Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

jurisprudencia
jurisprudencia_buscar
Busca jurisprudência (acórdãos, súmulas, orientações jurisprudenciais, temas) por termo ou tese. Devolve, por registro: identificação da decisão, órgão julgador, relator, data, o trecho que casou a busca e o link para o documento no site oficial. Quando o registro traz `texto_integral_disponivel: true`, o inteiro teor pode ser lido com jurisprudencia_documento usando o `id`. Alguns registros vêm sem relator/órgão/número quando a publicação não permite afirmar esses campos — campo nulo é ausência de informação na fonte, não defeito. Informe `tribunais` para restringir a busca; sem isso a pesquisa é ampla. Zero resultado não significa que a decisão não exista: costuma ser vocabulário (o termo do tribunal difere do coloquial) ou filtro estreito demais. No termo funcionam os operadores: espaço = E, "entre aspas" = frase exata, OR = ou, -palavra = exclui.
jurisprudencia_documento
Lê o INTEIRO TEOR de uma decisão (texto completo do acórdão, não o resumo). Use o campo `id` de um resultado de jurisprudencia_buscar que traga `texto_integral_disponivel: true` (o `id` já identifica o tribunal, basta repassá-lo), ou o número CNJ do processo. Resultado sem `id` não é legível por aqui, abra a `url`. Quando o processo tem mais de uma decisão, as outras vêm listadas em `outras_decisoes_do_processo`. Bulk support: accepts ids for batched execution.
jurisprudencia_sumulas
Busca SÚMULAS (incluindo vinculantes) por termo. Atalho do jurisprudencia_buscar com tipo=Súmula. Quando o texto completo do enunciado está disponível ele vem na ementa, e enunciado cancelado/revogado é marcado no próprio texto.
authenticate
authenticate
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.
carf
carf_consultar
Consulta processos de uma pessoa ou empresa no Conselho Administrativo de Recursos Fiscais (CARF) a partir do CPF ou CNPJ. Hospedado pela plataforma, sem credenciais, pague por consulta com crédito pré-pago. Consulta informação de ACESSO PÚBLICO em bases e fontes oficiais (a mesma disponível ao cidadão), não é dado privado nem sigiloso. O cliente é o controlador dos dados e responde pela finalidade legítima (LGPD).
connect
connect
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.
marketplace
marketplace
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.
report
report_bug
Report a bug, missing feature, or send feedback. Include the conversation array with recent messages for reproduction.
show
show_version
Show the current MCP platform and adapter versions.
toolkit
toolkit_info
Returns the current toolkit state: installed MCPs, their connection status, the accounts connected to each one, and how many catalog tools each exposes.

CARF (Recursos Fiscais) — questions

Answers built from our own checks of this server.

What can CARF (Recursos Fiscais) do?
It exposes 10 tools, read directly from the server on our last check. Among them: authenticate, carf_consultar, connect, jurisprudencia_buscar, jurisprudencia_documento, jurisprudencia_sumulas and 4 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is CARF (Recursos Fiscais) working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 90 of 92 checks got a reply (97.8%), average response time 2469 ms. The bar chart above shows every period we have measured.
How do I connect CARF (Recursos Fiscais)?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does CARF (Recursos Fiscais) need an API key?
No. CARF (Recursos Fiscais) completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 10 of them are readable on this page. This is what we observed, not what the docs claim.
Is CARF (Recursos Fiscais) open source?
Yes — it is published under the MIT licence and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
