Giving an AI agent access to your GitHub account or Slack workspace usually means handing it an API key or token directly, which it then holds in its own memory or context — a real risk if that context ever leaks or the agent misbehaves. Overslash is built to remove that risk: it holds the credentials on your behalf, and the agent asks Overslash to make the call instead of making it directly. Overslash acts as an authentication and action gateway between AI agents and the outside world, supporting GitHub, Slack, AWS, Google Workspace, Notion, Linear, Vercel, PostgreSQL, and any HTTP API. It manages OAuth flows and secrets in a vault the agent never directly sees, offers configurable human-approval gates (deny, approve once, or approve all future calls of that type), and keeps a searchable, exportable, streaming audit log of every call an agent makes and every approval decision. It's natively aligned with the Model Context Protocol (MCP), the same standard Claude and other assistants use to connect to tools. The self-hosted version is free and open-source (MIT/Elastic 2.0 licensed) with unlimited agents and integrations; a hosted Cloud version has a free personal tier and a €3/month per-seat team tier with SSO and shared credentials.

A free health check for AI agents that scans for signs an AI is lying, manipulating, or behaving unpredictably before it causes real damage to your business — like a security scanner, but for an AI's honesty and behavior instead of its code.
A free search engine for security researchers that scans the public web for exposed .env files, open .git folders, and other misconfigured files on any domain.
An automated security guard for apps built with AI coding tools like Cursor or Claude Code — it finds real, exploitable bugs and opens a pull request that fixes them.
Scans the internet for deepfakes and unauthorized AI use of your face or voice, and helps you get paid when someone wants to license your likeness instead.
One dashboard for three things developers usually buy separately — real mobile proxy IPs, phone numbers for SMS verification, and travel eSIMs — all using genuine carrier SIM cards instead of datacenter fakes, with no ID check required.
A security scanner that doesn't just flag possible bugs like most tools — it tries to actually exploit them first, so you only see the ones that are real.
Open-source software that lets a small security team automate their alert-response playbooks — and now AI agents — without paying enterprise SOAR prices.
A tiny command-line tool for backing up SSH keys and other secrets so securely encrypted that you could still recover them in 10 years using nothing but standard Unix tools — even if this tool itself is long gone.
A browser extension you can talk to in plain English to get things done — like "check my email for anything from my accountant" — instead of clicking through the steps yourself, while everything stays inside your own browser.
A password manager that never uploads your passwords to any company's servers — instead, your devices talk to each other directly to stay in sync, so there's no central vault that could ever get hacked or breached.
A hacking-simulation tool that uses a team of AI agents — each specialized like a real penetration-testing crew member — to automatically probe a system for security weaknesses, from initial scanning all the way to proving an exploit works.
Instead of handing your AI agents and scripts your real API keys (which is dangerous if they get compromised), API Stronghold gives them temporary, limited-use tokens that expire in minutes and can't be traced back to your actual credentials.
