian company profile to qualify a lead: registry + address completed via CEP + derived flags (active, headquarters, age, MEI/Simples, size, risk). $0.02 per call.
url_to_markdown — Fetch a JavaScript-rendered web page and return clean Markdown for an LLM. $0.02 per call.
screenshot_url — Take a screenshot of a web page and return it as PNG or JPEG. $0.03 per call.
url_to_pdf — Render a web page as a PDF. $0.03 per call.
extract — Extract the structured data a page exposes (JSON-LD, Open Graph, meta, tables, links) plus any fields you pass as CSS selectors. $0.02 per call.
compress_pdf — Compress a PDF file with Ghostscript. $0.02 per call.

Each tool maps to an HTTP endpoint of the same service:

Tool	Endpoint
`pix_brcode`	`POST /pix/brcode`
`cep_lookup`	`POST /cep`
`cnpj_lookup`	`POST /cnpj`
`empresa_profile`	`POST /empresa`
`url_to_markdown`	`POST /url-to-markdown`
`screenshot_url`	`POST /screenshot`
`url_to_pdf`	`POST /url-to-pdf`
`extract`	`POST /extract`
`compress_pdf`	`POST /compress-pdf`

What makes these worth paying for

Brazilian sources, handled properly. CEP lookups hit BrasilAPI first and fall back to ViaCEP automatically, so a single upstream outage doesn't break your agent. Both sources come back through one normalized, English-keyed shape — your prompt never has to know which one answered.

Pix codes built to spec, locally. The BR Code follows the Central Bank's EMV layout, CRC16 and all, generated on our side with no third-party payment provider in the path. The key you send is used to build the code and is not stored.

Privacy taken seriously. CNPJ responses carry the company record — legal name, trade name, status, main activity, address — with personal fields left out by design.

Rendering that doesn't become an attack surface. The web tools run real Chromium, so JavaScript pages resolve, and they refuse private and internal addresses (SSRF guard) before a page is ever loaded.

Nothing to install for the hard parts. Ghostscript and a headless browser are the kind of dependency an agent sandbox doesn't have and can't install. That is exactly what this is for — anything an agent already does well on its own (parsing a CSV, reading a spreadsheet) is not sold here.

Use it as an MCP server

Works with Claude Desktop, Claude Code, Cursor, Windsurf, Cline and any MCP client.

"mcpServers": { "miniframe-tools": { "command": "npx", "args": ["-y", "miniframe-tools-mcp"], "env": { "EVM_PRIVATE_KEY": "0xyour_private_key" } } } }

Restart the client and the seven tools appear. Then just ask:

"Generate a Pix code for R$ 50 to key abc@example.com, name Maria Silva, city Recife"

"What's the address for CEP 01310-100?"

"Look up CNPJ 00.000.000/0001-91 and tell me if the company is active"

"Turn https://example.com into Markdown so I can summarise it"

Use it as a plain HTTP API

No MCP needed — every tool is a normal endpoint:

curl -i -X POST https://tools.miniframe.com.br/cep \

-H "Content-Type: application/json" \ -d '{"cep":"01310100"}'

Paying

Calls are billed per request in USDC on Base, using the x402 protocol: the endpoint answers 402 with the price, your client signs the payment and repeats the request. Most agent runtimes handle this for you.

For MCP, set EVM_PRIVATE_KEY to a wallet funded with a few dollars of USDC — use a dedicated low-balance wallet, never your main one. The key stays on your machine and signs locally; it is never sent to the API.

Variable	Required	Default
`EVM_PRIVATE_KEY`	yes	—
`MINIFRAME_API_URL`	no	`https://tools.miniframe.com.br`

Over plain HTTP, wrap your client with any x402 library — see examples/ for a runnable Node script.
