## Quality 88/100 (good)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-11-25; 2026-07-28 not supported, older versions are deprecated until 2027-07-28

- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 93 (weight 30)

- pass `tools.descriptions`: every tool has a description
- warn `tools.description_length`: 1 tools have descriptions over 1,024 characters, which crowds the context
- pass `tools.schemas`: every tool has an object input schema
- pass `tools.annotations`: 20 of 20 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 2,698 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: no tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 20, about 2,698 tokens to load them all
- tool set hash: bb9b579212c7e202b90b3b7fa5455c67
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.mcp-dir/b3-mcp.svg)](https://protogrid.dev/servers/io.github.mcp-dir/b3-mcp)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## 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`: Resumo da carteira agrupado por classe de ativo (ações, FIIs, renda fixa, etc.) com valor e percentual de cada grupo.
- `b3_get_evolucao_patrimonial`: Série histórica de evolução do patrimônio na B3.
- `b3_get_patrimonio`: Patrimônio total consolidado na B3 (soma de todas as corretoras) numa data. Retorna { valor, data }.
- `b3_get_perfil`: Cadastro/perfil do investidor (identidade da conta B3 conectada).
- `b3_get_posicao`: 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`: 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`: Lista as contas da Área do Investidor B3 conectadas a este install — id, label.
- `b3_list_ativos`: 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`: Instituições (corretoras) vinculadas ao investidor na B3.
- `b3_list_movimentacao`: Movimentação de ativos (entradas/saídas: transferências, subscrições, bonificações, etc.) num intervalo. Paginado.
- `b3_list_negociacoes`: Negociações (compras/vendas) num intervalo de datas. Paginado por `page`.
- `b3_list_ofertas_publicas`: Ofertas públicas (IPOs/subscrições) do investidor num intervalo. Paginado por `page`.
- `b3_list_proventos_a_receber`: Proventos provisionados a receber (dividendos/JCP futuros) numa data de referência.
- `b3_list_proventos_recebidos`: Proventos já recebidos (dividendos/JCP pagos) num intervalo de datas. Paginado.
- `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`: 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`: Show the current MCP platform and adapter versions.
- `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.
