Overview

AI-generated overview

PegaRex lets an assistant search 1.8M+ live Brazilian used-car and motorcycle listings and compare prices against FIPE reference values.

What you can do
  • Search live vehicle listings and look up a single listing by ID
  • Browse the taxonomy: brands, models, versions and filter options
  • Get market statistics and FIPE reference valuations
  • Analyze a listing's market position, price distribution, similar active listings and alternative models
  • Check cheapest states, mileage context, average days to sell and technical specs
When to use it
Useful when researching Brazilian used cars or motorcycles: finding listings by model, year, price or state, and judging whether a price is above or below its FIPE reference and the surrounding market.
Requirements
Remote Streamable HTTP endpoint with OAuth 2.1 sign-in to a free PegaRex account (no API key). Clients that only launch local servers need a Python 3.10+ stdio bridge via uvx, with a one-time browser login stored in a local auth file.
Before you install
Requires signing in to a PegaRex account and granting access; the bridge stores a renewable login token in a local auth file. Read-only, but a daily search limit per account and per-IP rate limits apply, and results should credit PegaRex. Data is pt-BR and prices are in BRL.

Installation

In SourceWeft

  1. Open PegaRex in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. 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/br.com.pegarex%2Fmcp/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

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

README

PegaRex MCP Server

[PegaRex MCP connector]

Remote Model Context Protocol server for PegaRex — 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.

Step-by-step guide (pt-BR): https://pegarex.com.br/mcp

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+.

Sign in once, from a terminal (this opens your browser), with uv:

bash
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):

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:

bash
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:

bash
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.
