What this server can do

9 functions, named and described by the server itself. Parameter names are shown because they say more about what a function does than its name usually does.

assess_team_lead_readiness(answers)
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_mentoring_business_case(role, problem, team_size, avg_salary_eur, at_risk_attrition, delayed_revenue_eur)
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. Required: role.
calculate_developer_value(level, scores)
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. Required: level.
calculate_engineering_manager_value(level, track, scores)
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. Required: level.
choose_mentor_coach_or_advisor(situation)
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.
estimate_coaching_cost(scope, territory, client_role, coaching_type, coach_seniority)
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. Required: coaching_type, client_role, territory, coach_seniority.
get_engineering_leadership_benchmarks(topic)
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.
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.
get_one_on_one_playbook(situation)
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. Required: situation.

Signals

These are separate measurements of different things. They are deliberately not combined into one score, because a popularity number that mixes website traffic with saves and stars cannot be checked or acted on.

These share tags the maintainers applied themselves, such as cloudflare-workers, engineering-leadership, engineering-management. Common tags like "mcp" or "ai" are ignored for this: agreeing with six hundred other projects is not a similarity.

This is not a recommendation and not a test result. It is a map of what the authors said their work is about.
