## Trust

- hygiene: 80
- liveness: 100
- freshness: 100

- drivers: +dns-namespace +website +reachable +uptime-100% +updated-0d-ago -no-repository
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 71/100 (needs work)

### protocol: n/a (weight 25)

- n/a `protocol.modern`, `protocol.stateless`, `protocol.transport`, `protocol.list_ttl`: no remote answered a protocol handshake (not probed yet, unreachable, or local-only)

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 71 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- fail `tools.annotations`: no tool declares readOnlyHint or destructiveHint, so clients cannot tell safe calls from risky ones
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: mg_calculator_cagr (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); mg_calculator_cagr_update (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); mg_calculator_cagr_sync (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 4,868 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: n/a (weight 15)

- n/a `stability.changes`, `stability.rug_pull`: tool history not recorded yet

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 17, about 4,868 tokens to load them all
- badge: [![protogrid quality](https://protogrid.dev/badge/app.marketgenius/mcp.svg)](https://protogrid.dev/servers/app.marketgenius/mcp)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (17)

- `mg_calculator_cagr`: 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.
- `mg_calculator_cagr_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.
- `mg_calculator_cagr_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.
- `mg_calculator_cagr_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).
- `mg_calculator_dividend`: Open the Dividend 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 → ask "By amount invested or by number of shares?", then collect only the
  input schema fields matching that mode — do not guess or invent field names.
- `mg_calculator_dividend_state`: Read the current field values of the open Dividend 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.
- `mg_calculator_dividend_sync`: Sync user-entered field values of the open Dividend 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.
- `mg_calculator_dividend_update`: Update one or more fields in the already-open Dividend Calculator.
ALWAYS call mg_calculator_dividend_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).
- `mg_calculator_market_cap`: Open the Market Cap 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 → ask "Would you like to pre-fill share price and shares outstanding?", then collect only the
  input schema fields matching that mode — do not guess or invent field names.
- `mg_calculator_market_cap_state`: Read the current field values of the open Market Cap 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.
- `mg_calculator_market_cap_sync`: Sync user-entered field values of the open Market Cap Calculator back

- `mg_calculator_profit_margin`: Open the Profit Margin 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 → ask "Would you like to pre-fill revenue and cost?", then collect only the
  input schema fields matching that mode — do not guess or invent field names.
- `mg_calculator_profit_margin_state`: Read the current field values of the open Profit Margin 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.

- `mg_list`: 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.
