MCP Presidio Server (Anonymize/Deanonymize)

This project exposes the same functionality via MCP tools and FastAPI endpoints.

Quickstart

python -m venv .venv && source .venv/bin/activate  # on Windows: .venv\Scripts\activate
pip install -r requirements.txt
uvicorn app.main:app --reload

Endpoints

• POST /session -> { "session_id": "<uuid>" }

• POST /anonymize body:

{
  "session_id": "uuid",
  "messages": [{"content": "Secret is 123, password=foo"}]
}

returns anonymized messages and stores mapping for the session.

• POST /deanonymize body:

{
  "session_id": "uuid",
  "text": "<<CUSTOM_TOKEN_0>> is 123, <<pass_pattern_...>>"
}

MCP server

Run the stdio MCP server:

python mcp_server/server.py

Register it in your MCP-compatible client pointing to this command.

Notes

• Storage uses SQLite at app/data.db with tables sessions and mappings.

• Custom patterns mirror the code you provided; add more Presidio recognizers as needed.

• Placeholders look like <<ENTITY_#>> and are reversible per session_id.
