Available components
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. How we score →
Endpoint Security63
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 4 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability47
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 1402 tokens (~350/item across 4 items; 4 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management27
- Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

excel_inspect ~140
查看 Excel 结构：各 sheet 的列名/类型/行数 + 前 N 行预览。免费(0 credit)。 出图前先调它看清有哪些 sheet、列、哪些列是数值，再据此选 chart_type 与 x/y。

| group_by | — | — | 分组维度列。给了就进聚合模式：按这些列分组，对 measures 求 agg |
| limit | — | — | 最多返回多少行（取前 N / Top-N）；硬上限 1000 |
| measures | — | — | 聚合模式：要统计的数值列；缺省=所有数值列 |
| sheet | — | — | 目标工作表名；缺省第一个 sheet。先用 excel_inspect 看列名 |
