Secrets-LE

Find hardcoded credentials in a codebase, and never print one into the report

FreeOpen sourceMITNo network access

No editor in the loop? npx -y secrets-le-mcp runs the same engine as an MCP server, so an agent can call detect_secrets with nothing else installed, and cargo install secrets-le puts the same check in a terminal. Every way to install it.

Secrets-LE in use: Find hardcoded credentials in a codebase, and never print one into the report

What Secrets-LE does

The cheapest place to catch a committed credential is before the commit. Secrets-LE scans your workspace for API keys, passwords, tokens and private keys, groups the findings by file with positions pointing at the value, and can replace them in place with a placeholder. Detection is regex-based over full text, so it works on code, configs, .env files, YAML, JSON and logs alike.

What people use it for

Pre-commit safety net

Scan the workspace and see every detected credential grouped by file, with line and column positions.

Sanitize in place

Replace the secrets in the active file with a placeholder, ready to share or paste into an issue.

Patterns, not proof

A scanner built on patterns can miss secrets and can flag things that are not. Review the results — it is a net, not a guarantee.

4 commands in the palette

Open the command palette and type the name. Nothing is bound to a shortcut by default — the editor's keymap is the user's, not ours.

Install Secrets-LE

VS Code

ext install nolindnaidoo.secrets-le

Open Quick Open (Cmd/Ctrl+P) and paste.

Cursor / VSCodium

cursor --install-extension OffensiveEdge.secrets-le

VS Code forks pull from Open VSX, where the namespace is OffensiveEdge.

Zed

npx -y secrets-le-mcp

Works in Zed today — add the command above as a custom MCP server from the agent panel, and detect_secrets appears in its tool list. There is no one-click listing in Zed's extension registry yet.

AI agents

npx -y secrets-le-mcp

Runs Secrets-LE's engine as an MCP server, so an agent can call detect_secrets with no editor involved. VS Code 1.101+ needs nothing — the extension registers it for you.

Where it ships

One engine, 6 places to get it. The ids differ by registry — copy the one for the editor you use.

Where Secrets-LE lives

The other 15

Extract every string in a codebase, with its position, so a person can read them

Extract every hardcoded number in a codebase, so a person can check them

Extract every file path in a codebase, and say whether it still points at anything

Extract every color in a codebase, and say which ones are not in your palette

Extract every URL in a codebase, with its protocol and exact position

Extract every date and timestamp, and the exact instant each one resolves to

Extract every quantity with its unit, normalized, and refuse the ambiguous ones by name

Extract every UUID, ULID, NanoID, ObjectId and Snowflake, and decode the time inside

Extract every IP address, CIDR block and MAC, normalized and classified by scope

Find every regex in a codebase, and report which can be driven into catastrophic backtracking

Check whether a page is scrapeable before the scraper is written, and say when it cannot tell

Find where one dependency is constrained differently across a repository's manifests

Identify the i18n library a project uses, then audit its catalogs by that library's rules

Compare the dotenv files in a tree, and say which keys are missing from which

Find the Unicode that hides meaning — bidi controls, invisibles, homoglyphs, mixed scripts
