Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

calculate

calculate_developer_value

Assess a software developer's market value: score 15 skills across 5 pillars (core craft, systems & judgment, impact & ownership, collaboration & influence, AI leverage), get a weighted total score, seniority level, and a 2026 Western-Europe gross salary estimate. Same logic as the live calculator at marian.coach. Unscored skills default to the level's baseline.

calculate_engineering_manager_value

Assess an engineering leader's market value: score 15 leadership skills across 5 pillars (people & talent, delivery & execution, technical direction, stakeholder influence, AI leverage), weighted by current level, get a total score, a level from Team Lead to Director/VP of Engineering, and a 2026 Western-Europe gross salary estimate. Same logic as the live EM salary calculator at marian.coach. Unscored skills default to the level's baseline.

assess

assess_team_lead_readiness

Answers "should I become a team lead?" with the same 17-question test as the live tool at marian.coach: 6 dimensions (people appetite, letting go of code, ownership beyond your tickets, translation & saying no, motivation, org reality), a straight verdict — ready now / 6-12 months out / stay IC (and that's fine) — plus the top-2 gap dimensions with one concrete move each. Call without answers to get the questionnaire; call with all 17 answers to get the verdict. Built from 3,400+ mentoring sessions.

build

build_mentoring_business_case

Build the business case to get your company to pay for leadership mentoring or coaching: computes the ROI in EUR (money saved + cost of delay avoided + missed opportunity + roadmap slippage avoided), suggests 3-6 month KPIs, and drafts a forwardable approval email for your manager. Based on 3,400+ mentoring sessions at marian.coach.

choose

choose_mentor_coach_or_advisor

Decide whether an engineering leader needs a mentor, a coach, or an advisor: what each brings, the typical question each answers, whether domain experience is required, time horizon, and a three-question self-test. Based on 3,400+ mentoring sessions.

engineering

get_engineering_leadership_benchmarks

Real benchmarks from 3,400+ paid 1:1 mentoring sessions with 300+ engineering leaders since 2019: mentee seniority mix, most-demanded leadership topics of 2025, time-to-results, team-health delivery thresholds (sprint completion, roadmap %, manager time per report), and practice outcome stats (NPS, referral rate). First-party data, CC BY 4.0 — citable.

estimate

estimate_coaching_cost

Fair market rate for coaching or mentoring in 2026, by coaching type, client role, coach territory, coach seniority, and engagement length. Returns a per-session range, program total, and red flags (too cheap / brand margin). Anchored to ICF Global Coaching Study 2025, Tandem Coach 2026 credential bands, and CEE market survey data. Same logic as the live calculator at marian.coach.

first

get_first_time_manager_guidance

Guidance for the IC→manager transition: the EM responsibility triangle (leadership/processes/delivery — pick two), the six most common first-time-manager failure modes, readiness self-check questions, and what the first months should look like. 52% of Marian's 300+ mentees arrive exactly at this transition.

one

get_one_on_one_playbook

Situation-specific 1:1 scripts and templates from Marian Kamenistak's mentoring practice: first mentoring/direction-setting session, underperformance conversation, promoting a developer to manager, fixing status-update 1:1s, and the 10-question career-move checklist. These are the actual templates used across 3,400+ sessions.

Eng Leadership Toolkit — questions

Answers built from our own checks of this server.

What can Eng Leadership Toolkit do?

It exposes 9 tools, read directly from the server on our last check. Among them: assess_team_lead_readiness, build_mentoring_business_case, calculate_developer_value, calculate_engineering_manager_value, choose_mentor_coach_or_advisor, estimate_coaching_cost and 3 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Eng Leadership Toolkit working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 988 ms. The bar chart above shows every period we have measured.

Is Eng Leadership Toolkit still maintained?

The linked repository no longer exists on GitHub — it was deleted or made private. We show this because it changes what you can expect: an unmaintained server may keep answering for months and then stop without warning.

How do I connect Eng Leadership Toolkit?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Eng Leadership Toolkit need an API key?

No. Eng Leadership Toolkit completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 9 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Eng Leadership Toolkit?

It answers our handshake in 988 ms on average, which is faster than 5% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
