Open-Source First

Build email agents on the OSS server. Upgrade to cloud when you need managed operations.

Nerve gives you a production MCP surface for email workflows with a self-hosted core and an optional cloud control plane.

Self-hosted MCP runtime

Run `neuralmaild` on your own infrastructure with full control over data, network, and storage.

Built for modern mailbox APIs with scoped tools for read, search, draft, and send workflows.

Usage events and entitlement checks are enforced in code, with predictable behavior under load.

Keep OSS flexibility while offloading operations-heavy components.
