Who it is for
Finance teams that need an audit trail separating human edits from agent edits.
Rockhopper
Spreadsheet change attribution and approvals for Excel and Sheets
Overview
What Rockhopper does
Rockhopper sits beside Excel and Google Sheets files rather than inside them, recording who changed what and whether the change came from a person or an agent. The connector brings that record into conversation for files already enrolled in a Rockhopper workspace.
The listing describes attribution and history first: which version carried AI edits, cell-level and metric-level change history across versions, and uncommitted changes sitting in a file without an author. Around that sit version management, review and approval requests tied to a specific version, and comment threads that can be read, answered, and resolved. Files can be searched by name, comment text, or version note, and renamed. Cell data and formulas are explicitly out of scope: the connector governs changes rather than making them.
Tool surface
Sixteen tools are claimed for a governance layer that never touches cell values, and none are named without credentials; the endpoint answers 401.
Availability
Where Rockhopper is listed
Rockhopper is listed in the Claude connectors directory only. Rockhopper Inc. has no app under the same domain in the ChatGPT directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.
The MCP server behind a Claude connector is usually the same server a ChatGPT app would need, so the absence is a distribution decision rather than a technical one.
Claude listing
In the Claude connectors directory
Rockhopper publishes 16 tools to Claude, deeper than 61.6% of the 1,253 Claude-listed connectors.
The median Claude-listed connector filed under Productivity publishes 12, so this one runs 4 tools above its bucket's median and ranks 186th of 462 by tool count.
It falls in the 11-20 tools band, which holds 22.5% of the Claude directory.
Rockhopper publishes a remote MCP endpoint. Claude connects to it over HTTP; there is nothing to install locally.
Every connector in the Claude directory is remote, all 1,253 of them, so transport is not a differentiator there.

Rockhopper is community-listed in the Claude directory, the tier 770 of 1,253 connectors sit in (61.5%). It is the default for a self-published server, and says nothing either way about quality.
In the publisher's words
How Rockhopper Inc. describes it
Rockhopper - spreadsheet audit, approvals, and AI-agent governance for Excel & Google Sheets Rockhopper tracks exactly who - human or AI agent - changed what in a spreadsheet, and adds review/approval workflows on top. Use it for: Attribution & history - see which version of a file had AI-made edits vs. human edits; pull cell-level or metric-level change history across versions; surface uncommitted ("unattributed") changes currently sitting in a file. Versions - list version history for a file, or commit current changes as a new version. Reviews & approvals - create, approve, or cancel a review request for a specific version, so changes go through sign-off before they're final. Comments - read, add, reply to, and resolve comments and discussion threads on a file, including the latest conversation tied to a specific file. File management - search enrolled files by name, comment text, or version notes; rename a file. Trigger this when the user asks who changed a spreadsheet, whether an edit was made by AI or a person, wants to compare periods/versions, needs to approve or request approval for a file, wants to see comments or discussion on a spreadsheet, or names Rockhopper directly. Only works on files already enrolled in the user's Rockhopper workspace (Microsoft Excel or Google Sheets) - it doesn't edit cell data or formulas directly.
