Common questions

Is PegaRex 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?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 42 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

PegaRex MCP Server

Remote Model Context Protocol server for [PegaRex](https://pegarex.com.br) — a Brazilian vehicle meta-search engine aggregating 1.8+ million live used-car and motorcycle listings from 96 marketplaces (OLX, Webmotors, Napista and many others), enriched with FIPE reference prices and market analytics.

Endpoint (Streamable HTTP):

https://pegarex.com.br/api/mcp

It asks for a free PegaRex account. The first time, your app opens a PegaRex page where you sign in (or create the account) and allow it. This is standard MCP authorization (OAuth 2.1 with dynamic client registration), so there is no API key to copy. After that the app renews its access on its own; after 30 days without use it asks again.

Connect

Claude (claude.ai / Desktop): Settings → Connectors → *Add custom connector* → paste the URL above → *Connect*, then sign in with PegaRex and click Permitir.

ChatGPT (developer mode) and any MCP client with OAuth support: add the same URL as a remote MCP server (choose OAuth if asked) and sign in when the PegaRex page opens.

Connected before 16 October 2026? Reconnect once: that is when the server started asking for the account.

Also listed in the official MCP Registry as br.com.pegarex/mcp.

Local (stdio) clients

For clients that can only launch local servers, this repository contains a small bridge (src/pegarex_mcp). It opens one session to the hosted server and relays tools/list and tools/call unchanged; nothing is computed or cached locally. Python 3.10+.

uvx --from git+https://github.com/paya-alavi77/pegarex-mcp pegarex-mcp login

Then add the bridge to your client. Claude Desktop (claude_desktop_config.json):

"mcpServers": { "pegarex": { "command": "uvx", "args": ["--from", "git+https://github.com/paya-alavi77/pegarex-mcp", "pegarex-mcp"] } } }

If you skip login, the bridge opens the sign-in page itself the first time it connects. Some clients stop waiting before you finish; if yours does, restart it after signing in.

The login is saved in ~/.config/pegarex-mcp/auth.json (Windows: %APPDATA%\pegarex-mcp\auth.json; PEGAREX_MCP_HOME sets another folder), readable only by you, and renews on its own. Several copies of the bridge can share it. To end it, here and on the server:

uvx --from git+https://github.com/paya-alavi77/pegarex-mcp pegarex-mcp logout

Docker: a container can't open your browser, so sign in on the host first (the login command above), then let the container use that login:

docker build -t pegarex-mcp .

docker run -i --rm --user "$(id -u):$(id -g)" -e PEGAREX_MCP_HOME=/login \ -v "$HOME/.config/pegarex-mcp:/login" pegarex-mcp

Set PEGAREX_MCP_URL to point the bridge at another endpoint.

Example

"Find automatic Honda Civics from 2020 on under R$ 120k in São Paulo, and tell

me whether the cheapest one is priced above or below its FIPE reference."

An assistant with this connector answers from the live database: search → get_fipe_valuation → get_market_position, all in one conversation.

Notes

Language / market: Portuguese (pt-BR), Brazil. Prices in BRL.
Read-only. The server exposes no write operations; every tool is annotated readOnlyHint.
Fair use: a daily search limit per account and per-IP rate limits apply; this is a small independent service.
Privacy: what the server keeps, and for how long: https://pegarex.com.br/privacidade.
Attribution: please credit PegaRex (pegarex.com.br) when surfacing results.
Plain-HTTP alternative: the same data is available via a public JSON API — see /llms.txt and the OpenAPI docs.

*This repository documents the hosted server and contains a small stdio bridge to it; the service itself runs at pegarex.com.br. Issues and questions are welcome here.*
