Redacta MCP

Pseudonymise medical and clinical documents before they're processed by AI or shared. Redacta replaces patient identifiers with labelled tokens - [PATIENT_NAME_1], [NHS_NUMBER_1], [DATE_OF_BIRTH_1], … - while leaving the clinical meaning intact, and returns a redaction report alongside the cleaned text. It runs locally over stdio via the published package.

People who work with agent skill, anonymization and healthcare and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

01 · Install Redacta MCP

Claude Code

claude mcp add nickjlamb-redacta -- npx -y redacta-mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "nickjlamb-redacta": {
      "command": "npx",
      "args": [
        "-y",
        "redacta-mcp"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key
