What becomes possible

One agent workflow across the systems your firm already uses.

01 Onboarding

Engagement letter → live matter

Prepare the client, matter, rates, and retainer request from a signed engagement letter, with review before anything is saved.

Sample prompt

“Set up this client and matter in LeanLaw from the signed letter. Show me everything before you save.”

02 Client picture

Money and work, in one brief

Bring LeanLaw balances and unbilled work together with recent conversations before a client meeting.

Sample prompt

“Brief me on Henderson using LeanLaw, the latest email, and recent Teams threads.”

03 Time capture

Reconstruct the day

Draft time from calendar, email, and document activity, map it to matters, and keep a person in the review step.

Sample prompt

“Draft today’s time, add UTBMS codes, and let me review it before posting.”

Examples of agent workflows firms are exploring — not a feature roadmap.

Embedded AI

ClerkAI

Ask plain-language questions about your firm’s LeanLaw data, including complex questions that are hard to pull from standard reports. ClerkAI is early and read-only today.

Agent-ready

Public API + MCP

Make LeanLaw usable by your firm’s own AI across a connected workflow. The public API is available today, and the MCP layer is in private beta.

Frequently asked questions

What’s live, early, and in beta.

Is LeanLaw’s MCP server available?

It’s in private beta. MCP is an open standard governed by the Linux Foundation’s Agentic AI Foundation.

Does LeanLaw use AI?

Yes, in two ways. Embedded AI features inside the product — like ClerkAI, which answers plain-language questions about your firm’s data — and agent-readiness: making LeanLaw work with a firm’s own AI agents through our API and an MCP layer, currently in private beta.

What is Agent Experience (AX)?

An emerging discipline — tracked by Gartner alongside more established fields like developer experience — for designing products so AI agents acting on a user’s behalf can reliably use them. LeanLaw’s MCP work is our implementation of it.

What is ClerkAI?

LeanLaw’s natural-language assistant for asking questions about your firm’s data, especially complex questions that are hard to pull from standard reports. It’s early and read-only today.

Does LeanLaw train AI on client data?

No. LeanLaw uses third-party AI providers that don’t train on customer data without permission, and we don’t grant it. We don’t sell client data.
