Category Data and Analytics
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 → Why this is hard to score →
Endpoint Security80
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- 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 Usability68
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 1721 tokens (~573/item across 3 items; 2 tools + 1 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 Management3
- Stability observed for 1 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
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 2 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
- Supports UI / widget rendering.Pass
Every change we have recorded for this component, newest first. Security-relevant changes are always shown. ▲ marks a change for the better, ▼ a change for the worse; unmarked changes are neutral.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
compare_spreadsheets Compare spreadsheets ~853
Use this when the user has two versions of the same spreadsheet (CSV or Excel: price list, inventory, roster, budget, product catalog, CRM export) and wants to "compare two excel files", "compare two spreadsheets", "find the differences between two csv files", "what changed between these files" or "list what changed". Matches rows by a key column it detects (or key_columns), lists all added, removed and changed rows with each changed cell old -> new, numeric change and percent, plus renamed/moved columns and key changes, and returns an Excel workbook (Summary, Changed, Cell changes, Added, Removed, annotated new version) and a changes CSV. Does not merge or join two different tables (e.g. customers + orders), does not compare Word or PDF documents, and does not edit either file.
| Name | Type | Req | Description |
|---|---|---|---|
| column_map | object | – | Old column name -> new column name for renamed columns, e.g. {"Unit Price": "Price (USD)"}. Turns off automatic rename detection. |
| compare_numbers_as_values | boolean | – | Compare numbers by value so "1,200.00" equals 1200, e.g. true (default). Codes with leading zeros (00123) stay text. |
| compare_row_numbers | boolean | – | Compare a running row-number column (#, Row, No.: 1, 2, 3...) like any other column, e.g. true. Default false: it shifts whenever a row is inserted, so it is skipped with a note. |
| detect_key_changes | boolean | – | Report a removed row and an added row whose other values are identical as one key change (e.g. a SKU renumbered), e.g. true (default). |
| header_row_new | integer | – | Row number of the column headings in the new file, e.g. 3. |
| header_row_old | integer | – | Row number of the column headings in the old file when it is not detected, e.g. 3 when two title rows come first. |
| ignore_case | boolean | – | Treat ABC and abc as equal, e.g. true. Default false. |
| ignore_columns | array | – | Columns to leave out of the comparison, e.g. ["Last updated", "Notes"]. |
| key_columns | array | – | Column(s) that identify a row, to override the automatic key, e.g. ["SKU"] or ["Store", "Product code"]. |
| new_file | object | – | The NEWER version (CSV, TSV or Excel .xlsx), e.g. pricelist_2026Q4.xlsx or roster-october.csv. |
| new_sheet | string | – | Sheet (tab) to read from the new workbook, e.g. Prices Q4. |
| new_table | string | – | Instead of new_file: the newer version pasted as CSV/TSV text with a header row, e.g. "SKU,Price\nA1,10.50\nC3,7.00". |
| normalize_dates | boolean | – | Compare dates by calendar day, so 2026-03-05, 3/5/2026 and an Excel date serial are equal, e.g. true (default). |
| numeric_tolerance | number | – | Numbers that differ by this much or less count as equal, e.g. 0.01 to ignore rounding by a cent. Default 0. |
| old_file | object | – | The OLDER version (CSV, TSV or Excel .xlsx), e.g. pricelist_2026Q3.xlsx or roster-september.csv. |
| old_sheet | string | – | Sheet (tab) to read from the old workbook, e.g. Prices Q3. Default: the sheet with the same name as in the new workbook, else the first sheet with data. |
| old_table | string | – | Instead of old_file: the older version pasted as CSV/TSV text with a header row, e.g. "SKU,Price\nA1,10.00\nB2,5.00". |
| trim_whitespace | boolean | – | Ignore leading/trailing and repeated spaces, e.g. true (default). |

summarize_changes Summarize changes ~799
Use this when the user has two versions of a spreadsheet and wants a summary rather than a full list: "how many prices went up", "which columns changed the most", "biggest changes between these two files", "average price increase". Returns counts (changed, added, removed rows), per-column statistics (cells changed, increases, decreases, total and average percent change, largest increase and decrease) and the biggest single changes, with the same Excel and CSV downloads. Use compare_spreadsheets for the row-by-row list. Does not forecast or explain why values changed.
