Who it is for
Lawyers running deep legal research against Westlaw and Practical Law.
CoCounsel Legal
Westlaw Deep Research reports with linked Practical Law citations
Overview
What CoCounsel Legal does
CoCounsel Legal is Thomson Reuters's research assistant, and this connector produces Westlaw Deep Research reports inside a conversation.
The distinguishing detail is citation handling: reports carry inline citations linked back to Westlaw and Practical Law sources, so every assertion resolves to material a lawyer can open and check. That link between claim and source is what separates usable legal research from summary. A Thomson Reuters subscription determines access. This connector carries the partner tier, meaning it passed a review step, and documentation is published.
Tool surface
Credentials gate the endpoint, so four is the listing's count. The listing describes report generation rather than naming individual calls.
Availability
Where CoCounsel Legal is listed
CoCounsel Legal is listed in the Claude connectors directory only. Thomson Reuters has no app under the same domain in the ChatGPT directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.
The MCP server behind a Claude connector is usually the same server a ChatGPT app would need, so the absence is a distribution decision rather than a technical one.
Claude listing
In the Claude connectors directory
CoCounsel Legal publishes 4 tools to Claude, a deliberately narrow surface; only 17.2% of the 1,253 Claude-listed connectors expose fewer.
The median Claude-listed connector filed under Productivity publishes 12, so this one sits 8 tools below its bucket's median, 357th of 462.
It falls in the 4-6 tools band, which holds 16.2% of the Claude directory.
CoCounsel Legal publishes a remote MCP endpoint. Claude connects to it over HTTP; there is nothing to install locally.
Every connector in the Claude directory is remote, all 1,253 of them, so transport is not a differentiator there.
