Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

uis-mcp-server CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

O que é

Servidor MCP da UNESCO UIS (UIS Data API, api.uis.unesco.org): educação, ciência, cultura e comunicação, por país e ano. Cinco tools — uis_search_indicators, uis_list_geo_units, uis_get_data, mais search/fetch (contrato Deep Research da OpenAI, únicas sem o prefixo uis_) — e três resources (uis://…); nenhum prompt (prompts/list não é servido). Idioma do servidor: inglês; fuso: UTC (src/config.ts). Licença dos dados: CC BY-SA 4.0 — por isso a UIS vive num servidor separado do ILOSTAT (CC BY): os dois regimes nunca coabitam (src/uis/provenance.ts).

Dois canais, o MESMO servidor (buildServer, src/server.ts):

  • Hospedado — https://uis.sidneybissoli.com/mcp, Cloudflare Worker. O repositório INTEIRO é o Worker: wrangler.jsonc na raiz, main = src/index.ts; não há subprojeto worker/.
  • npm — uis-mcp-server, stdio (src/cli.ts → dist/cli.js, bin). Sem bindings da Cloudflare: release corrente em Map com TTL no lugar do KV, catálogo baixado dos endpoints oficiais na primeira busca no lugar do D1 (src/uis/catalog-memory.ts), sem uso, rate limit nem auth. Tools, validações, limites e proveniência são idênticos. O Dockerfile existe só para o Glama (roda o stdio).

Comandos

npm run typecheck && npm test   # suíte offline (vitest)
npm run dev                     # wrangler dev — http://localhost:8787/mcp
npm run build                   # runtime stdio → dist/cli.js (o que vai ao npm)
node scripts/dump-surface.mjs --stdio   # fumaça do build: initialize → tools/resources/prompts
npm run deploy                  # wrangler deploy (o CI faz isso; ver CI)
node scripts/smoke-mcp.mjs      # smoke contra PRODUÇÃO
npm run surface:lock            # regrava surface.lock.json + o bloco do server.json (ver Trava)
npm run manifest:lhm            # regenera lhm.plugin.json (ficha do LobeHub) da superfície real
npm run eval                    # eval com MODELO REAL — CUSTA DINHEIRO

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
