Our reading of Komplyt Zero, from the data

Komplyt Zero is a memory MCP server from komplyzen, listed in the official MCP Registry.

Its endpoint requires sign-in or an API key just to list tools, so we haven't measured its token cost; we never use real credentials.

Maintenance is active: the last public signal was in the last day (2026-10-18). For comparison, 68% of memory servers are active or maintained.

With 14 GitHub stars it ranks #284 of 1,597 memory servers we index.

It runs either locally over stdio or as a hosted endpoint and needs 3 secrets (KG_DB_PASS, KG_JWT_SECRET, EMBEDDING_API_KEY); use a scoped, least-privilege key.

Install Komplyt Zero MCP server

claude mcp add src-komplyzen -e KG_AUTH_MODE='<kg-auth-mode>' -e KG_DB_URL='<kg-db-url>' -e KG_DB_USER='<kg-db-user>' -e KG_DB_PASS='<kg-db-pass>' -e KG_JWT_SECRET='<kg-jwt-secret>' -e EMBEDDING_API_KEY='<embedding-api-key>' -- npx -y @komplyzen/komplyt-zero mcp

Deductions

No findings from the checks that ran.

Checks

✓Repository hygiene (archived, activity, license, security policy)
○Package metadata (install scripts, provenance) — pending
○Tool descriptions (prompt-injection and hidden-text heuristics) — pending
○Source scan (secrets, CVEs, risky code) by vectra-guard — pending
