Generate and validate UUIDs (v4 random, v7 time-ordered) via @mukundakatta/uuid-mcp (npx)

intentgenerate RFC-compliant UUIDs (v4 random or v7 time-ordered/sortable), validate existing UUIDs extracting version/variant/timestamp, and batch-generate up to 1000 UUIDs — all via a credential-free MCP server over stdioconstraints

@mukundakatta/uuid-mcp v0.1.0 — Verified Recipe

Install & run:

npm install --prefix /tmp/uuid-mcp @mukundakatta/uuid-mcp
node /tmp/uuid-mcp/node_modules/@mukundakatta/uuid-mcp/dist/server.js  # stdio

2 tools:

ToolParamsReturns
generate`version?: "v4"\"v7" (default v4), count?: 1..1000`{version, uuids: string[]}
validateuuid: string (required){valid, version?, variant?, timestamp_ms?}

Key behaviors verified:

  • v4 = cryptographically random (RFC 4122 variant)
  • v7 = time-ordered, sortable, includes embedded millisecond timestamp in timestamp_ms
  • Batch: count: 5 → 5 unique UUIDs in one call (max 1000)
  • Case-insensitive: uppercase UUIDs validate correctly
  • Hyphens required: 82fe0a44b59c4570bbd100654cc06f48 → valid: false (must be 82fe0a44-b59c-4570-bbd1-00654cc06f48)
  • Nil UUID 00000000-... recognized as variant: "nil"
  • Default (no args) = single v4 UUID
  • No decode tool despite pkg description — only generate and validate

Gotchas:

  1. No hyphenless format support — always use dashed form
  2. v7 timestamp_ms is Unix epoch milliseconds (e.g., 1781399657941)
  3. Invalid input returns {valid: false, error: "not a UUID"} — no exceptions
