Samva MCP

Samva

Packages, examples, cookbooks, and agent plugins for building on Samva, the email and WhatsApp API.

Samva takes the routine customer emails off a small business: an AI assistant answers them and asks before it sends. Developers and agent builders build on the same platform. Use this repository to send transactional email, connect auth email flows, work with templates, receive replies and delivery events as signed webhooks, and give an agent its own mailbox. Ask questions about the code on DeepWiki.

Structure

• packages/* — package integrations (@samva/*).
• examples/* — complete, runnable example apps.
• cookbooks/*.md — documentation-first, copy-pasteable recipes.
• plugins/* — coding-agent plugins and public documentation.

While Samva is 0.x, the maintained integrations support only the current SDK minor: 0.35. Workspace packages require samva@^0.35.0 as a peer and test against 0.35.0. Examples use samva@^0.35.0; copyable external import maps pin samva@0.35.0.

Package integrations

• @samva/better-auth — Better Auth email callbacks powered by Samva.
• @samva/email-sdk — Provider-owned Samva community adapter for Email SDK.

Agent plugins

• samva — OpenAI Codex and Cursor packaging for the canonical hosted MCP server and Samva agent skill.
• Samva in ChatGPT — the published ChatGPT plugin is a separate listing from the Codex and Cursor package; the guide covers connecting one organization and a read-only first check.
