get_startedread-only

Call this for a greeting (hi, hello), a connectivity/liveness test, 'what can you do', or any message too general to match a specific tool below. Returns the full menu of real questions this server answers, each mapped to the tool name that answers it, so the next call can go straight to the right tool.

get_more_toolsread-only

Check for additional tools whenever your task might benefit from specialized capabilities, even if existing tools could work as a fallback. Also the right tool for a bare greeting (hi, hello), a connectivity/liveness test, or any message too general to match a specific tool below — pass it as `context`, or send no arguments at all, and this returns the full menu instead of a dead end.

calculate_developer_valueread-only

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_valueread-only

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. Uns

assess_team_lead_readinessread-only

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

get_engineering_leadership_benchmarksread-only

Real benchmarks from 3,662 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.

choose_mentor_coach_or_advisorread-only

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 3,662 mentoring sessions.

get_one_on_one_playbookread-only

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 3,662 sessions.

get_first_time_manager_guidanceread-only

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.

estimate_coaching_costread-only

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.

build_mentoring_business_caseread-only

Build the case that gets your company to pay for leadership mentoring — everything on marian.coach/get-your-company-to-pay-for-mentoring/, personalised: the four-line value formula and the count-then-halve CFO rule, three worked examples (EM, Director, Staff Engineer), napkin math (senior people at risk x replacement cost vs the 1,975 EUR quarter (6 sessions, 5 paid + 1 free) or a 395 EUR pilot
