    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    MCP.AI for IDE agents (Cursor, etc.): log in in the browser, copy the access token. Best: add it to this server's config as a header `Authorization: Bearer <token>` for a permanent, non-expiring connection. Or paste it here for a session-only login: call with { token: "<jwt>" } after the user pastes, or with no args to get the link.

      What this check looks for
    Description, as the server wrote it
    The official mcp.ai marketplace — the in-platform catalog of every MCP/tool, AND the way to run them. Covers capability requests like "find an MCP that does X", "consulta um CPF", "is there a tool for Y". Core flow: action=search discovers MCPs by intent → describe returns one MCP's full profile (every tool with its id + params, pricing, auth) so you pick the right tool_id → invoke RUNS that tool. KEY: invoke works even when the MCP is NOT installed — it runs the tool pontualmente (one-off), without adding the MCP to the toolkit and without bloating the tool list. If the MCP needs a credential/login, invoke returns a connect link; if it is paid and the wallet is empty, invoke returns a checkout/top-up link (the user opens it, then you retry). Use install only to make an MCP PERMANENT in the active toolkit (its tools then show up natively in future sessions); prefer invoke for a single/occasional use. list_tools lists what is callable right now. subscribe/cancel handle per-MCP billing; report_bug sends feedback; request_mcp asks us to build a NEW MCP when nothing fits. Search/describe flag installed_in_toolkit vs installed_in_workspace. Writes (install/uninstall/subscribe/cancel and the one-off install behind invoke) require workspace owner/admin. It also carries the mcp.ai PROMPT LIBRARY, which is about ready-made prompt TEXT rather than MCPs: search_prompts finds one, get_prompt returns its full text with {{variables}} filled, and publish_prompt saves a prompt and returns a shareable mcp.ai/p/<slug> link that opens without login.

Retorna órgão, estado, município, modalidade, situação, datas e a referência (cnpj/ano/sequencial) pra detalhar. Aceita VÁRIOS termos em `termos[]`: cada um vira uma busca separada (disparadas com um intervalo entre si pra não pegar rate limit), e os resultados voltam fundidos e deduplicados numa lista só, com `termos_buscados`. IMPORTANTE: a busca full-text NÃO traz valor (vem sempre null) e não filtra por valor. Pra filtrar/ordenar por VALOR use pncp_listar (com apenas_abertas + termos + valor_min/valor_max) ou pncp_historico (faixa de valor sobre a base acumulada).

    Busca PRINCIPAL de licitações abertas por palavra-chave, faixa de VALOR, estado, modalidade e período. Cobertura agregada e instantânea de vários portais. Já vem com VALOR estimado por item e RANQUEADA por valor (maior 1º) automaticamente. Os `termos` são EXPANDIDOS em sinônimos automaticamente (ex.: 'software' busca também saas, licença de uso, sistema...). TUDO opcional: sem datas, usa os próximos 30 dias por abertura. Use termos[] pra palavra-chave, valor_min/valor_max pra faixa, uf/modalidade pra estreitar; apenas_abertas=true (default). Cada item traz `id` + `valor`; pra itens/preços e leitura do edital use pncp_processo/pncp_texto. Passe incluir_valor:false pra uma lista rápida sem valor, ou expandir:false pra não expandir os termos. Modalidades: 1 Leilão-Elet, 4 Concorrência-Elet, 6 Pregão-Elet, 8 Dispensa, 9 Inexigibilidade, 12 Credenciamento.

Cobertura agregada de vários portais. Devolve uma página com o `id` de cada oportunidade (use em pncp_processo pro detalhe completo), datas de abertura/encerramento e, quando `edital_legivel:true`, os campos `cnpj`/`ano`/`sequencial` pra LER o edital com pncp_texto/pncp_arquivos.

    Description, as the server wrote it
    Busca de ÓRGÃOS/entidades compradoras por nome, UF e/ou portal. Devolve portal, UF, uasg, nome e info de pagamento. Útil pra achar o órgão e usar o filtro em outras buscas. Aceita VÁRIOS nomes em `termos[]`: cada um vira uma busca separada (disparadas com intervalo entre si pra não pegar rate limit), resultados fundidos e deduplicados. ATENÇÃO: termo muito amplo (ex.: 'prefeitura', 'ministerio') estoura a fonte, prefira UF/portal ou um nome específico. Com antecipagov=true, consulta a base do programa AntecipaGov.

    Description, as the server wrote it
    Detalhe de oportunidade(s) por `id` (de pncp_listar/pncp_oportunidades). DOIS modos: (1) `id` único → detalhe COMPLETO (objeto, situação, órgão, modalidade, ITENS com preços, `valor` estimado, datas) + `cnpj`/`ano`/`sequencial` pra LER o edital (pncp_texto/pncp_arquivos). (2) `ids` em LOTE → detalha vários numa só chamada (com throttle interno) e devolve RANKING por VALOR (maior 1º) — é a forma certa de RANQUEAR POR VALOR, já que a listagem não traz valor. Passe os `id` da página do pncp_listar em `ids` pra montar o ranking sem N chamadas.

Retorna, por vencedor, o CNPJ, a razão social, o valor REAL homologado (já com o desconto da disputa, melhor que o estimado), a natureza jurídica (separa estatal de privada, ex.: 'Empresa Pública') e o porte (ME/EPP vs Demais). Agrega por fornecedor (vários itens do mesmo vencedor viram uma linha) e traz o total homologado. Itens sem resultado são ignorados. Use numero_item pra um item específico; omita pra todos.
