MCP server for eight keyless, no-registration Brazilian open-data APIs:
dadosabertos.camara.leg.br) - the federal legislative
process: bills (proposicoes) as they move through committees and floor votes.legis.senado.leg.br/dadosabertos) -
the real LexML URN Lex resolver for enacted Normas Juridicas (laws, decrees,
constitutional amendments): identification, Diario Oficial da Uniao publication
provenance, amendment history, STF unconstitutionality notes.api-publica.datajud.cnj.jus.br) - court DOCKET metadata (not
ruling text) across STJ/TST/TSE/TRFs/TJs/TRTs/TREs and military courts.dadosabertos.web.stj.jus.br) - real acordao (ruling)
full text + ementa (headnote) from the Superior Tribunal de Justica, Brazil's
second-highest court. Coverage starts May 2022.acordaos.economia.gov.br) - real acordao (tax ruling) full text from
Brazil's federal tax appeals board, by exact docket/decision number.jurisprudencia-backend2.tst.jus.br) - real ruling full text (inteiro
teor) + ementa from the Tribunal Superior do Trabalho, Brazil's labor supreme
court: free-text search and exact CNJ-process-number lookup (3,751,594 acordaos,
8,483,448 documents across all types - verified live 2026-07-07).pesquisa.apps.tcu.gov.br) - real acordao full text (deliberation,
rapporteur's report, vote) from the Tribunal de Contas da Uniao, the Federal
Court of Accounts - public-procurement jurisprudence (525,620 acordaos -
verified live 2026-07-07).br_get_norma resolves a urn:lex:br:... against the Senado's own API gateway
(public, no key or registration) and returns identification, publication provenance,
and amendment history. br_get_norma_index + br_get_norma_texto resolve the same
URN against normas.leg.br's structured Legislation tree for the real text of one
article - not a summary. See DISCOVERY.md for how both endpoints were
found: v0.1.0 tested the wrong host for identification and wrongly reported it as
unconfirmed; v0.2.0 fixed that but still lacked full text; v0.3.0 found the
full-text API on the same domain as the human-readable citation page.
This connector does not scrape Planalto (planalto.gov.br) HTML - no confirmed
mechanical rule maps a URN Lex to a Planalto URL for every act type, and fabricating
one would risk the citation-hallucination failure mode this fleet exists to prevent.
Re-verified live 2026-07-07: legislacao.presidencia.gov.br (the REFLEGIS portal
the manifest names) does not return a plain HTTP response to a keyless client at
all - the connection is accepted but the request times out with zero bytes
received, consistent with a bot-challenge/WAF in front of it, not a structured API.
A minority of act types (mostly decrees) have no inline text in normas.leg.br
either; for those, see DISCOVERY.md.
For case law, DataJud (docket metadata only, redistribution restricted by CNJ
Resolution 446/2022), the STJ Open Data Portal (real acordao text, May 2022+),
CARF (real tax-ruling text, exact lookup only), TST (real ruling text - free-text
search and exact CNJ-process-number lookup, both confirmed live 2026-07-07 after
a browser network trace of the real frontend revealed the request fields the
earlier reverse-engineering missed) and TCU (real acordao/relatorio/voto text)
are wired in below. TRF4/TRF5 were probed and rejected - their hosts never accept
a connection from outside Brazil (geo_restricted) - and RFB's sijut2consulta is
a scrape-class HTML app with no JSON backend. See DISCOVERY.md
for the exact probes run and each confirmed request/response contract.
| Tool | Purpose |
|---|---|
br_search_proposicoes | List bills by type (PL, PLP, PEC, ...) and year |
br_get_proposicao | Full detail + current status for one bill by id |
br_get_norma | Resolve an enacted Norma Juridica by URN Lex - identification, DOU provenance, amendment history, STF notes |

br_get_norma_texto | Fetch the real text of one article (dispositivo) of a Norma |
br_search_processos | Search court dockets (metadata only) in one tribunal's DataJud CNJ index |
br_get_processo | Fetch one court docket by exact CNJ unified process number |
br_search_case_stj | Search STJ acordaos (real ruling text) by process number or free text |
br_get_case_stj | Fetch one STJ acordao by exact process number - ementa + ruling body text |
br_get_case_carf | Fetch one CARF tax acordao by exact docket or decision number - ementa + ruling body text |

br_coverage | Declare what this connector covers, when each family was captured, and - explicitly - what it does NOT cover. Every gap carries a fallback. |
Bill type codes (sigla_tipo), for reference:
| Code | Portuguese | English |
|---|---|---|
PL | Projeto de Lei | ordinary bill |
PLP | Projeto de Lei Complementar | complementary-law bill (implements a constitutional provision) |
PEC | Proposta de Emenda a Constituicao | constitutional amendment proposal |
Every response carries lex_uri, human_readable_citation and source_url.
For br_search_proposicoes/br_get_proposicao, lex_uri is Camara's own stable
API URI (not a URN Lex - a bill isn't enacted law yet). For br_get_norma,
lex_uri is the real urn:lex:br:... you queried with, e.g.
"urn:lex:br:federal:lei:2002-01-10;10406" (Codigo Civil). For br_get_norma_texto,
lex_uri is that URN plus the article suffix, e.g. "...;10406!art5".
Smart App Control blocks unsigned executables, which covers uvx.exe, pip.exe
and the br-eli-mcp.exe launcher that pip writes at install time. The python.exe and
py.exe from the python.org installer are signed by the Python Software
Foundation, so running the module through the interpreter works:
pip.exe is blocked for the same reason, so install with python -m pip, not
pip install. If python is not on PATH, use the Windows launcher: py -3 -m br_eli_mcp.
Do not turn Smart App Control off to work around this - it cannot be re-enabled without reinstalling Windows.
