The MCP gateway
LexCore's verified tools as Model Context Protocol tools for AI apps such as Claude. Built and tested, but not yet open to customers.
The MCP gateway puts LexCore's verified tools behind the Model Context Protocol, the standard way AI apps such as Claude and Cursor call outside tools. Eight tools are built: contract review, single-clause analysis, authority verification (for a whole text or one citation), authority-grounded research, precedent search, and two Nigerian calculators (court deadline and limitation period).
- Implements the core JSON-RPC methods (
initialize,tools/list,tools/call). - Non-negotiable guardrail. Every tool that carries a legal proposition goes through the engine, so CitationGate and the supervision policy apply. An MCP host cannot use LexCore to get an ungrounded answer.
Not available to customers yet
The gateway runs only inside LexCore's own servers. You cannot yet connect Claude, Cursor or another AI app to your LexCore workspace. A public connector that signs in with your LexCore account is planned. To connect other tools today, see Connect LexCore to your other tools.

CitationGate: grounding every finding
A finding with no verifiable quote is rejected, and a quote that doesn't match the source is dropped. This is what makes LexCore's output traceable.
