Overview

AI-generated overview

A local MCP bundle that anonymizes tabular and JSON records with deterministic, reversible HMAC-based masking for de-identification.

What you can do
  • Anonymize tabular and JSON records by masking identifying fields.
  • Produce deterministic masked values via HMAC so the same input maps to the same token.
  • Reverse the masking to restore original values when needed.
  • Act as a de-identification guard over structured data before it is shared or processed.
  • No individual tools are listed in the manifest, so exact operations are not documented.
When to use it
Use it when an assistant needs to work with spreadsheets or JSON records containing personal or sensitive fields and you want consistent pseudonyms rather than raw values, while keeping the option to restore the originals.
Requirements
Runs as a local process on the desktop via an MCP bundle package; no authentication, environment variables or headers are declared. A secret key for the HMAC masking is implied by the description but its configuration is not documented.
Before you install
Masking is described as reversible, so anyone holding the key or the reversal capability can recover the original data; treat the key as a secret. The manifest declares no credentials or configuration, so how the HMAC key is supplied is unclear. No tool list or README is available to confirm exactly what data is read or written.

Installation

In SourceWeft

  1. Open GenPark Structured Data Mask Reconstruction Guard 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.

Score

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.

  • Tools listed15 pts

    Answer tools/list without a credential, or ship a package that starts in a sandbox without one.
