Relex vs Harvey
What this product is for
Harvey provides legal AI workflows and supports external MCP servers, including administrator-enabled custom servers with per-user authorization.
Why add—or choose—Relex
Choose Relex when you want the saved legal matter to remain available to different compatible assistants. Harvey may be one of those clients where its requirements and your deployment permit; this is not a claim of Harvey partnership or connector approval.
What to verify before choosing
Test the full handover rather than MCP availability alone: can another authorized assistant retrieve saved facts and conclusions? Check minimum scopes, server-side write safeguards and token revocation. Do not rely on Harvey always prompting before writes.
Benchmark protocol: prove the handover, not the slogan
