## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-08-03.

- **Endpoint Security**: 74/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 67/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 1537 tokens (~170/item across 9 items; 9 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 27/100
  - Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### `calculate_developer_value` (~202 tokens)

Developer value & salary calculator

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.

Input parameters:

- `level` (string, required): The developer's current (or claimed) level — sets pillar weights and baseline
- `scores` (object): Optional 0-10 score per skill. Valid keys: discipline-mastery, code-quality, debugging, system-design, tech-decisions, data-performance, shipping-outcomes, production-ownership, domain-expertise, com…

Output parameters:

- `level` (string): Seniority level the score maps to, when the tool computes one.

Team lead readiness test — should this engineer become a team lead?

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.

Input parameters:

- `answers` (object): Answers keyed by question id (q1-q17), each the 0-based index of the chosen option for that question (NOT a rating — option scores are calibrated and non-monotonic). Omit to receive the 17 questions…
