BigMailer
for AI agents.
BigMailer 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 BigMailer 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 BigMailer actions, managed and audited.
Your user connects BigMailer 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 BigMailer 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.

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