Give your AI agent your API keys without ever showing them to it.

Store your API keys, tokens, and passwords once. Connect one URL to Grok, Claude, Cursor, or ChatGPT. Your agent can then call any API you hold a credential for — it writes {{GITHUB_TOKEN}}, we substitute the real value server-side and make the request. The key never enters the conversation.

Two things that are true by construction

• Your agent never sees your keys. Substitution happens on our server, after the model has written the request.
• We cannot read your keys. Decryption requires your connection token, which exists only inside your MCP client. A dump of our database, even with our own master key, decrypts nothing.

Every key is pinned to one host

A key bound to api.github.com is refused if anything tries to send it somewhere else. A prompt-injected agent cannot exfiltrate it.
