How to Use the Legal Deadline Calculator Engine MCP in Cursor

Q: How do I add the Legal Deadline Calculator Engine to my Cursor project as an MCP Server?

Create a .cursor/mcp.json file in your project root. Add the server configuration under the mcpServers block, and Cursor will automatically start the tool when you open the workspace.

Q: Can the Legal Deadline Calculator Engine in Cursor help me write unit tests?

Yes. Your agent can call the calculatelegaldeadline tool to obtain ground-truth dates. It then writes test assertions using those exact, mathematically verified dates to cover your code's edge cases.

Feed mathematically perfect court dates directly into your legal applications using Cursor and this MCP Server.

Generate accurate date logic in Cursor Agent

The `calculate_legal_deadline` tool gives your Cursor Agent a deterministic engine for computing procedural timelines. Instead of writing flaky JavaScript date math or relying on LLM guesses, the agent queries the tool to get verified dates. This means your generated code uses real, tested date calculations. The agent can write unit tests based on the actual outputs of the tool, ensuring your application logic matches court rules.

Local development integration via project MCP Server

The `calculate_legal_deadline` tool integrates directly into your editor via a local `.cursor/mcp.json` file. This lets you run the calculation engine as a background process while you build your legal tech tools. Your agent can call the tool to verify date calculations on the fly. You do not need to spin up external APIs or mock date databases during your development cycle.

Deterministic business day counting for codebases

The `calculate_legal_deadline` tool eliminates the need to write complex rollover logic for weekends and holidays in your application. The tool manages the counting mechanics, skipping Saturdays and Sundays automatically. By using this server, your Cursor Agent can verify that your software's deadline calculations match standard federal statutory requirements. It provides a reliable benchmark for testing your own date-handling functions.
