Add Brazilian legal MCP (Letra da Lei) as external plugin and connector

[juliolinstech]

Letra da Lei is the Brazilian legal platform — search and retrieve statutes, codes, and regulations with article-level citations and verified source links.

Server: https://api.letradalei.com/mcp
Auth: None required (rate-limited by IP)
Transport: Streamable HTTP (stateless)

What this adds

• external_plugins/letra-da-lei/ — full external plugin with plugin.json, .mcp.json, README.md, and one skill (pesquisa-legislacao)
• marketplace.json — letra-da-lei entry
• Main README.md — directory listing, external plugins table, connectors table, skills section

Tools

Tool	Type	What it does
buscar_legislacao_federal	Read	Semantic + full-text search across the legal corpus; returns verbatim article text, citation IDs, and Planalto.gov.br source links
listar_legislacao_federal	Read	Lists all laws in the corpus with identifiers, thematic groupings, and source URLs

Both tools return retrieved_at and source_indexed_at for provenance. Results include no instruction-like content. Errors fail fast with clean messages and Retry-After headers on 429s.

Practice areas

Best fit for Brazilian legal practitioners across any practice area. Most relevant as a standalone plugin (letra-da-lei) for users working with Brazilian law — statute lookup, citation verification, and legal research grounded in official sources.
