Integration details

Description

The Harvey plugin connects ChatGPT to Harvey's AI-powered legal intelligence platform. It supports three core capabilities: (1) General legal inquiries grounded in Harvey's legal knowledge; (2) Analysis and search over your firm's Vault projects — saved work product, memos, and prior documents; (3) Targeted research using specialized knowledge sources, such as UK Tax legislation and HMRC manuals. Discovery tools let users list available Vault projects and knowledge sources. All tools are read-only and operate strictly within the authenticated user's Harvey permissions. Access requires a Harvey account with an active license and the MCP feature enabled by your workspace admin.

How do I improve a ChatGPT Plugin's discoverability?

The levers are the listing surface agents actually read: names, descriptions, keywords, tool metadata, and registry health. Which lever matters depends on where discovery breaks, which is what continuous measurement shows.
