PII Shield

Masks names, emails, phone numbers and card numbers before text goes to the model, then restores them after.

Connects to the PII Shield API to detect and replace personal data in text and uploaded files such as PDFs, Word and Excel documents. Muse can redact emails, phone numbers, cards, SSNs, IBANs and custom terms into stable tokens, preview what would be masked, and adjust which detectors a workspace uses.

Try asking Muse: "Redact the personal details from this customer email before I ask Muse to summarize it."

New to Muse?Muse is Meta's AI assistant. PII Shield is an app you add to it, and once it is on, you can ask Muse to do this for you: masks names, emails, phone numbers and card numbers before text goes to the model, then restores them after. It takes about two minutes and you can turn it off any time.

Is it safe to connect?

What Muse can see: You sign in to your own account with it, so Muse can reach what that account allows. Read what it asks for before you agree.

Before it acts: Read what Muse plans to do before you approve it, and remove the app from Muse when you stop using it.

How to add it to Muse

Not in Muse's Connectors list yet, but Muse can still use it. Copy the request below and paste it into Muse. Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust. We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer.

Also use it in ChatGPT or Claude

PII Shield is a remote MCP server, so any assistant that can add a custom connector by link can use it. Same link, same tools.

Add it to ChatGPT
  1. 1

    Open ChatGPT settings

    In ChatGPT, open Settings, then Connectors (called Apps & Connectors on some accounts).

  2. 2

    Turn on developer mode

    Under Advanced settings, switch on Developer mode. That is what lets you add a connector by link.

  3. 3

    Create the connector

    Choose Create, give it a name, paste the link as the MCP server URL, and save. If it needs a sign-in, ChatGPT asks for it here.

  4. 4

    Use it in a chat

    Start a chat, open the tools menu, pick the connector, and ask. ChatGPT asks before it runs a tool the first time.

Custom connectors need a paid ChatGPT plan, and on Team, Enterprise and Edu accounts only an admin can add them. Our "Working" label means the server answered us; it cannot tell whether your plan lets you add it. All connectors that work in ChatGPT

Add it to Claude
  1. 1

    Open Claude settings

    In Claude, open Settings, then Connectors.

  2. 2

    Add a custom connector

    Choose Add custom connector, give it a name, and paste the link.

  3. 3

    Connect and use it

    If it needs a sign-in, Claude sends you to it. Then turn the connector on in a chat from the tools menu and ask.

Custom connectors are available on paid Claude plans; on Team and Enterprise accounts an admin may need to add them. Our "Working" label means the server answered us; it cannot tell whether your plan lets you add it. All connectors that work in Claude

Tools · 6

redactRedact personal data (email, phone, cards, SA ID, SSN, IP, IBAN, names, custom terms) from text, replacing each value with a stable token like [EMAIL_1]. Call this before putting sensitive text into a prompt or context. NOTE: detection is automated and is not a guarantee; it can
detect_piiReport what personal data appears in text (counts by type) without returning the raw values. Use to check whether text is safe to share. NOTE: detection is automated and is not a guarantee; a clean result does not prove the text is free of personal data.
redact_documentRedact PII from an uploaded file or document before sharing it with an AI. Works on PDFs, Word (.docx), Excel (.xlsx), and text-based files (txt, csv, json, code, transcripts, logs). Pass base64 file data with media_type/filename, OR raw text. Returns the redacted text and counts
list_detectorsList the PII types this shield can mask, and confirm custom regex/terms are supported. Call this to see what coverage is available.
get_coverageShow your workspace's current PII coverage (which detectors are on, custom terms, custom patterns). Uses the workspace key from your MCP server URL.
set_coverageChange what this workspace masks, right from your chat. Turn detectors on/off (e.g. enable PERSON name masking), add always-mask terms, or add custom PII as regex (e.g. employee IDs 'EMP-\\d{5}'). Uses the workspace key from your MCP server URL.
