theluckystrike Spreadsheet MCP

The Spreadsheet MCP server allows agents to read, filter, group, sum, sort, and query Excel (.xlsx) and CSV files without corrupting them. It supports adding computed columns, converting between XLSX, CSV, TSV, and JSON formats, and performing statistical analysis like min/max/avg on large datasets.

Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Reading, analysing and writing spreadsheet data in XLSX, CSV, TSV and JSON. It covers sheet and column overviews, reading rows, filtering, grouping and aggregating, column statistics, searching cells, computed columns, writing rows and converting between formats. McpStamp's hosted service has no file system, so data arrives as CSV text, a base64 XLSX upload or a public URL, is kept per user account up to 2 MB, and written files come back as download links valid for one hour. The free tier writes up to 500 rows per file. One lifetime key unlocks this server and all 58 others: https://mcp.zovo.one/buy/bundle?src=instr.spreadsheet

license_status — License status
Advertised by the server during the last successful anonymous check.
Advertised read-only

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.

Advertised by the server during the last successful anonymous check.

sheet_load — Load a sheet into this session
Advertised by the server during the last successful anonymous check.
Advertised destructive

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.

    "spreadsheet-mcp-zovo": {
      "type": "streamableHttp",

      "url": "https://mcp.zovo.one/mcp/spreadsheet"
