detect_secretsDetect hardcoded secrets \u2014 API keys, passwords, tokens and private keys \u2014 in source or configuration text. Reports each finding by type, confidence, key name and 1-based position. Values are never returned: previews are truncated and length-annotated, and the surrounding context line has the secret masked out, so a finding can be located without the credential leaving the machine it was

What it does
Open a workspace, press Ctrl+Alt+S (Cmd+Alt+S on Mac), and every detected secret lands in a results document — grouped by file, with line/column positions pointing at the value itself. Run Secrets-LE: Sanitize Secrets to replace the secrets in the active file with a placeholder. Works in VS Code and in VS Code–based editors like Cursor and VSCodium (installable from Open VSX).
Detection is regex-based over the full text of each file, so it works on any text format — code, configs, .env files, YAML, JSON, logs. It is a pre-commit safety net, not a guarantee: a scanner built on patterns can miss secrets and can flag non-secrets. Review the results.
Install
Use it from an AI agent
The same engine runs as an MCP server, so an agent can call it directly instead of you running a command.
Shortened. The full README is on GitHub.
Nothing above is checked by us. What we check is on the safety report.
Install directly
Runs npx -y secrets-le-mcp on your machine. Read the scan report first; the gateway never runs local packages.
