Everlaw Connects Case Data to Claude Through an MCP Integration

What the integration does

Claude can now reach Everlaw case data through MCP, which lets users apply Claude within what Christoff calls "a precisely sanctioned workspace." MCP is an open standard created by Anthropic that allows a wide variety of tools and models to work together. Christoff compares it to USB, which largely standardized a prior mess of different cables and plugs.

According to Christoff, the launch rests on two technical advances: more capable reasoning models that can plan multi-step actions, and the ability of models to use tools, especially via MCP. Everlaw says the integration brings the agentic architecture of Claude Cowork into the way legal professionals already work.

The integration launches as part of Claude for the legal industry, which Christoff describes as an initiative with practice-area plugins and partner-contributed skills, while advancing access to justice.

An example from an antitrust case

Christoff gives the example of an associate drafting a brief for an energy antitrust case. The associate opens a Claude window and describes the desired outcome: "Visualize the volume of documents containing the words 'set prices,' grouped by year."

According to Everlaw, Claude then takes several steps:

• It develops a plan, asking follow-up questions if the request is unclear, breaking the outcome into subtasks and parallel workstreams, and identifying the information it needs.
• It checks that it has the tools required, gathers technical documentation on how to use Everlaw, and invokes a set of Everlaw requests via MCP to run searches and access documents.
• It works with full transparency and presents its output, perhaps in a bar chart it designs itself.

The associate can see Claude's reasoning at each step and adjust the request, for instance by asking to see the data in a pie chart instead. Without the integration, Christoff says, the associate would run several searches for different terms and date ranges in Everlaw, export the data into Excel and build multiple charts. Claude does it all, he says, in less than a minute.

Security and system of record

Everlaw says it strictly enforces access to documents through its existing security controls. A user working with Everlaw materials via Claude has no more permissions or access than they would in the Everlaw web application. Everlaw also remains the system of record for case materials and review.

Christoff says the integration lets customers connect Everlaw to broader AI workflows without the risks of leaky exports, fragmented systems, or losing the permissions and governance they rely on.

What it means for legal teams

Christoff notes that law firms are already building customized, complex processes on platforms such as Claude. With the integration, they can reach an industry-standard partner like Everlaw for system of record case information from within those workflows.

He calls the launch "the first step of many to building truly agentic legal workflows." The post does not give pricing or availability details.
