MCP server for ClassiFinder — secret scanning tools for AI agents

ClassiFinder MCP Server

An MCP server that gives AI agents the ability to scan text for leaked secrets and redact them before they reach an LLM.

Installation

pip install classifinder-mcp

Setup

Get a free API key at classifinder.ai, then add to your agent config:

Claude Code

{
  "mcpServers": {
    "classifinder": {
      "command": "classifinder-mcp",
      "env": {
        "CLASSIFINDER_API_KEY": "ss_live_your_key_here"
      }
    }
  }
}

Cursor

Add to .cursor/mcp.json in your project:

{
  "mcpServers": {
    "classifinder": {
      "command": "classifinder-mcp",
      "env": {
        "CLASSIFINDER_API_KEY": "ss_live_your_key_here"
      }
    }
  }
}

Tools

classifinder_scan

Scan text for leaked secrets and credentials. Returns findings with type, severity, confidence, and remediation guidance.

Agent: "Check this config for secrets"
→ classifinder_scan(text="AWS_ACCESS_KEY_ID=AKIAJGKJHSKLDJFH3284")
→ Found 1 secret: aws_access_key (critical, confidence 0.95)

classifinder_redact

Replace all detected secrets with safe placeholders. Returns clean text safe to forward to any LLM.

Agent: "Clean this before sending to the model"
→ classifinder_redact(text="key=sk_live_EXAMPLE_KEY_HERE")
→ "key=[STRIPE_LIVE_SECRET_KEY_REDACTED]"

What It Detects

106 secret types including AWS keys, Stripe keys, GitHub tokens, OpenAI/Anthropic/Cohere API keys, database connection strings, private keys, credit card numbers, and more.

ClassiFinder is a detection aid, not a guarantee. No scanner catches 100% of secrets in 100% of formats. See our Terms of Service for full details.
