## 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 2026-08-04.

- **Endpoint Security**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 17 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - 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**: 58/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (poor).
  - Context-footprint check failed: tool/resource definitions use about 3275 tokens (~155/item across 21 items; 17 tools + 4 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 30/100
  - Stability observed for 9 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 99/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 96% of tool parameters carry a description.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.
  - Supports UI / widget rendering.

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.

## MCP tools (17)

### `mg_list` (~59 tokens)

List Marketgenius Tools

List all available Marketgenius tools with their names, descriptions, categories, and resource URIs. Use mg_list to discover what's available, or filter by category.

Input parameters:

- `category` (string): Filter by category. Omit to list all tools.

### `mg_calculator_cagr` (~151 tokens)

CAGR Calculator

Open the CAGR Calculator React MCP App UI.
ALWAYS ask first — never call this tool silently:
"Open the calculator directly, or pre-fill it with your inputs?"

IF directly → call this tool now with no params. STOP. Do not ask anything else.
IF pre-fill → collect only the input schema fields — do not guess or invent field names.

Input parameters:

- `beginningValue` (string): Beginning (initial) investment value.
- `currencySymbol` (string): Currency symbol, e.g. "$" or "€". Default: "$"
- `endingValue` (string): Ending (final) investment value.
- `years` (integer): Number of years of investment. Default: 0

### `mg_calculator_cagr_update` (~218 tokens)

CAGR Calculator — Update

Update one or more fields in the already-open CAGR Calculator.
ALWAYS call mg_calculator_cagr_state first — the user may have
changed values manually in the GUI and you must not overwrite them.
Pass the version you received from that call (or from the open tool
if updating immediately after opening). Only pass the fields the
user explicitly asked to change; omit all others. Send all changes
in a single call — multiple sequential calls lose intermediate
updates (only the last one applies).

Input parameters:

- `beginningValue` (string): Beginning (initial) investment value.
- `currencySymbol` (string): Currency symbol, e.g. "$" or "€". Default: "$"
- `endingValue` (string): Ending (final) investment value.
- `sessionId` (string, required): Session ID returned by the open tool.
- `version` (integer, required): Current session version — call mg_calculator_cagr_state first to get this.
- `years` (integer): Number of years of investment. Default: 0

### `mg_calculator_cagr_sync` (~137 tokens)

CAGR Calculator — Sync

Sync user-entered field values of the open CAGR Calculator back
to the session store so the model can read them via the state tool.
Called by the View after any field change; hidden from the model.

Input parameters:

- `beginningValue` (string): Beginning (initial) investment value.
- `currencySymbol` (string): Currency symbol, e.g. "$" or "€". Default: "$"
- `endingValue` (string): Ending (final) investment value.

### `mg_calculator_cagr_state` (~67 tokens)

CAGR Calculator — State

Read the current field values of the open CAGR Calculator.
Call this before answering any question about the current values —
the user may have changed fields manually in the GUI.
Do not call this on a loop; call it once on demand.

Input parameters:

- `sessionId` (string, required)
