What it can do
The server asks you to sign in before it lists its tools.

Common questions
Is Secrets Leak Audit safe?
It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 38 days ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.
What can I use instead?
In the same category: Penthera, Draugr, Harbor

secrets-leak-audit-mcp
An MCP server that scans text and diffs for accidentally-committed credentials — the single most common "oops" in software, and an easy thing for an AI coding agent to introduce without noticing (pasting a working example that includes a real key, or writing a test fixture with a plausible-looking but real value).
What it catches
High-precision vendor key matches. Real, current (2026) structural formats for AWS access keys, GitHub PATs (classic and fine-grained), Stripe live keys, Slack tokens, Google API keys, OpenAI and Anthropic keys, npm tokens, SendGrid, Twilio, PEM private key blocks, JWTs, and database connection strings with embedded credentials. These are precise format matches, not guesses — an AWS key is AKIA/ASIA + 16 specific characters, not "looks like it might be a key."
Entropy-based fallback. For secret-shaped variable names (API_KEY, PASSWORD, *_TOKEN) with no recognized vendor prefix, checks the assigned value's character-randomness (Shannon entropy). A real generated credential and "password123" both match a suspicious name, but only one has the entropy of an actual secret — flagged separately and at lower confidence than the vendor-format matches, since this one really is a heuristic.
Every match is redacted before it's returned — the tool never echoes a full secret value back, even to confirm a hit.
Tools
scan_for_secrets
Scans any text (a file's contents, a config snippet) for both categories above.
scan_diff
Scans a unified git diff and only checks lines the diff actually adds — won't flag a secret that was already being removed in the same diff, or one that only appears in unchanged context lines.
Use it
Hosted (recommended): MCPize — free tier, $7/mo Pro.
