How to Use the LEAP Legal MCP in Cursor

Q: How do I test contact creation in LEAP Legal using Cursor?

Use the createnewcard tool within Cursor's agent mode. The MCP server lets you pass a test JSON payload to insert a contact card and verify the response immediately.

Q: Can Cursor read my active case documents from LEAP Legal?

Yes. Cursor uses getmatterdocumentsonly to fetch the file list and getmattercorrespondence to pull emails and letters linked to a specific matter ID.

Q: How do I list case records using LEAP Legal in Cursor?

Run listmatters in Cursor's chat or agent mode to get a list of active matter IDs. You can then pass these IDs to other tools to inspect case details.

Q: How do I find linked contacts for a specific matter?

Use getmatterlinkedcards with a valid matter ID. The tool returns all contacts, experts, and opposing parties associated with that specific legal file.

Perplexity

Write Legal Code with Live LEAP Matter Context

The `get_matter_details` tool feeds real case structures directly into Cursor so your AI agent writes code using live API responses. Instead of guessing the JSON payload, the editor reads the actual properties returned by your active matters. You write scripts to automate document generation or billing exports while Cursor checks your code against real data. This prevents runtime errors and eliminates the need for mock databases during development.

Automate Contact Management in Cursor

The `create_new_card` tool allows Cursor to write and test contact creation scripts using real client profiles. This MCP server lets your AI agent call `list_cards` to check for duplicates before writing logic that inserts new organizations or individuals. This setup lets you build custom intake forms that write directly to your legal database. You test the integration in real-time inside Cursor, ensuring every field maps correctly to the LEAP database schema.

Extract Case Documents for Custom Workflows

The `get_matter_documents_only` tool pulls actual PDF and Word file lists into Cursor to help you build custom document pipelines. The AI agent analyzes the files returned by `get_matter_correspondence` to map out case histories. You write parsers or backup scripts using real file paths and metadata. This MCP integration lets you write parsers directly in the editor without manually downloading test files.
