# Bynn

Bynn connects a coding agent to tools for checking whether PDFs and images are forged, altered, or AI-generated. Use it to bring document analysis into a project.

## What it does

The MCP server connects an agent to Bynn tools at `https://mcp.bynn.com`. Those tools support integration of PDF and image checks for forgery, tampering, and AI-generated content. Bynn also offers identity verification and content detection.

In Claude Code, the plugin registers the server, but you still need to sign in through `/mcp` before its tools work. For headless use, pass a `BYNN_API_TOKEN` instead. Use the endpoint root: adding `/mcp` to the URL returns a 404.

Keep the original file intact. Resizing, re-encoding, or stripping metadata can remove the traces the detectors inspect. Browser SDK results also need server-side confirmation.

## Requirements
- Remote server: `https://mcp.bynn.com`
