MCP connector

Lexiel for your AI

You do not have to change tools. Claude and ChatGPT are already open on your screen: what they lack is a source that does not invent judgments. That is what you connect here.

Three things you can do today

They all start the same way: you type in the chat you already use, and the answer comes back with its ECLI and its link.

Verified case law from ChatGPT

ChatGPT

"Find Supreme Court judgments on dismissal for absenteeism since 2023 and tell me the current doctrine."

ChatGPT searches CENDOJ through Lexiel and answers with real ECLIs, not with the ones that sound right. Every judgment it cites exists and can be opened. The connector gives it the search and fetch tools, which are exactly the ones ChatGPT knows how to use to research.

Draft with citations from Claude

Claude

"Draft the third legal ground on the nullity of the floor clause and verify every citation before giving it to me."

Claude writes the brief and, before handing it over, runs every citation through Lexiel. The ones that do not exist are flagged instead of slipped in. Paste a brief you already wrote and it audits the citations one by one and tells you which ones do not hold.

Query case files from Claude Code

Claude Code

claude mcp add --transport http lexiel https://api.lexiel.ai/mcp/stream

In the terminal, with one command. Useful if you automate: cross-check a batch of references against CENDOJ, verify procedural deadlines across a set of matters, or audit the citations of every brief in a file without opening a browser.

Connector plan

The connector works on every plan, the free one included, with 40 queries a day. The Connector plan removes the daily cap and gives 300 queries a month; and it already comes included, at no extra cost or cap, on the Básico, Profesional and Firma plans.
