SecureInput: open-source local secret input for MCP coding agents

rishabhgusain · reddit · 2026-11-03

An MIT-licensed MCP server (macOS/Linux, Node.js 22+) that lets coding agents receive API keys safely: input via inline MCP App or a paired localhost browser, delivery via stdin, env var or .env file, with the MCP result reporting status only. The author spells out the trust boundaries — host/command must be trusted, filesystem-capable agents may read .env, inline mode skips browser command review — and ships a security-model doc.
