OK!Sign integration for AI agents.
OK!Sign integration for AI agents with secure authentication and server-side credential injection. Open Connector runs the OAuth, seals the token in an encrypted vault, and serves OK!Sign tools to your agent over MCP or a typed API — credentials injected server-side, every call audited, nothing leaving your infrastructure. Open source (AGPL-3.0) and self-hostable.
Real OK!Sign actions, managed and audited.
Your user connects OK!Sign once; your agent can then free tool to sign documents online. Open an account with 7 FREE credits and create your electronic signature and sign PDF online — scoped to the OAuth permissions you grant and the tool allowlist you configure. Every action is least-privilege and written to a tamper-evident audit trail.

OK!Sign integration, answered
- How do AI agents use OK!Sign through Open Connector?
- Your user connects OK!Sign once with one of its cataloged authentication methods. Open Connector stores the credential in an encrypted vault and exposes OK!Sign tools to your agent over MCP or a typed API, with credentials injected server-side on each call.
- Is this a OK!Sign MCP server?
- Yes. Open Connector can serve OK!Sign as a named MCP server with a scoped allowlist and a per-user connection URL, so any MCP client can call OK!Sign actions with credentials injected server-side.
- Where do OK!Sign credentials live?
- In your own infrastructure. Open Connector keeps credentials in its own vault and injects them at call time, so they never leave your environment.
Give your agents OK!Sign — keep the keys.
