If you want an AI agent to actually do something useful — send an email, update a CRM record, check a calendar — it needs credentials to those services. Handing an autonomous agent your real API keys is risky: if it's manipulated or buggy, it now has broad, standing access to everything those keys unlock. Alter Vault exists to remove that risk by sitting between agents and the 100+ SaaS tools they need to reach, issuing narrow, short-lived, revocable credentials instead of raw keys. Alter Vault (a Y Combinator S25 company, originally launched as alterai.dev) manages OAuth tokens and API keys centrally, verifies agent identity, enforces fine-grained policies on what each agent can do, applies rate limits, and keeps a full audit log of every call made through it. It ships Python and TypeScript SDKs, a developer dashboard, and an end-user portal, and is aimed at teams building agent frameworks or chatbots that need real third-party access without the security exposure of static, long-lived credentials scattered across code.

A security layer for companies that let AI agents take real actions on their behalf (booking things, editing databases, sending messages) — it steps in at the exact moment an agent is about to act and checks whether that action is actually safe to run, in
macOS app that intercepts and audits MCP server traffic between Claude Desktop or Cursor and connected tools for security oversight.
Free, in-browser generator for robots.txt and llms.txt files that control which AI crawlers can access your site.
Privacy-first browser side panel AI assistant that works with any model or agent and anonymizes sensitive data before it leaves your browser.
Open-source, developer-first privacy and cookie-consent infrastructure with headless consent flows and version-controlled policies.
Open-source WireGuard-based mesh VPN that replaces traditional VPNs with Zero Trust, identity-based device access.
Invisible, privacy-first bot protection using proof-of-work instead of visual puzzles.
Enterprise policy-enforcement layer that watches what coding agents do — prompts, commands, file changes — and blocks or alerts on sensitive data exposure.
Authorization layer that checks every AI agent action against a policy before it runs, with per-action revocation and a full audit trail.
A free Python command-line tool that checks a website's HTTPS certificate and tells you exactly what's wrong with it — expired, untrusted, wrong hostname — instead of a generic connection error.
An open-source trust-boundary gateway that sits in front of OpenAI, Anthropic and Gemini API traffic to redact PII, enforce rate limits, and track usage without touching your app code.
A free command-line tool that encrypts your .env secrets file so you can safely commit it to Git, with a pre-commit hook that catches accidental leaks before they happen.
