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:

Tools
| Tool | The question it answers |
|---|---|
calculate_developer_value | What is this developer worth? Scores 15 skills across 5 pillars, returns level + 2026 Western-Europe salary estimate |
calculate_engineering_manager_value | What is this engineering manager worth? Scores 15 leadership skills across 5 pillars, weighted by level, returns Team Lead → Director/VP level + 2026 Western-Europe salary estimate |
assess_team_lead_readiness | Should I become a team lead? 17 questions, 6 dimensions, a straight verdict (ready now / 6-12 months out / stay IC) + top-2 gaps with one move each |
get_engineering_leadership_benchmarks | What's healthy? Sprint completion, roadmap %, manager time per report, mentee mix, 2025 topic demand. CC BY 4.0, citable |
choose_mentor_coach_or_advisor | Mentor, coach, or advisor? All three compared + a three-question self-test |
get_one_on_one_playbook | How do I run this 1:1? Real session templates: first session, underperformance, promotion to EM, better 1:1s, career move |

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.
