SWEN.AI MCP Server (reference source)

This repository contains the reference implementation of the source code behind the public Model Context Protocol (MCP) server hosted at:

https://swen.ia.br/api/mcp

SWEN.AI is a Brazilian portal covering AI news, model benchmarks, tools and tutorials. This MCP server exposes that data to AI agents and MCP-compatible clients (Claude, Claude Code, etc.) with no API key required (IP-based rate limiting only).

This is not a runnable standalone package

The files here are copied verbatim from our private production monorepo so that developers can read, audit, and understand exactly what the hosted endpoint does. Authentication, rate-limiting, and infrastructure code are intentionally not included — see Security below.

To use the server, connect your MCP client directly to the hosted endpoint; there is nothing to install or run locally.

Available tools

Every tool is a thin wrapper: it validates input, calls a fetchers.ts function to read from Postgres (via Supabase's REST API using the public anon key), maps the row to a stable public contract (mappers.ts / types.ts), and returns JSON.

Files in this repo

src/lib/api-v1/
  mcp-server.ts     tool registration (the 7 tools above)
  fetchers.ts       data-fetching functions (reads only, public anon key)
  mappers.ts        DB row → public contract mapping
  types.ts          public contract types (NewsItem, ModelItem, ...)
src/lib/ranking/
  fetch-aa.ts       canonical Artificial Analysis ranking logic (dedup + sort)
src/lib/benchmark/
  freshness.ts      filters out stale benchmark scores
src/lib/i18n/
  config.ts         locale constants used by the mappers

These are copied byte-for-byte from the production repo. They are kept in sync manually; they may lag the deployed version slightly.

Security

This repo deliberately excludes:

• auth.ts — API key validation and rate-limiting logic

• key-crypto.ts — API key hashing

• Any environment variable, credential, or internal Supabase project reference beyond the two values that are public by design: NEXT_PUBLIC_SUPABASE_URL and NEXT_PUBLIC_SUPABASE_ANON_KEY (already shipped in every page's browser bundle on swen.ia.br; access is governed by Postgres Row Level Security, not by keeping this value secret).

If you believe you've found a security issue with the hosted endpoint, please report it privately rather than opening a public issue.
