Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (20)

`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.
`b3_get_carteira`read-only	Resumo da carteira agrupado por classe de ativo (ações, FIIs, renda fixa, etc.) com valor e percentual de cada grupo.
`b3_get_evolucao_patrimonial`read-only	Série histórica de evolução do patrimônio na B3.
`b3_get_patrimonio`read-only	Patrimônio total consolidado na B3 (soma de todas as corretoras) numa data. Retorna { valor, data }.
`b3_get_perfil`read-only	Cadastro/perfil do investidor (identidade da conta B3 conectada).
`b3_get_posicao`read-only	Posição DETALHADA por ativo numa data: ticker (codigoNegociacao), quantidade, preço de fechamento, valor atualizado, ISIN, instituição. Agrupado por tipo de produto. Paginado.
`b3_get_ultima_atualizacao`read-only	Data/hora da última carga de dados da B3 (a base é D-1). Use para saber quão fresca está a posição.
`b3_list_accounts`read-only	Lista as contas da Área do Investidor B3 conectadas a este install — id, label.
`b3_list_ativos`read-only	Drill-down nos ativos de UM tipo de produto (informe `codigoProduto`), com valor e percentual de cada ativo do grupo. Para a posição COMPLETA de todos os ativos, use b3_get_posicao.
`b3_list_instituicoes`read-only	Instituições (corretoras) vinculadas ao investidor na B3.
`b3_list_movimentacao`read-only	Movimentação de ativos (entradas/saídas: transferências, subscrições, bonificações, etc.) num intervalo. Paginado.
`b3_list_negociacoes`read-only	Negociações (compras/vendas) num intervalo de datas. Paginado por `page`.
`b3_list_ofertas_publicas`read-only	Ofertas públicas (IPOs/subscrições) do investidor num intervalo. Paginado por `page`.
`b3_list_proventos_a_receber`read-only	Proventos provisionados a receber (dividendos/JCP futuros) numa data de referência.
`b3_list_proventos_recebidos`read-only	Proventos já recebidos (dividendos/JCP pagos) num intervalo de datas. Paginado.
`connect`read-only	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`	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_bug`	Report a bug, missing feature, or send feedback. Include the conversation array with recent messages for reproduction.
`show_version`read-only	Show the current MCP platform and adapter versions.
`toolkit_info`read-only	Returns the current toolkit state: installed MCPs, their connection status, the accounts connected to each one, and how many catalog tools each exposes.

Schemas: list_tools.
