Documentation Overview
ai-engineering-leader-toolkit
"I just became an engineering manager. What should I focus on?" "What's a healthy sprint completion rate?" "Do I need a mentor or a coach?" "What is this developer worth on the market?" "Should I become a team lead, or stay IC?"
Your AI already gets asked these. Now it can answer with first-party data from 3,400+ paid 1:1 mentoring sessions with 300+ engineering leaders in 17+ countries, instead of guessing.
This is a remote MCP server. No install, no API key. One URL:

Where the data comes from
Every response is grounded in Marian Kamenistak's mentoring practice, not model guesses:
- The calculators mirror the live developer value calculator and engineering manager salary calculator
- The readiness test mirrors the live team lead readiness test
- Benchmarks come from the published engineering leadership statistics, licensed CC BY 4.0
- Playbooks are the actual session templates used across 3,400+ sessions
Nothing is synthetic. Thin topics were cut rather than padded.
Stack
Cloudflare Workers + Durable Objects, McpAgent from the agents SDK, streamable HTTP, authless. GET /mcp with an HTML accept header serves the docs page; MCP clients hit the same URL.
Author
Marian Kamenistak. 20+ years in software, grew Mews engineering 8 to 80 through Series C, now mentors engineering leaders full-time and runs the Engineering Leaders Community in CEE.

A guidance signal from public completeness & health data — not a user rating. New listings start lower and rise as they add docs, get verified, and grow adoption. Signals we can't observe for a listing are skipped, not counted against it.
Supply-chain signal
2 high-severity advisories on record for this package. Most advisories affect transitive dependencies and may not be exploitable in this server's actual usage — this is a directional signal, not a security audit.
