The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.

chartimg_tools_disabledCHART-IMG tools are disabled until CHART_IMG_API_KEY is set (see https://doc.chart-img.com/#introduction).
chartimg_v1_mini_chart_storageCHART-IMG v1: save a TradingView **mini** chart to public storage; returns JSON with `url` (see GET /v1/tradingview/mini-chart/storage).
chartimg_v1_advanced_chart_storageCHART-IMG v1: save an **advanced** chart to public storage; returns JSON with `url` (GET /v1/tradingview/advanced-chart/storage).
chartimg_snapshot**Preferred for agents:** one-call TradingView snapshot (v2 advanced → storage). Supply a full `symbol` (e.g. BINANCE:BTCUSDT.P for Binance perp). Defaults: interval 5m, dark theme, candles, Volume on, size = max allowed (800×600 unless CHART_IMG_MAX_* set). Width/height are clamped automatically.
chartimg_v2_advanced_chart_storageCHART-IMG v2: POST advanced chart to **storage**; returns JSON with hosted image URL (POST /v2/tradingview/advanced-chart/storage). Prefer `chartimg_snapshot` for common cases. Width/height in `body` are auto-clamped.
chartimg_v2_advanced_chart_imageCHART-IMG v2: POST advanced chart and return **base64** image data (POST /v2/tradingview/advanced-chart). Responses can be large; prefer storage tools. Width/height in `body` are auto-clamped.
chartimg_v2_layout_chart_storageCHART-IMG v2: render a **shared** TradingView layout to storage (POST /v2/tradingview/layout-chart/storage/{layoutId}). Layout must be shared unless session cookies are provided. Width/height in `body` are auto-clamped.
chartimg_v2_layout_chart_imageCHART-IMG v2: POST shared layout chart image as **base64** (POST /v2/tradingview/layout-chart/{layoutId}). Prefer storage variant. Width/height in `body` are auto-clamped.
chartimg_v3_exchange_listCHART-IMG v3: list TradingView exchange ids (GET /v3/tradingview/exchange/list).
chartimg_v3_exchange_symbolsCHART-IMG v3: symbols for an exchange (GET /v3/tradingview/exchange/{exchangeId}). **Note:** `payload` may be empty (plan or API); do not rely on it to discover symbols — use TradingView / CHART-IMG docs (e.g. BINANCE:BTCUSDT.P for Binance USDT perpetual).

CHART_IMG_API_KEYSet in .env (from chart-img.com)CHART_IMG_MAX_HEIGHTCHART_IMG_MAX_WIDTHTool annotations
No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
10/10 tools missing one or more hints — chartimg_tools_disabled (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); chartimg_v1_mini_chart_storage (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); chartimg_v1_advanced_chart_storage (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +7 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Tool inputs are validated
Only 0/10 tool handlers declare input schemas (0%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
Only 0/10 tool handlers wrap calls in try/catch (0%)
Wrap each tool handler body in try/catch and return a structured error response.
License file
No license file
Add a LICENSE file (MIT, Apache-2.0, etc.).
Tests exist
No test files found
Add tests that exercise each declared tool.
Production dependencies are patched
0 critical, 14 high severity in production deps — axios@1.7.9 (high), axios@1.7.9 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
