Available components
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security63
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS enforcement could not be verified: the plaintext port answered with HTTP 406, which proves neither a plaintext path nor enforcement. View diagnostics → Unverified
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability58
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 3197 tokens (~168/item across 19 items; 19 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage67
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 0% of tool parameters carry a description.Fail
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 19 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 20 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
How do I install the PNCP MCP server?
PNCP is a hosted endpoint at https://api.mcp.ai/p_pncp, 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.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
authenticate ~99
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.

connect ~42
Returns connection status and URLs. When all providers are connected, returns authenticated:true and empty pending[]. When credentials are missing, returns connect_url for the toolkit and per-install URLs.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
marketplace ~532
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.

pncp_buscar ~248
Busca licitações por PALAVRA-CHAVE no objeto (cobertura NACIONAL ampla, índice full-text), em editais, atas ou contratos. 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.

(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.

What is the PNCP MCP server?
PNCP is an MCP server listed in the public MCP registry as io.github.mcp-dir/pncp-mcp. Search Brazilian government tenders and public procurement (PNCP): find notices and auctions by keyw. This page covers its hosted endpoint (https://api.mcp.ai/p_pncp).
Is the PNCP MCP server safe to use?
PNCP scores 75 out of 100 on VerifyMCP. 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 PNCP MCP server expose?
PNCP exposes 19 tools: pncp_buscar, pncp_listar, pncp_oportunidades, pncp_processo, pncp_detalhe, and 14 more. Their descriptions and schemas cost roughly 3,070 tokens of context every time the server is loaded.
Does the PNCP MCP server require authentication?
No. We connected to PNCP without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
Is the PNCP MCP server still maintained?
PNCP is still listed as active in the MCP registry. We last reached this channel on 4 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
