# 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 |
| `get_first_time_manager_guidance` | I'm a new EM, now what? The responsibility triangle, six failure modes, readiness self-check |
| `build_mentoring_business_case` | How do I get my company to pay for mentoring? Manager email (learning-budget or no-budget version), Slack short, talking points, a one-pager for finance, objections answered, napkin math — EN or CZ |
| `estimate_coaching_cost` | How much should a coach cost me? Fair per-session range + program total by coaching type, role, territory, and coach seniority — ICF 2025 + CEE market anchors, with red flags |
The business-case tool also has a plain JSON surface for the marian.coach pricing-page wizard, same core, same output: `GET https://www.marian.coach/mcp/business-case?lang=en|cs` returns the wizard options, `POST` with the tool's input JSON returns the structured case.

## 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](https://www.marian.coach/developer-salary-calculator/?ref=github) and [engineering manager salary calculator](https://www.marian.coach/engineering-manager-salary-calculator/?ref=github)
- The readiness test mirrors the live [team lead readiness test](https://www.marian.coach/team-lead-readiness-test/?ref=github)
- Benchmarks come from the published [engineering leadership statistics](https://www.marian.coach/engineering-leadership-statistics/?ref=github), 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](https://github.com/cloudflare/agents) SDK, streamable HTTP, authless. `GET /mcp` with an HTML accept header serves the docs page; MCP clients hit the same URL.
```bash
npm install
npx wrangler dev # local
npx wrangler deploy # ship it
```
