Best Legal MCP Servers

MCPpedia tracks 510 legal MCP servers. 175 of them score at least 50 out of 100, and 90 clear 70 - about 18% of what has been published in this space. The remaining 335 are thinner: registry entries with no description, no published tool schema, or no commit in the last year. They are all still listed here, because knowing a server exists and is unmaintained is worth as much as knowing a good one exists.

Korean Law MCP leads the list at 93/100. io.github.pipeworx-io/jpo-patent-info (89) and io.github.pipeworx-io/kentucky-code (89) follow. Every score is the same five weighted inputs: security (CVE scanning, tool-poisoning detection, and whether the server authenticates at all), maintenance (commit recency, release cadence, and download trend), documentation, client compatibility, and token efficiency - how much of your context window the tool definitions consume before you have asked anything.

1 of these servers are published by the vendor behind the underlying API rather than by a third party, which is usually the difference between an integration that tracks upstream changes and one that quietly stops working. None currently carry an open CVE, though that is a snapshot - advisories are re-scanned daily.
