Retell AI
for AI agents.
Retell AI 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 Retell AI 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 Retell AI actions, managed and audited.
Your user connects Retell AI once; your agent can then — 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.
- 01Connect
Your user grants Retell AI access once (OAuth) — the token lands in the vault.
- 02Call
Your agent calls a tool over MCP or the typed API; Open Connector injects the credential server-side.
- 03Audit
Every routed call appends a hash-chained audit record — nothing leaves your infra.

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