The MCP gateway
Expose LexCore's verified capabilities as Model Context Protocol tools any AI host can call — without bypassing CitationGate.
The MCP gateway exposes LexCore capabilities — review, extract, compare, redline, verify, research — as Model Context Protocol tools, so any MCP host (Claude, Cursor, and others) can call the verified backend. It turns the emerging "legal skills marketplace" into a distribution channel: a shallow skill that calls these tools inherits LexCore's whole verification story.
- Implements the core JSON-RPC methods (
initialize,tools/list,tools/call) over a transport-agnostic handler. - Non-negotiable guardrail — every tool that carries a legal proposition routes through the engine, so CitationGate and the supervision policy apply. An MCP host cannot use LexCore to get an ungrounded answer.
Note
The gateway is live; consuming third-party MCP servers (for connectors) and the official SDK transport are follow-ons.

CitationGate: grounding every finding
The trust core. A finding with no verifiable quote is rejected; a quote that doesn't match the source is dropped. This is why LexCore's output is traceable.
