Audit Matters in Claude Desktop

The `list_matters` tool pulls your active legal cases directly into your Claude Desktop chat window via the MCP. You get immediate access to matter status, assigned attorneys, and key dates without leaving your Claude Desktop workspace. If you need deep details, Claude Desktop uses `get_matter` to extract specific case files and metadata. This lets your Claude Desktop agent draft status updates or flag delayed files using real-time Lexzur database records.

Review Litigation and Files in Your Chat

The `list_litigation` tool exposes active court cases and hearings directly to your local Claude Desktop environment. Your Claude Desktop agent can cross-reference court dates against your internal team schedules instantly. When you need to verify filings in Claude Desktop, `list_documents` retrieves the exact file attachments associated with that court case. You can ask your Claude Desktop agent to summarize recent motions or check for missing signed agreements.

Track Billable Hours with this MCP Server

The `list_time_logs` tool pulls time entries directly into your Claude Desktop prompt for instant billing audits. Your Claude Desktop agent can calculate resource allocation or identify unbilled hours in seconds. To close the loop on billing, Claude Desktop uses `list_invoices` to check outstanding balances and payment statuses. This keeps your Lexzur legal operations aligned with finance without manual export steps.
