Who it is for
Brazilian lawyers researching precedent, contrary authority and consolidated legislation.
Brazilian case law and legislation ranked by legal authority
Overview
Jusratio indexes over 40 million deduplicated decisions from 97 Brazilian courts and public authorities, alongside consolidated legislation structured article by article. Deduplication matters at that scale, since the same decision often appears through several channels.
Results are ranked by legal authority and linked to their original sources. The listing describes the work it supports in the terms a Brazilian practitioner would use: finding binding precedent, validating an argument, identifying contrary authority, comparing positions between courts, and drafting opinions and briefs with citations that can be checked. A free account is available. Community tier, documentation published.
Brazilian lawyers researching precedent, contrary authority and consolidated legislation.
Credentials are required first, so eleven is the listing's count. Decision search, consolidated legislation lookup article by article, and authority ranking are the groupings described.
Availability
Jusratio BR is listed in the Claude connectors directory only. Jusratio has no app under the same domain in the ChatGPT directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.
The MCP server behind a Claude connector is usually the same server a ChatGPT app would need, so the absence is a distribution decision rather than a technical one.
Claude listing
Jusratio BR publishes 11 tools to Claude. That is a mid-sized surface: 48% of the 1,253 Claude-listed connectors expose fewer.
That is exactly the median for Claude-listed connectors under Legal, where 33 publish counts and 11 is the middle of the distribution.
It falls in the 11-20 tools band, which holds 22.5% of the Claude directory.
Jusratio BR publishes a remote MCP endpoint. Claude connects to it over HTTP; there is nothing to install locally.
Every connector in the Claude directory is remote, all 1,253 of them, so transport is not a differentiator there.
https://mcp.jusratio.com.br/mcp Jusratio BR is community-listed in the Claude directory, the tier 770 of 1,253 connectors sit in (61.5%). It is the default for a self-published server, and says nothing either way about quality.

Node8 builds MCP servers end to end: deciding which tools are worth exposing, the authentication and permission model, the review submissions, and the onboarding that gets them used. One server serves ChatGPT, Claude, and Microsoft Copilot.
