Miniframe Tools MCP server

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.

Tools

• pixbrcode** — Generate a Brazilian Pix payment code (BR Code / "Copia e Cola" string) plus a QR PNG. $0.01 per call.
• ceplookup** — Resolve a Brazilian postal code (CEP) to a full street address. $0.005 per call.
• cnpjlookup** — Look up a Brazilian company by its CNPJ number in the public registry. $0.01 per call.
• empresaprofile** — 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.
• urltomarkdown — Fetch a JavaScript-rendered web page and return clean Markdown for an LLM. $0.02 per call.
• screenshoturl** — Take a screenshot of a web page and return it as PNG or JPEG. $0.03 per call.
• urltopdf — 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.
• compresspdf** — Compress a PDF file with Ghostscript. $0.02 per call.

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

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.

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