Strac MCP DLP MCP server

Strac MCP DLP — PII/PHI/PCI & secret redaction for AI agents (MCP)

An open-source Model Context Protocol server that gives any AI agent — Claude, Cursor, VS Code, your own — a way to find and strip sensitive data before it reaches the model.

Point your agent at it, and redact_text turns

...along with a structured list of what was found. It works the same on images, PDFs and scanned documents.

This is a thin client over the Strac DLP API. Bring your own API key; all detection and redaction happens server-side at Strac.

Why

Agents are now wired into inboxes, ticketing systems, CRMs, databases and file stores. Every MCP tool call is a chance for an SSN, a card number, a patient record or an AWS key to be pulled into a prompt — and from there into a model provider's logs, a vector store, a Slack summary or a support ticket.

Filtering that data after the model has seen it is too late. This server puts the check in front of the model: detect first, redact, then let the agent reason over text that no longer carries the sensitive values.

This server is one door into Strac

Redacting a string you hand it is the smallest thing Strac does. The product is coverage: connect Strac to the SaaS and cloud apps where your sensitive data already lives, and it discovers, classifies, redacts and remediates it there — continuously, under your policies, with an audit trail — rather than waiting for someone to paste it into a prompt.

Slack, Google Workspace, Microsoft 365, Salesforce, Zendesk, Box, Dropbox, Jira, Confluence, GitHub, Notion, OneDrive, SharePoint, Snowflake, Databricks, BigQuery, Postgres, MongoDB, AWS, Azure, GCP, browsers and endpoints — 60+ integrations, agentless, no code to write.

That matters most when those systems are reached over MCP. When an agent — Claude Code, Claude Desktop, Cursor, GitHub Copilot, OpenAI Codex — pulls a Salesforce record or a Drive file through an MCP connector, Strac redacts the sensitive data inline, before the agent receives it. That is the difference between asking an agent to redact and enforcing it whether or not it asks.

strac.io/mcp-integrations is that product. This repo is its developer-facing sliver: the same detection engine, reachable from any MCP client, for when you want to sanitise a string or a file yourself.

Every MCP invocation your agents make — tools called, files read, the identity behind the prompt — captured and inspected.

60-second quickstart

1. Install

pip install strac-mcp-dlp

2. Request an API key

Request a key, or email hello@strac.io.

Keys are prefixed sklive (production) or sktest (sandbox); the server picks the matching endpoint automatically.

3. Add it to your MCP client

Claude Desktop — ~/Library/Application Support/Claude/claudedesktopconfig.json on macOS, %APPDATA%\Claude\claudedesktopconfig.json on Windows:

{
  "mcpServers": {
    "strac-dlp": {
      "command": "strac-mcp-dlp",
      "env": {
        "STRAC_API_KEY": "sk_live_your_key_here"
      }
    }
  }
}

Claude Code:

claude mcp add strac-dlp --env STRAC_API_KEY=sk_live_your_key_here -- strac-mcp-dlp
