Dados Abertos Senado BR MCP

Vídeos da taquigrafia

senado_videos_taquigrafia

Read-onlyIdempotent

Lista os vídeos e áudios (unidades descritivas) de uma sessão plenária ou reunião de comissão. Retorna { id, tipo, count, total, aviso?, videos } (sessão sem mídia no acervo → count/total 0 com aviso; ao passar de limite inclui aviso). A cobertura de mídia é mais ampla que a das notas: sessões conjuntas do Congresso costumam ter vídeos mesmo sem transcrição, cada item com codigo, data, descricao, orador, duracaoSegundos e os links urlVideo, urlAudio, urlThumbnail. Obtenha o id via senado_agenda_plenario/senado_resultado_plenario (sessão) ou senado_reuniao_comissao (reunião). Para a transcrição textual correspondente use senado_notas_taquigraficas, não esta.

Input Schema

Name	Required	Description	Default
`id`	Yes	Código da sessão plenária ou da reunião de comissão, conforme `tipo`
`tipo`	No	sessao = plenário (padrão); reuniao = comissão	sessao
`limite`	No	Máximo de unidades (padrão 50, máx 200); o excedente é sinalizado em aviso
`orador`	No	Retorna só unidades cujo orador contém este nome (busca parcial)

Output Schema

Name	Required	Description	Default
`provenance`	Yes	Bloco de proveniência do portfólio (projeção concise): source, source_url, data_vintage, retrieved_at (horário de Brasília), citation, license, revision e retrieval; field_sources só quando a resposta funde recortes, derived e derivation_note só nos modos de estatísticas. retrieval é o diagnóstico da ida à origem nesta chamada — requisições, tentativas com retentativas, anomalias superadas (timeout, network, rate_limited, http_5xx, http_4xx, malformed_body) e unstable (true quando algo precisou ser repetido) —, ou null quando não foi medido. Lista de blocos quando a chamada consulta várias fontes (índice do search).
`attribution`	Yes	URLs de origem dos dados (as source_url distintas dos blocos de proveniência, incluindo as de field_sources), para linkar a citação

A4.8/5.0

Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Beyond the readOnly/idempotent annotations, the description discloses non-obvious behavior: empty-media sessions return count/total 0 with an aviso, exceeding limite also emits an aviso, and media coverage is broader than transcription (joint Congress sessions often have video but no transcript). These are substantive traits the annotations cannot convey.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Purpose is front-loaded and sentences are substantive, though the response-shape sentence is quite dense with inline parentheticals. It remains efficient and wastes little, but the middle is information-heavy enough to require careful parsing.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a read-only listing tool with full schema coverage, annotations, and an output schema, the description covers everything an agent needs: what it returns, the empty/overflow warnings, the data source for id, and the sibling boundary. Nothing material is missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the parameters are documented structurally; the description still adds value by explaining that id is a session/reunion code whose source depends on tipo. It does not expand on the orador partial-match or the limite cap beyond what the schema already states, so it sits above baseline but not at the top.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The opening sentence names a specific verb and resource ('Lista os vídeos e áudios (unidades descritivas) de uma sessão plenária ou reunião de comissão') and the closing sentence explicitly demarcates it from the sibling senado_notas_taquigraficas. An agent can distinguish it from the transcription tool without opening either schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It states exactly how to obtain the required id ('via senado_agenda_plenario/senado_resultado_plenario (sessão) ou senado_reuniao_comissao (reunião)') and names the alternative to use when the goal is the textual transcript. Both the when and the when-not are explicit.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
