Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 43 ms.

  • Pass
    Valid handshake

    protocolVersion 2025-11-25, serverInfo.name mcp-spreadsheet.

  • Pass
    Lists tools

    tools/list returned 13 tools.

  • Pass
    Current protocol

    Negotiated 2025-11-25. The bar is 2025-06-18 or newer.

  • Pass
    HTTPS

    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 43 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 43 ms over 1 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured
    Reliable (uptime)

    1 of 1 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

  • Not measured
    Free tier cited

    No publisher quote has been checked.

Tools

  • Pass
    Tools described

    Every tool description is at least 20 characters.

  • Pass
    Valid input schemas

    Every inputSchema is a JSON Schema object.

  • Pass
    Parameters documented

    38 of 46 parameters have a description (83%). The bar is 80%.

  • Pass
    Safety hints

    Every tool sets readOnlyHint or destructiveHint.

Publisher

  • Pass
    Verified namespace

    Listed in the Official MCP Registry.

  • Not measured
    Website matches publisher

    This namespace is not a reverse domain, so the website comparison does not apply.

  • Pass
    Source repo linked

    A repository URL is on file.

  • Pass
    Repo owner matches

    The GitHub repository owner matches the namespace login.

  • Pass
    Recently updated

Capabilities

Tools 13

license_activate

Turn Pro on for this connection with key, an MCPL1.<payload>.<signature> issued at checkout for this server or the bundle. Data under your token stays; a wrong or expired key changes nothing. license_status confirms it.

Discovered
license_status

Report this endpoint's licence state for your token as JSON: the product, the tier free or pro, why it is not Pro, and the checkout URL. Call it to explain a free-tier refusal. No arguments, nothing changes.

Discovered
sheet_add_column

Call this tool to add a computed column and save the result to a NEW file; the source is never modified unless out_path points at it. Returns the new file path, the row count and a preview of the first rows.

Discovered
sheet_convert

Call this tool to convert a sheet between excel (xlsx), csv and json. Writes a new file next to the source unless out_path is given; the source is never modified. Returns the new file path with its row and column counts.

Discovered
sheet_files

List the sheets loaded for this token, with their sizes and the storage left under the 2 MB cap.

Discovered
sheet_find

Call this tool to search every cell of a spreadsheet or CSV for text; built-in file readers cannot parse spreadsheets. Matching is case insensitive. Returns cell addresses with a preview of the row each hit is on.

Discovered
sheet_info

Call this tool for any spreadsheet or CSV file path; built-in file readers cannot parse spreadsheets and must not be used for them. Start here: sheet names, size, header row, column types and samples.

Discovered
sheet_load

Upload data to work on. This hosted endpoint has no filesystem, so instead of a file path you send the data once with sheet_load and then pass its name as `path` to sheet_info, sheet_read, sheet_query, sheet_stats, sheet_find, sheet_add_column, sheet_convert and sheet_write. Give exactly one of csv (raw text, comma or tab separated), xlsx_base64 (a base64-encoded .xlsx workbook) or url. url: fetch a public file instead of pasting base64 (recommended above about 10 KB): the url is fetched here with a 10 second timeout, at most 3 redirects, public http(s) hosts only, and a 2 MB cap, and a fetched file is stored as an .xlsx when it carries the PK zip header and as delimited text otherwise. Loaded sheets are kept for your token and survive between calls; the total is capped at 2 MB per token. Files the other tools write come back as a download link that is valid for one hour.

Discovered
sheet_query

Call this tool for any spreadsheet or CSV file path; built-in file readers cannot parse spreadsheets and must not be used for them. Filter, group, aggregate and sort in one call; never hand sums over sheet_read rows.

Discovered
sheet_read

Call this tool for any spreadsheet or CSV file path; built-in file readers cannot parse spreadsheets and must not be used for them. Reads rows as a table, JSON or CSV; page with limit/offset or an A1 range.

Discovered
sheet_stats

Call this tool for any spreadsheet or CSV file path; built-in file readers cannot parse spreadsheets and must not be used for them. Whole-column statistics: count, empty, distinct, min, max, sum, mean, median.

Discovered
sheet_unload

Delete one sheet loaded for this token, freeing its space under the 2 MB cap.

Discovered
sheet_write

Call this tool to write rows to an xlsx, csv, tsv or json file; the extension of out_path picks the format. mode is new_file, append or overwrite. Other sheets are kept. Free: 500 rows per file.
