Sigstore

What is Sigstore?

Sigstore is an MCP server that automatically detects Base64 encoded content in text, decodes it, and replaces it back into the original text. Non‑Base64 portions are preserved unchanged. It is designed for developers or LLMs that need to handle Base64 encoded strings in conversations or configuration processing.

How to use Sigstore?

Install the server with pip install -e . and configure your MCP client with the command python3 -m mcp_content_integrity.server in the server’s JSON block. Two tools are available: detect_base64 to scan text and report Base64 segment locations and previews, and decode_base64 to scan, decode, and return the fully processed text.
