Prompt Cleaner

Sanitizes and redacts sensitive information from user prompts using OpenAI-compatible APIs to intelligently clean text while detecting and removing API keys, tokens, emails, and other secrets before processing.

Prompt Cleaner MCP server by David Colon that provides AI assistants with tools to sanitize, redact, and professionally reformat user prompts before they're processed by language models. The implementation integrates with local OpenAI-compatible APIs to intelligently clean prompts while automatically detecting and redacting sensitive information like API keys, tokens, emails, and other secrets using pattern matching. Features comprehensive retry logic with exponential backoff, structured JSON output with notes and risk assessments, configurable temperature settings, and multiple tool aliases (cleaner, sanitize-text, normalize-prompt) for different use cases, making it valuable for developers who want to ensure prompt hygiene and prevent accidental exposure of sensitive data in AI workflows.
