Overview

AI-generated overview

Sheetspec is a local MCP server that provides contract testing and quality gates for spreadsheets created by AI agents.

What you can do
Checks spreadsheets produced by AI agents against defined contracts and quality gates, so generated workbooks can be validated before use. The manifest lists no tools, so the exact operations are not documented here. It runs as a local process on the user's machine and is intended for desktop use only.
When to use it
Useful when an assistant generates or edits spreadsheets and you want an automated check that the output meets agreed structure or quality rules before relying on it.
Requirements
Runs locally over stdio as a Python package (sheetspec) launched with uvx, so a Python environment with uvx available is needed. Desktop only; no web execution. No authentication, environment variables or headers are declared.
Before you install
The manifest lists no tools, so what it reads, writes or changes is not documented; review before pointing it at important workbooks. No credentials or network access are declared.

Installation

In SourceWeft

  1. Open Sheetspec in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

25% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 days25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
