Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog) Scored 2026-09-28. - **Endpoint Security**: 74/100 - The endpoint's TLS certificate is valid, in date, and uses a strong key. - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. - HTTPS is enforced; there's no plaintext access path. - HSTS check failed: the Strict-Transport-Security header is absent. - DNSSEC check failed: this domain isn't protected by DNSSEC. - **Transport & Reachability**: 100/100 - Verified streamable-http transport via a live MCP handshake. - **Schema Quality & AI Usability**: 73/100 - AI-judged instruction clarity (good). - Context-footprint check failed: tool/resource definitions use about 1834 tokens (~107/item across 17 items; 17 tools + 0 resources), over budget; trim descriptions and params. - Usage-examples check failed: none of the tools include examples. - **Stability & Change Management**: 10/100 - Stability observed for 3 of 30 days with no destabilising changes; credit accrues until the full window elapses. - **Tool Coverage**: 67/100 - 100% of tools have a non-trivial description (not blank, and not just the tool's name). - 0% of tool parameters carry a description. - **Tool Safety**: 100/100 - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured. - We read all 17 captured tool definition(s), and no name or description among them implies an irreversible operation. - An AI judge read all 18 captured unit(s) of tool text and found none that tries to manipulate the model reading it. - **Capabilities**: 100/100 - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28. ## Install ### How do I install the PegaRex MCP server? PegaRex is a hosted endpoint at https://pegarex.com.br/api/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation. ### Claude ```bash claude mcp add --transport http br-com-pegarex-mcp 'https://pegarex.com.br/api/mcp' ``` ### Cursor ```json { "mcpServers": { "br-com-pegarex-mcp": { "url": "https://pegarex.com.br/api/mcp" } } } ``` ### VS Code ```json { "servers": { "br-com-pegarex-mcp": { "type": "http", "url": "https://pegarex.com.br/api/mcp" } } } ``` ### Codex ```toml [mcp_servers.br-com-pegarex-mcp] url = "https://pegarex.com.br/api/mcp" ``` ### opencode ```json { "$schema": "https://opencode.ai/config.json", "mcp": { "br-com-pegarex-mcp": { "type": "remote", "url": "https://pegarex.com.br/api/mcp", "enabled": true } } } ``` ### OpenClaw ```bash openclaw mcp add br-com-pegarex-mcp --url 'https://pegarex.com.br/api/mcp' --transport streamable-http ``` ### Hermes ```yaml mcp_servers: br-com-pegarex-mcp: url: "https://pegarex.com.br/api/mcp" ``` ### Netclaw ```json { "McpServers": { "br-com-pegarex-mcp": { "Transport": "http", "Url": "https://pegarex.com.br/api/mcp" } } } ``` ### Vellum ```bash assistant mcp add br-com-pegarex-mcp -t streamable-http -u 'https://pegarex.com.br/api/mcp' ``` ### Other ```json { "mcpServers": { "br-com-pegarex-mcp": { "type": "http", "url": "https://pegarex.com.br/api/mcp" } } } ``` The mcpServers block is a cross-client convention.

Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims. ### 2026-09-28 (score 70, +1) - [functional] We updated how we score, so this day's move reflects our rubric, not a change to the server ### 2026-09-26 (score 69, +1) - [security] The server rewrote its instructions, which are the text every model session reads - [security] Tool “search_vehicles” rewrote its description, which is the text the model reads - [functional regression] Schema quality: pass → fail - [functional improvement] Stability: unverified → 0.03 ### 2026-09-25 (score 68) First indexed and scored. ## MCP tools (17) ### `search_vehicles` (~424 tokens) Search vehicle listings Search 1.8M+ Brazilian vehicle listings aggregated from 96 platforms (OLX, Webmotors, Napista, etc.). Returns listings with price, year, mileage, location, source platform, the original ad URL, FIPE reference price and a deal_score (% vs FIPE; negative means priced below FIPE). Tips for best results: - Free-text `query` matches the listing TITLE only (e.g. "Onix LTZ turbo"). - For exact brand/model/version filtering, resolve names to ids first with list_brands / list_models / list_versions and pass brand_id/model_id/ version_id — it is faster and more accurate than the text fields. - `location` is a 2-letter UF (e.g. "SP") or a city name. - `sort_by="newest"` (default) lists the most recently LISTED cars first — the date a listing first appeared on its source, not when we last saw it. - `sort_by="best_deal"` ranks by lowest price-to-FIPE ratio. - `per_page` is capped at 50. Use `page` (1-20) to paginate; past the first 20 pages, narrow the search with filters. `total_count` and `total_pages` are returned. Input parameters: - `body_style` - `brand` - `brand_id` - `category` (string) - `fuel_type` - `location` - `mileage_max` - `mileage_min` - `model` - `model_id` - `page` (integer) - `per_page` (integer) - `price_max` - `price_min` - `query` - `sort_by` (string) - `source` - `transmission` - `version` - `version_id` - `year_max` - `year_min` ### `get_vehicle_by_id` (~71 tokens) Get listing by id Fetch the full details of a single listing by its PegaRex id: brand, model, version, year, price, mileage, fuel, transmission, city/state, FIPE price, deal_score, source platform and the original ad URL. Input parameters: - `car_id` (integer, required) ### `get_market_stats` (~53 tokens) Market stats Live size of the PegaRex database: total active listings, number of source platforms, and when the data was last refreshed. Use this for the current count instead of quoting a fixed number. ### `list_brands` (~64 tokens) List brands List available vehicle brands (makes) with their catalog id and active listing count. Pass a brand's id as `brand_id` to search_vehicles/list_models for fast, exact filtering. Input parameters: - `body_style` - `category` (string) ### `list_models` (~57 tokens) List models List models for a brand (pass brand_id from list_brands, or a brand name) with each model's catalog id and active listing count. Input parameters: - `brand` - `brand_id` - `category` (string) ### `list_versions` (~77 tokens) List versions List versions/trims for a model (pass model_id from list_models, or brand+model names) with each version's catalog id and active listing count. Input parameters: - `brand` - `category` (string) - `model` - `model_id` - `year_max` - `year_min` ### `list_filter_options` (~54 tokens) List filter options Return the valid values for the constrained search filters — fuel_type, transmission, sort_by — and the list of source platforms. Use this to build a valid call to search_vehicles in a single round-trip. ### `get_listing_details` (~49 tokens) Listing details Fatos do próprio anúncio (cor, portas, opcionais, vendedor, fonte, km, link).

That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm. ### What tools does the PegaRex MCP server expose? PegaRex exposes 17 tools: search_vehicles, get_vehicle_by_id, get_market_stats, list_brands, list_models, and 12 more. Their descriptions and schemas cost roughly 1,538 tokens of context every time the server is loaded. ### Does the PegaRex MCP server require authentication? No. We connected to PegaRex without credentials and it answered, so anything it exposes is reachable by anyone who knows the address. ### Is the PegaRex MCP server still maintained? PegaRex is still listed as active in the MCP registry. We last reached this channel on 28 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced. ## Links - Remote endpoint: https://pegarex.com.br/api/mcp - Repository: https://github.com/paya-alavi77/pegarex-mcp - Website: https://pegarex.com.br/mcp - Changelog RSS feed: https://verifymcp.io/servers/br-com-pegarex-mcp/api-mcp.xml - Changelog JSON feed: https://verifymcp.io/servers/br-com-pegarex-mcp/api-mcp.json - HTML version of this page: https://verifymcp.io/servers/br-com-pegarex-mcp/api-mcp
