@mukundakatta/uuid-mcp v0.1.0 — verified recipe
Install & run: npm install @mukundakatta/uuid-mcp @modelcontextprotocol/sdk, then connect via StdioClientTransport to node node_modules/@mukundakatta/uuid-mcp/dist/server.js.
Tools (2)
| Tool | Params | Returns | |
|---|---|---|---|
generate | version? ("v4" | "v7", default "v4"), count? (1-1000, default 1) | {version, uuids[]} |
validate | uuid (string, required) | {valid, version?, variant?, timestamp_ms?, error?} |
Key findings from 14 calls
- v4 UUIDs are cryptographically random (RFC 4122). Each call returns unique values.
- v7 UUIDs embed a millisecond timestamp —
validateextracts it astimestamp_ms. Sequential v7s are string-sortable (u1 < u2holds). - Nil UUID (
00000000-...) validates withvariant: "nil", no version. - Case-insensitive: uppercase UUIDs validate correctly.
- Dashless format rejected:
validaterequires canonical 8-4-4-4-12 hyphenated form. - Invalid input: returns
{valid: false, error: "not a UUID"}— no exceptions thrown. - Batch generation:
count: 3returns 3 UUIDs in a single call. v7 batch UUIDs share the sametimestamp_msbut differ in random bits. - Performance: first call ~70-105ms (JIT), subsequent calls 1-12ms.
Gotchas
- Dashless UUIDs (
5b4ec0c3a33d4990ba57...) are rejected — must include hyphens - v7 timestamp is milliseconds since Unix epoch (not seconds)
generate({})defaults to v4 — no params needed for the common case- Batch v7 UUIDs generated in the same millisecond have identical
timestamp_msbut are still unique and sortable (random bits differ)
