Cadastro Ambiental Rural: Demonstrativo (PDF), official-source lookup. Platform-hosted, pay per quer
Scored across 7 tools
Tools are mostly distinct: authentication, connection status, marketplace search, bug reporting, version info, toolkit status, and a single CAR PDF query tool. Minor overlap exists between 'authenticate' and 'connect', but their purposes are clear enough to avoid confusion.
Naming is inconsistent: most tools use English imperative verbs (authenticate, connect, report_bug), but the domain tool uses Portuguese with a different structure (car_demonstrativo_pdf_consultar). Mixing languages and verb patterns reduces predictability.
With 7 tools, the count is within the acceptable 3-15 range. However, several tools (marketplace, show_version, toolkit_info) are generic platform utilities rather than directly serving the CAR PDF domain, making the set feel slightly bloated for a single-purpose server.
For the stated purpose of querying CAR demonstrativo PDFs, the single domain tool (car_demonstrativo_pdf_consultar) covers the core operation. Missing additional operations like listing or deleting are not implied by the domain, so completeness is adequate, though the server lacks any auxiliary domain functions.
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: "" } after the user pastes, or with no args to get the link.
Inputs: token.
Cadastro Ambiental Rural: Demonstrativo (PDF), consulta em fonte oficial. Hospedado pela plataforma, sem credenciais da plataforma, pague por consulta com crédito pré-pago. Consulta informação de fontes e órgãos oficiais brasileiros (a mesma disponível ao cidadão), não é dado sigiloso. O cliente é o controlador dos dados e responde pela finalidade legítima (LGPD).
Inputs: car (required).
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.
Inputs: no named parameters.
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/ link that opens without login.
Inputs: limit, query, action, mcp_id, +19 more.
Report a bug, missing feature, or send feedback. Include the conversation array with recent messages for reproduction.
Inputs: message (required), context, conversation.
Show the current MCP platform and adapter versions.
Inputs: no named parameters.
Returns the current toolkit state: installed MCPs, their connection status, the accounts connected to each one, and how many catalog tools each exposes.
Inputs: no named parameters.
