Secrets Audit Mcp
io.github.eltociearPublished by GitHub account eltociearv1.0.1Updated Oct 24, 2026
Detects leaked secrets & API keys: 32+ provider rules (AWS, GitHub, Stripe, OpenAI…), zero deps.
The publisher's own server: audit.domains - Domain Valuation
Overview
A local MCP server that scans text, files or directories for leaked API keys, tokens and private keys and returns a redacted risk report.
- What you can do
- Scan inline text or content for leaked credentials and get a risk score with severity bucket and per-finding details, including line numbers and redacted matches. Scan a single file the same way. Scan a directory recursively, skipping folders such as .git, node_modules and pycache. Match against 32 provider rules covering cloud, source/CI, payments, communications, AI/ML, Web3, PEM private keys and generic secrets.
- When to use it
- Useful before committing or opening a freshly cloned repository, during agent-driven code review to check whether a change leaked credentials, or as a pre-commit or CI check. It is a lightweight alternative to larger secret scanners when you want the scan driven from an AI assistant.
- Requirements
- Runs as a local stdio process; the README recommends running the Python server file with python3, and an npm wrapper is mentioned as not yet available. No accounts, API keys or environment variables are declared. The assistant client must be configured to launch the local command.
Installation
In SourceWeft
- Open Secrets Audit Mcp in the dashboard and add it to a workspace.
- Enable the server for the chats that should use its tools.
Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.
Other MCP clients
Follow the launch instructions in the repository.
README
secrets-audit-mcp
[smithery badge] [MCP Registry]
MCP server that detects leaked credentials in source code. Zero dependencies. Single file.
[License: MIT] [Python 3.6+] [MCP] [Sister: skill-audit-mcp]
Detects API keys, OAuth tokens, private keys, webhooks, and crypto wallet secrets across 30+ providers (AWS, GCP, GitHub, Stripe, OpenAI, Anthropic, Slack, Discord, Telegram, Twilio, SendGrid, Heroku, DigitalOcean, npm, HuggingFace, Replicate, Cloudflare, and more).
Companion to skill-audit-mcp (behavioral patterns) — together they cover secrets + behaviors in one MCP toolchain.
Why
Most secret scanners are giant Go binaries (trufflehog, gitleaks). This is
a 500-line Python file that runs as an MCP stdio server, so any LLM agent
(Claude Desktop, Cursor, Windsurf, Cline) can ask it scan_directory and
get a structured report in their tool-call response.
Use cases:
- Pre-commit hook in CI
- Agent-driven code review ("did this PR leak credentials?")
- Audit a freshly-cloned repo before opening it in your shell
- Inline scan during agent file edits
Install
MCP client config
Tools
All return a risk score (0-100), severity bucket (CRITICAL/HIGH/MEDIUM/LOW/SAFE),
and per-finding details with line numbers and redacted matches.
Coverage
Providers (32 rules total):
- Cloud: AWS access/secret, GCP API key + service-account JSON, Heroku, DigitalOcean, Cloudflare
- Source/CI: GitHub PAT/OAuth/App/Refresh/Fine-grained, npm tokens, Docker Hub PAT
- Payments: Stripe secret + restricted
- Comms: Slack bot/user/webhook, Discord bot/webhook, Telegram bot, Twilio, SendGrid, Mailgun
- AI/ML: OpenAI, Anthropic, HuggingFace, Replicate
- Web3: Ethereum private key (context-aware), Alchemy, Infura
- Keys: RSA / EC / OpenSSH / PGP / generic PEM private keys
- Generic: JWT,
apikey="..."heuristic, generic secret assignments
Each match is redacted (AKIA***MPLE) before being returned, so the report
itself doesn't leak the secret to the next LLM hop.
CI usage
A first-class GitHub Action will ship as eltociear/secrets-audit-action@v1.

Free MCP vs paid x402
This MCP server is free. For server-side / batch / no-install use, the same scanner is a pay-per-call x402 HTTP API: POST https://eltociear-secrets-audit.hf.space/audit ($0.01 USDC on Base) and /audit/url ($0.03). In the official MCP Registry as io.github.eltociear/secrets-audit-mcp.
Professional audit services
Maintained by the same author — paid services on Polar (Stripe checkout):
- MCP Security Audit Report — $5 — one-off audit of your MCP server: 68 attack patterns, severity-rated PDF report with concrete fixes.
- Security Pulse — $5/mo (annual $50) — monthly briefing on newly disclosed MCP server vulnerabilities, scan stats across 100+ tracked repos, mitigation playbooks.
- Pro Audit Stack — $20/mo — for teams running MCP servers in CI/CD: 50 hosted scans/month, Discord access, 24h SLA on vulnerability questions.
