Twelve Data integration for AI agents.
Twelve Data 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 Twelve Data 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 Twelve Data actions, managed and audited.
Your user connects Twelve Data once; your agent can then try Twelve Data financial APIs for free with instant access to stock, forex, cryptocurrency, and fundamental market data. Real time, historical, and EOD data — 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.

Twelve Data integration, answered
- How do AI agents use Twelve Data through Open Connector?
- Your user connects Twelve Data once with one of its cataloged authentication methods. Open Connector stores the credential in an encrypted vault and exposes Twelve Data tools to your agent over MCP or a typed API, with credentials injected server-side on each call.
- Is this a Twelve Data MCP server?
- Yes. Open Connector can serve Twelve Data as a named MCP server with a scoped allowlist and a per-user connection URL, so any MCP client can call Twelve Data actions with credentials injected server-side.
- Where do Twelve Data 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 Twelve Data — keep the keys.
