Legal: Litigation Chronology Assembly with Claude Code: MCP Tool Boundary

A production playbook for litigation chronology assembly in legal operations using Claude Code: mcp tool boundary, run-scoped inputs, logs, typed results, and artifacts.

Audience: Litigation teams preparing case timelines

The problem

Litigation teams preparing case timelines need litigation chronology assembly to run repeatedly against pleadings, discovery exports, emails, deposition notes, and evidence folders. In legal operations, the pain is not one good answer; it is repeatability, auditability, exception handling, and evidence that survives handoff.

Implementation path

Expose only the MCP tools needed for litigation chronology assembly, validate tool arguments, keep credentials in the owning service, and log each call outside the sandbox.

Tradeoffs and failure modes

Narrow tool boundaries reduce agent flexibility, but make the integration reviewable and supportable. For litigation chronology assembly, the practical test is whether a second run can be debugged, retried, and consumed by a product without reading the raw agent transcript.
